The Plover's skipper, Commander Rochefort Maguire
Eskimos who were meeting white men for the first time were living beyond 80 despite eating only meat and smoking Chinese tobacco.
This was, it seems, Dr. Simpson's first experience, as well as the captain's, with the typical heat of northern Alaskan winter dwellings. Simpson kept revisiting Eskimo homes during the seven winter months of two years. He describes a healthy and happy people of apparently high longevity who, during the winter, lived practically naked — the children wholly so — in earth and wood dwellings that were seldom cooler than 70° F., who avoided all vegetable foods and salt, and who lived on fat and lean fresh meats that were undercooked or raw. Sweating in temperatures which, during the afternoon and evening, ran to 90° and 100° F., they drank ice water continually.
The only non-native “foods” the Barrow people used in Simpson's time were tea and tobacco, which they had been receiving overland and across the Bering Strait from China long before the Russian “discovery” of Alaska. The tobacco the Barrow people, like all Alaskan Eskimos, smoked in Chinese opium-type pipes, inhaling the smoke. They also chewed; but they did not spit, swallowing the juice instead. They did not, apparently, dip or snuff. Following are a few of Simpson's passages that bear on food and food habits, health and longevity:
“These people ... are robust, muscular and active, inclining rather to spareness than corpulence ... presenting a remarkably healthy appearance ... The expression of the countenance is one of habitual good humor ... The physical constitution of both sexes is strong ... Extreme longevity is probably not unknown among them; but as they take no heed to number the years as they pass they can form no guess of their own ages ... Judging altogether from appearance ... [one man] could not be less than eighty years of age ... There was another ... whose appearance indicated an age nothing short of seventy five. This man died in the month of April 1853 ... There is another man still alive who is said to be a few years older ...

Obesity, Carnivore, Keto
Obesity, or, Excessive corpulence: the various causes and the rational means of cure
A landlord at the Golden Lion Hotel loses 90 pounds going from 270 to 160, and tells many about Dancel's meat-cure. He wrote in a letter: "Immediately after adopting your system, my fat began to disappear, my appetite improved, and, after a few months, my weight was reduced to one hundred and sixty pounds, and my circumference to thirty-two inches. My health is now excellent."
Towards the latter end of 1851, Madame Wimy, from the town of Marle, came to consult me in reference to her husband, who was labouring under obesity to such a degree as to be unable to attend to his business. I gave her the necessary advice, together with some medicine. On the 19th of December Madame Wimy told me by letter that her husband had already much improved, that his breathing was easier, he was more capable of exertion, and that his corpulence had notably diminished. This lady again wrote to me in the following year, requesting a further supply of medicine. She said:—"My husband, before commencing your treatment, weighed two hundred and seventy pounds: he now weighs only two hundred, and hopes to weigh still less. You are no doubt in the frequent receipt of letters seeking advice, for we have many inquiries for your address."
In truth the case of M. Wimy has brought me a great many patients. Anxious to know whether he still continued my plan of treatment, and wishing to introduce a statement of his case in this the third edition of my work, I wrote to M. Wimy on the 16th of October last and received the following reply:
"Marle, 19th Oct., 1853.
"Sir,—In your letter of the 16th, you requested me to give a somewhat detailed statement of my case. I commenced the treatment under your directions, the latter part of 1851, and continued it during the early part of 1852. My weight was two hundred and seventy pounds, and I measured sixty-one inches in circumference. I walked with great difficulty—suffered much pain in the kidneys—my legs were swollen. I had a constant cough, and was much troubled with drowsiness. Immediately after adopting your system, my fat began to disappear, my appetite improved, and, after a few months, my weight was reduced to one hundred and sixty pounds, and my circumference to thirty-two inches. My health is now excellent. Being landlord of the Golden Lion Hotel, at Marle, where the stages put up, my recovery is known to a great many; and travellers who stopped at my house two years ago, when I was labouring under obesity, on seeing me at present, and noticing the wonderful change which has taken place, invariably ask by what means it has been effected.
"It always affords me great pleasure to acknowledge that my cure is due to your system of treatment.
"I have the honour to be, &c.,
"Jules Wimy.
"Golden Lion Hotel,
Marle, Aisne."
