The data available in the literature on dextrose tolerance in infancy are both meager and scattered (table 1). It is stated that the blood sugar curve of infants after ingestion of carbohydrate is similar to that of adults, but is flatter. However, the procedure followed and the technic employed in determining the curves of infants, with one or two exceptions, differ so widely from those employed in determining the sugar curves of adults that it hardly seems justifiable to compare the curves.
In 1914, Mogwitz1 studied the tolerance of six infants between the ages of 4 and 13 months. In five cases, the level of the blood sugar was determined after the infant's ingestion of milk in such quantity that it received from 1 to 4 Gm. of lactose per kilogram of body weight. In the sixth case, that of an infant 11 months of age, the level of
