"Every physician given a license to practice must take an oath that he shall faithfully fulfil all the requirements of the law, and in addition, whenever it comes to his knowledge that any apothecary has for sale drugs that are of less than normal strength, he shall report him to the court, and besides he shall give his advice to the poor without asking for any compensation. A physician shall visit his patient at least twice a day, and at the wish of his patient once also at night, and shall charge him, in case the visit does not {422} require him to go out of the village or beyond the walls of the city, not more than one-half tarrene in gold for each day's service." (A tarrene in gold was equal to about thirty cents of our money. Money had at least twenty times the purchasing power at that time that it has now. At the end of the thirteenth century, according to an Act of the English Parliament, a workman received 4d [eight cents] a day for his labor, and according to the same Act of Parliament the following prices were charged for commodities: A pair of shoes cost eight cents, that is, a day's wages. A fat goose cost seven cents, less than a day's wages. A fat sheep unshorn cost thirty-five cents; shorn, about twenty-five cents. For four days pay a man could get enough meat for himself and family to live on for a week, besides material out of which his wife could make excellent garments for the family. A fat hog cost twice as much as a fat sheep, and a bullock about six times as much.--J. J. W.) "From a patient whom he visits outside of the village or the wall of the town, the physician has a right to demand for a day's service not more than three tarrenes, to which maybe added, however, his expenses, provided that he does not demand more than four tarrenes altogether.