A person who visited Marle about four months ago, and who had not seen M. Wimy since the great change had been effected in his appearance, was much astonished, and made inquiries respecting the cure. Some time afterwards, this person met, at Orleans, a wealthy gentleman, about forty years of age, suffering from obesity, and told him what he had witnessed at Marle; recommending him at the same time to visit Paris, in order that he might have the advice of the doctor who had freed Wimy from his excessive fat. This gentleman wrote to Marle, before coming to Paris, and received a satisfactory answer.
He called to consult with me, saying that he wished to place himself under my care, provided that it would not interfere with his business or with his usual habits. He is postmaster at Orleans, and, previous to the building of the railroad, had a great deal of business to attend to. Having many more horses than necessary for his business at Orleans, he has opened a livery stable in Paris. He is consequently obliged to attend all the fairs and markets, in order to purchase horses and provender for his two establishments,—the one at Paris and the other at Orleans, and is almost constantly travelling between these two cities, and therefore leads a life of great activity. He weighs two hundred and twenty-two pounds, and wishes to lose fifty pounds of fat, but he cannot afford to lose a day from his business.
My reply to Mr. M. was, that so far from my treatment demanding any cessation from work, it would rather give him strength to carry it on. He began the treatment ten weeks since, and has already lost between twenty-eight and thirty pounds of fat; and, as I had promised, without causing him the loss of a single day.

Salisbury Steak: Civil War Health Food: After 30 years of research Dr. Salisbury finally published his ideas, setting off one of the earliest American fad diets
Salisbury describes how he discovered the all meat diet: "In 1854 the idea came to me, in one of my solitary hours, to try the effects of living exclusively upon one food at a time."
The first step is to wash out the sour stomach and bowels , and to change the food. The food selected should be such as is least liable to ferment with alcohol and acid yeasts. This is muscle pulp of beef, prepared as heretofore described, when it affords the maximum of nourishment with the minimum of effort to the digestive organs. Nothing else but this food, except an occasional change to broiled mutton.
In the preface, Salisbury described the research that led him to his conclusion:
"In 1854 the idea came to me, in one of my solitary hours, to try the effects of living exclusively upon one food at a time. This experiment I began upon myself alone at first…. I opened this line of experiments with baked beans. I had not lived upon this food over three days before light began to break. I became very flatulent and constipated, head dizzy, ears ringing, limbs prickly, and was wholly unfitted for mental work. The microscopic examination of passages showed that the bean food did not digest."
Did the intrepid scientist stop there? Of course not! In 1858 he enlisted six other schlemiels to come live with him and eat nothing but baked beans. He did not mention whether he had a wife who had to put up with seven flatulent, dizzy mopes in her home; my guess is no. Later he and four other guys subsisted solely on oatmeal porridge for 30 days. Other single-food experiments followed, leading him to the conclusion that lean beef, minced to break down any connective tissue and fully cooked, was the best and most easily digested food. By the time the Civil War started, in 1861, he was ready to test his theories on suffering soldiers.

The Philosophy of the Stomach; on, an Exclusively Animal Diet (Without any vegetable or condiment whatever) is the Most Wholesome and Fit for Man. Illustrated by Experiments upon Himself.
German writer, Bernard Moncriff, discovers an exclusively animal based diet and conducts several dietary experiments that lead him to conclude this diet is superior to a mixed or vegetarian diet.
https://www.reddit.com/r/zerocarb/comments/hnuott/the_philosophy_of_the_stomach_or_an_exclusively/
I have recently come across a vintage book that caught my attention. It was published by a German writer, Bernard Moncriff, in 1856 in London. The author supposedly experienced remarkable health benefits on an exclusively animal diet and even conducted a few dietary experiments. He also attempted to bring attention of the contemporary scientific community and general public to this diet as being superior to the mixed and vegetarian ones. In his opinion, humans could and should live exclusively on an animal diet.
Below are some of the highlights I made while reading it that you may find interesting:
"I cannot help looking upon much of what has been written about the stomach and digestion with a similar smile to that of modern astronomers when perusing astrological works".
"I like the sweetness of milk better than that of sugar, and the acidity of meat better than that of fruits".
"Among all beverages I like milk best, hence I take no other fluid but milk. Of all eatables I like meat best, I eat, therefore, of it in preference to anything else".
"Wholesomeness, was, and is my principal motive in adhering to an exclusively animal diet".
