THE VARIATIONS IN THE CONTENT OF SUGAR IN THE BLOOD

Alimentary glycosuria, as exhibited in the renal excretion of sugar when undue amounts of carbohydrates are ingested by persons who fail to manifest this symptom under ordinary conditions of diet, has long been recognized and investigated. The prominence which the clinical estimation of the sugar-content of the blood has assumed in recent months, and the diagnostic importance which has been attached to the variations in this blood-constant as a possible index of incipient metabolic disorder, have seemed to call for a careful determination of the precise effect which the ingestion of carbohydrate may exert in altering the quantum of blood-sugar under well controlled conditions in otherwise healthy persons. The determination of normal values and physiologic deviations from them is always essential as the rational beginning in the establishment of a new scheme of diagnostic procedure. Such an undertaking has lately been carried out in the medical clinic of the University
