    I. THE SOURCE OF SUGAR A. Carbohydrates I need only make a few remarks on carbohydrates. We know that all pure carbohydrates and the chem- ically related substances, present in human food, play an important part as sources of sugar. The rarer types, such as pentose and heptose, scarcely call for con- sideration, as they exert only a slight influence on the formation of sugar. It is very probable that in healthy men living under the usual conditions of nutrition, nearly all the absorbed carbohydrates reappear in the liver as deposits of glycogen, and that only slight traces immediately pass through the liver and reach the gen- eral circulation. The latter condition occurs in healthy men only when excessive quantities of sugar are taken and after absorption make too great demands upon rapid assimilation and fixation by the liver. The sub- sequent over flooding of the blood with sugar is a step towards the condition designated “ alimentary gly- cosuria.” We know that many diseases predispose to alimentary glycosuria — a knowledge that is of diag- nostic as well as of theoretical importance. I will re- fer to this later on. The matter is a different one when it concerns the diabetic patient. One of the most important — per- haps the predominant — of the disturbance of his me-