"I do not eat for the mere sake of gratifying my palate, but to satisfy my appetite, I cease eating when I have had enough. But with your condiments, drugs, and drinks, you cannot say when you have had enough".
"Leave the appetite sole master to determine the hours and frequency of the meals, as well as the quantity of food. I now make most frequently only two meals of meat daily, while I take a glass of milk whenever I please. As a rule, however, I take nothing in the last two hours before going to bed, which greatly contributes to the uninterrupted soundness of sleep".
"The most wholesome diet is that which requires the least quantity of matter to be introduced into the digestive cavity for the support of the system".
"The quantity of animal food required for the full support of the system is so much smaller, as to constitute a very considerable diminution of blood flowing into the heart and the lungs, - I hope to see it generally admitted that the strength of men would be much increased by their adoption of my diet. I myself have experienced a considerable increase of the strength of my body, especially as far as locomotion is concerned. I run over the same distance in nearly the third part of the time it took me formerly".
"Plain butcher's meat, from a roast joint, is more than six times as nutritive as potatoes, and more than seven times as nutritive than wheaten bread".
"It has also been found, not alone as a matter of general personal experience, but by direct experiment, that animal food is more digestible than vegetable food".
"Men had better abstain altogether from fruits and everything else unfavorable to the teeth or the stomach. Fruits, it would appear, are destined in the economy of nature for birds, which are destitute of teeth, and the bill of which is constructed exactly of that substance Professor Valentin would have our teeth made of. All vegetables are, in my opinion, fit only for animals, which in their turn are to serve as food for man".
"There will be a time when the entire human race will live upon an exclusively animal diet".
"An exclusively animal diet, on the contrary, is capable of being adopted by the entire human race, and in all corners of the globe, under the burning sun of Africa as well as the Arctic regions".
"Children brought up with an exclusively animal diet, and made conscious of the great advantages of such diet, would stand proof against the temptations of pot-houses as well as of divans".
"The matter introduced into my stomach daily is not much more than the third part of that previous to my change of diet, my appetite is much better satisfied, and my body stronger than formerly".
"Meat is the food which does the least, if any injury to the teeth, either mechanically or chemically. Not to speak of vegetable fibers and grains by which the teeth of the vegetarian animals are being worn away, even mealy and pulpy vegetables, as bread and potatoes, are acting in the same direction, though to a less degree, by their attrition".
"An exclusively animal diet is unique, simple, and harmonious in its character, although the articles may be derived from animals of various orders. Because there is less chemical difference between the flesh of an elephant and that of a chicken, or a salmon, then there often exists between the potatoes of one and the same field".
“My face, from being rather shallow, became clear and youthful, my eyes serene and mirrors of happiness. It gave me unknown, or rather, forgotten pleasure, to jump over ditch and hedge, and to make those exercises which required muscular strength”.
"I have not felt the slightest disagreeableness arising from the bowels, either in the shape of eructations from the stomach, or obstruction, or dysentery, or of any denomination whatever. Indeed, it if was not from memory, and from books, I should not know that I had such things as a stomach and intestines. The evacuation of the bowels takes place with ease and regularity once every other day. The quantity of both urine and feces is, as might be expected, much less than formerly. My nasal secretion has also very much diminished; and my throat and mouth being perfectly clean, I have no occasion to spit".
"My nasal secretion has, together with the other secretions, greatly diminished, especially since I replaced a quantity of milk by meat".
"It is extremely probable that my bladder, liver, stomach, and the rest of the intestinal canal have gradually decreased in size, which is the case with every animal changing a vegetable for a carnivorous diet. So, for instance the tadpole, which lives upon vegetables, possesses an extremely long digestive tube; but in its perfect state, and when its appetite has become altogether carnivorous, the intestines become very much shortened, losing four-fifths of the length".
"The mouth of man has not been made to kill the prey, but to eat its flesh, for which purpose the teeth, tongue, and the whole gustatory apparatus, are admirably adapted".
"The mere form of the human teeth matters very little in a dietetical point of view. Knife and fork will outmatch the most formidable cutting teeth of any lion or any antediluvian monster".
"The stomach, however, does not tax the articles by their marketable price, but by their weight, digestibility, and other chemical and mechanical properties. There is no such thing as neutrality in our system. Everything that enters it must do something - either good or bad".
"For six days consecutively I took, instead of meat, two pounds and a quarter of baked potatoes daily, without salt or any other ingredient. My appetite was not at all as well satisfied as with the three-quarters of a pound of meat, and I felt also a greater thirst to quench, for which I was obliged to take more than two pounds weight of water, besides the usual quantity of milk".
"I made a similar experiment with home-made wheaten bread, free from salt and other ingredients, for eight days continually. I took two pounds and a half of bread instead of meat, without my appetite being satisfied, while the thirst was still greater than was the case with respect to the potatoes so as to oblige me taking, besides the milk, more than two pounds and a half of water".
"Of omnivorous animals it has also been observed, that they preferred animal to vegetable food".
"The teeth of carnivorous animals in a state of nature have not been seen to be decayed, what is always the case with those of vegetable eaters. The dog, which is often subject to toothache, has probably to thank this to the corruption his natural diet is undergoing in the domesticated state".
"The domesticated cat, which lives on a mixed diet, has its intestines two-fifths longer than the wild cat".
"While colds and pulmonary diseases are common among cattle, they are rarely, if at all to be met with among carnivorous animals".
"I may assert without fear of contradiction, that all dead animal matter introduced somehow or other into the digestive cavity of every animal, without an exception, is being converted into living matter of the same animal".
"Some plants live upon some other plants, but no plant can convert every other vegetable matter into its own living matter, and the mutual convertibility is entirely wanting. I presume, therefore, that the unlimited mutual convertibility is a single character, sufficient to mark the line between the two kingdoms; it being present in the animal, and absent from the vegetable kingdom. It is this chemical similarity and mutual convertibility which gives to an exclusively animal diet the character of singleness, simplicity, and harmony".
"The great superiority of strength of the carnivorous over the vegetarian animals is due to this double ration, namely, the greater development of the lungs, and the smaller size of the abdominal contents".
"The first repulsive effects of most condiments, liquors, tea, coffee, and etc, are quite forgotten by most people, these articles being, unfortunately, introduced into the diet of children of all classes. Yet it is frequently to be observed of children, not yet quite habituated differently, that they reject, when left to their own choice, everything salt, sour, bitter, and hot".
"The popular notion is still in vogue, according to which every eatable and drinkable thing, either in a state of nature or manufactured, is to be presumed as wholesome and fit for man, until the contrary be proven. This notion is based upon another popular notion, that everything has been made to suit man. The truth, however, is, that man, though entitled to eat, or use otherwise, everything he can take hold of, meets with a comparatively very small number of vegetables that suit him well".
"I have been very scrupulous to observe the rule, not to take of anything but as much as my stomach can easily digest, and to use those things only which agree with me".
"A sound appetite ought not to be restrained, such appetite being the indication of the wants of the system, which must be satisfied to the full".
"A perfectly healthy man could have only one appetite, and this a sound one, while the false appetite could only exist with imperfect health".
"Man should have been furnished with a sense of taste so perverted as to make him like those things best which are the least wholesome for him".
"Brutes spurn whatever is hurtful to them, and distinguish poisonous plants from salutary by natural instinct; and that they eat only of noxious plants when pressed by extreme hunger".
"Men had better eat to live, than live to eat".
Another Review also helps elucidate Moncriff's writing.
Moncriff sets out an ambitious project of arguing against the traditionally accepted view by the medical doctors that mixed diet or
eating vegetables is more nutritious for us, and instead takes a view that an exclusive animal diet is the true path to follow if we want to be healthy. He argues that consulting doctors about what our diet should be is ridiculous, since “the healthy want no doctors, and if they wish to know how to preserve their health, they must first study themselves, and then learn from others the means by which these have actually succeeded,” and warns the doctors that they too should learn from his principles, which offers “perfect health and true enjoyment of life.” He repeatedly instructs us that it is important not to consume anything that is disagreeable to our stomach, however agreeable it may appear to be to our palate. It is in this spirit that he writes his account of the philosophy of the stomach as “a seed of life strewn in the future.”
He begins his investigation by supposing that we should be able to tell naturally what food is hurtful to us and what is not, just as “brutes can spur whatever is hurtful to them, and distinguish poisonous plants from salutary, by natural instinct… [and] only such as either accidentally or pressed by extreme hunger eat of it.” But our experience tells us that we taste junk food agreeable to our palate, even though we know it is bad for us. Can we really tell what is disagreeable to our stomach simply by something’s being agreeable or disagreeable to our palate?
Having first complained that his paper was rejected by a number of journals for his novel, and consequently incredible, idea of commencement of exclusive animal diet, he explains to us that the present condition of our palate is not conducive to the experiment to finding out that animal diet is in fact the healthiest human diet. This is because our palate, after a long abuse by eating artificially added condiments on cooked food, has been confused as to what tastes essentially good to us. So his first step is to get rid of this confusion from our palate, and only then can we have a sound appetite, as he is convinced that “there could be no unison between a sound, or true appetite, and a false one; that a perfectly healthy man could have only one appetite, and this a sound one, while the false appetite could only exist with imperfect health.” He argues that had we been truly healthy and our palate not corrupted, we would be able to know instinctively, just like those brutes in the wild, what is wholesome and would come to “reject everything unwholesome to [us], not out of a knowledge of its unwholesomeness, but simply because it was repulsive or indifferent to [our] taste.” In order to achieve a immaculate taste, as if in infancy, he spends six months or so “exclusively or mainly upon plain milk, without sugar, salt, or any condiment whatever,” and “I thus made myself, as it were, a baby again, fancying for a moment dietetics as a ‘tabula rasa,’ and myself as having nothing to guide me except my own experience.”
After six months of nothing but milk and almonds, “[m]y face, from being rather shallow, became clear and youthful, my eyes serene and mirrors of happiness,” and “[i]t gave me unknown, or rather, forgotten pleasure, to jump over ditch and hedge, and to make those exercises which required muscular strength.” In this way, he recounts that he had never been happier and felt healthier than before, resulting in him being “always cheerful, indulging frequently in songs.” Indeed, he now tells us that it is such a miserable pittance to have a sumptuous dinner, compared to having a single hour of perfect health and true enjoyment of life.
However, this is only the first phrase of his project. He now spends the next twelve months eating only fresh meat and milk. It has frequently been said in opposition to animal diet that it can be least economical in supporting us. Yet, he fends off this claim by providing us with the information about how much quantity of meat and milk he has consumed, and proves that it is much more economical than mixed diets.
He further reports that since he began his exclusive animal diet, he has “not felt the slightest disagreeableness arising from the bowels, either in the shape of eructations from the stomach, or obstruction, or dysentery, or of any denomination whatever.” Further, he entertains us with the empirical account of his that the “quantity of both urine and feces is, as might be expected, much less than formerly,” and is pleasantly surprised that “no bad odour is to be detected in the latter.”
He also has a rather teleological as well as functional argument that meat does not injure our teeth either mechanically or chemically, as vegetables are known to do with fibres and grains mechanically, and with fruits chemically, for “[a]cid, even when considerably diluted, corrode the enamel, and penetrate in small quantities into the dental sac,” not to mention there is this inconvenience arising from “the cracking of hady substances, as nuts, &c., by which the enamel is often being broken,” which results in the “subsequent destruction of the teeth unavoidable.”
In like manner, he argues that fruits are to be consumed only by birds who are destitute of teeth,” and concludes that “there is not a slightest doubt in my mind that there will be a time when the entire human race will live upon an exclusively animal diet.”
His extensive empirical study of the stomach is resonant of the period in many ways, as his argument is based on a quantitative science as is echoed from his citation from Lavoisier, yet his argument from functions and teleology shows the kind of science done during the period, as Darwin would publish his book on the Origin of Species in the following years. His inclination to empiricism does not, however, reject a rational theoretical science, as he says at one point that “a man without grand theories will never arrive at a great fact.” Yet in the end, his commitment in the science lies in the belief often seen in the progressive thinkers that when the fact is found, “the theories must be relinquished or corrected without hesitation.” In sum, this book offers an alternative view on a rational ground to the currently predominant view that vegetable diet is healthier than and preferable to the exclusive animal diet.

EXPERIMENTS WITH " BAKED BEANS " AS AN EXCLUSIVE DIET, UPON STRONG HEALTHY MEN.
Dr Salisbury hires six men to live upon a diet of only baked beans and coffee, but after 18 days, they "all presented such a forlorn, dilapidated appearance" that the doctor ordered a beef only diet to help them recover so that in just a few days "All felt unusually well, clear headed and happy."
XLIX. EXPERIMENTS WITH " BAKED BEANS " AS AN EXCLUSIVE DIET, UPON STRONG HEALTHY MEN.
In September, 1856, I engaged six strong, healthy men, in the vigor of life, ranging in age from 25 to 40 years, to feed upon a special line of diet solely, with the understanding that I would pay them $30 per month each, if they submitted faithfully to the rigid discipline laid down. At the same time I explained to them the kind of food upon which I should require them to live, the exercise and other regulations marked out. All thought the diet and drinks could be easily endured, in fact, enjoyed, especially as they would have no manual labor to perform. They all entered upon the undertaking with the feeling that they would have a fine time at my expense. The diet consisted first of baked beans and coffee. This to continue for one month or until otherwise ordered by me. Exercise to be a two-mile walk, morning and evening. To retu'e at 9 p. m. and rise at 6 a. m. Drinks between meals, cold water. On the 13th of September, the experiments began. Breakfast at 7 a. m., dinner at 12 noon, and supper at 6 p. m. I shall designate my six boarders by the letters A, B, C, D, E, F. All were strong, robust, free from disease, and having one regular movement of the bowels every day.
A weighed 160 lbs. Age 36 yrs.
B --145 lbs--30 yrs
C--155--40
D--166-- 34
E--172--28
F--148--25
The first day all felt well and enjoyed themselves greatly.
Towards evening began to bloat, but had no special feeling of discomfort. Slept well. Entered upon the second day feeling about as well as on the first, except that all were flatulent and constipated. Yet all had a scanty, hard movement of the bowels before evening. In the after part of the day they were very uncomfortable from the bloating. Took them on a brisk walk of two miles, which was something of a relief.
Symptoms of Progressive Paralysis or Locomotor Ataxy began to show themselves in all six cases on tenth clay. These paralytic and peculiar symptoms increased each day after the tenth. On sixteenth day the disease was so marked, that not one of the six could walk straight without support. All wobbled and dragged their legs, not being able to lift them clear of the floor.
My boarders, on the 19th morning, all presented such a forlorn, dilapidated appearance, that I feared I should lose my reputation as a caterer, and also all my guests, unless I changed my diet list. They had all lost heavily in weight, and were much debilitated.
A weighed 138 lbs. Loss in 18 days 22 lbs.
B 116 " " " 29 "
C " 136 " " " 19 "
D " 143 " " " 23 "
E " 147 " " " 25 "
F " 126 " " " 22 "
"When on the morning of the 19th day, I set before them nice beefsteaks, freed from fat and white tissue, they were all greatly delighted and ate ravenously of them. I gave to each 10 ounces of meat, with a good cup of clear coffee. Beef seasoned with butter, pepper and salt ; no other food or drinks. At dinner gave each 12 ounces of beefsteak, prepared as for breakfast, and half a pint of clear tea. The meal was hugely enjoyed.
All now began to breathe easier and to feel clearer about the head. Passages less frequent, though still large and numerous. During the afternoon, all were in a state of enjoyable relief, and were ready to speak a good word for their host and his house.
At supper, gave each 10 ounces of beefsteak, with a cup of clear tea. The meal was greatly relished. The eveuing was a pleasant one, all having a sense of relief from the extreme flatidence, bewildered heads, oppressed breathing and numbness of previous days. Retired at 9 p. m. All slept soundly and were ready to rise at 6 a. m. on the 20th morning. For breakfast, gave to each 12 ounces of broiled steak and haK a pint of clear coffee. Passages from bowels greatly lessened in quantity and frequency. Bloating almost gone. Heads quite clear, and all cheerful and happy. At dinner, gave each 1 lb. of nice broiled steak and half a pint of clear tea : meal greatly relished. All felt well and began to lose their haggard, shrunken look. Circulation good ; heads clear ; bloating gone ; movements beginning to be quite natural and few in number. At supper gave to each 12 ounces of broiled steak and half a pint of clear tea. All felt well during the evening. Retired at 9 p. m. Slept soundly.
Called up on 21st day at 6 a. m. All feeling well and anxious for breakfast. Gave each 1 lb. of broiled steak and half a slice of bread, with half a pint of clear coffee. All enjoyed the breakfast. Half an hour after breakfast gave them a brisk walk of two miles. All well, and felt better, brighter and clearer than before the experiments began. Bloating, diarrhoea, ringing in ears and dizzy head all gone. At dinner gave to each 1 lb. beefsteak, 1 slice of bread and half a pint of clear tea. No diarrhoea ; stools quite natural except more profuse. At supper gave each 14 ounces of broiled steak, half a shce of bread, and half a pint of clear tea. Meal greatly enjoyed. All gaining rapidly in strength and feeling splendidly. Retired at 9 p. m. All slept soundly.
Called up on 22d morning at 6 a. m. All in good trim, and loud in their praise of their host and his table. Gave each 1 lb. of broiled steak, half a pint of clear coffee and a slice of bread and butter. The meal was much enjoyed. All felt unusually well, clear headed and happy. Half an hour after breakfast gave them a long walk. At 12 m. each had 1 lb. of broiled steak, a slice of bread and a cup of clear coffee, which they took with great relish. After finishing the meal, I paid off my boarders and discharged them. With a feeling of regret and reluctance (I think on both sides) we separated. Still, they could not realize how I could keep up and "make both ends meet," while running a boarding house on this plan. I may add that I had throughout shared their diet, discipline and experiences in all respects.

Neanderthal diet at Vindija and Neanderthal predation: The evidence from stable isotopes
The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources
Archeological analysis of faunal remains and of lithic and bone tools has suggested that hunting of medium to large mammals was a major element of Neanderthal subsistence. Plant foods are almost invisible in the archeological record, and it is impossible to estimate accurately their dietary importance. However, stable isotope (13C and 15N) analysis of mammal bone collagen provides a direct measure of diet and has been applied to two Neanderthals and various faunal species from Vindija Cave, Croatia. The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources. Earlier Neanderthals in France and Belgium have yielded similar results, and a pattern of European Neander- thal adaptation as carnivores is emerging. These data reinforce current taphonomic assessments of associated faunal elements and make it unlikely that the Neanderthals were acquiring animal protein principally through scavenging. Instead, these findings portray them as effective predators.
Stable Isotope Analyses.
Mammal bone collagen δ13C and δ15N values reflect the δ13C and δ15N values of dietary protein (14). They furnish a long-term record of diet, giving the average δ13C and δ15N values of all of the protein consumed over the last years of the measured individual's life. δ13C values can be used to discriminate between terrestrial and marine dietary protein in humans and other mammals (15, 16). In addition, because of the canopy effect, species that live in forest environments can have δ13C values that are more negative than species that live in open environments (17). δ15N values are, on average, 2–4‰ higher than the average δ15N value of the protein consumed (18). Therefore, δ15N values can be used to determine the trophic level of the protein consumed. By measuring the δ13C and δ15N values of various fauna in a paleo-ecosystem, it is possible to reconstruct the trophic level relationships within that ecosystem. Therefore, by comparing the δ13C and δ15N values of omnivores such as hominids with the values of herbivores and carnivores from the same ecosystem, it is possible to determine whether those omnivores were obtaining dietary protein from plant or animal sources.

We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus
We undertook stable isotope analysis of Upper Palaeolithic humans and fauna from the sites of Gough's Cave and Sun Hole Cave, Somerset, U.K., for palaeodietary reconstruction. We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus. There are a large number ofEquus sp. faunal remains from this site, but this species was not a significant food resource in the diets of these Upper Palaeolithic humans.
If the humans hunted and consumed mainly horse, then their 15N values should be c. 3–5‰ (Equus 15N value of 0·7‰+enrichment of 2–4‰). Instead, their 15N values make more sense if they lived mostly off Bos and Cervus elaphus (Bos and Cervus values of c. 3‰+enrichment of 2–4‰=the observed values c. 6–7‰). It is also possible that other species, including Rangifer tarandus, were consumed by these individuals. Rangifer tarandus has 15N values similar to Cervus elaphus (Richards, 1998), and has more positive 13C values, which may explain the observed slight enrichment in the human 13C values. A number of artefacts made from Rangifer tarandus have been found at Gough’s, but there is no other evidence that this species was being exploited for food
