In the last few years our knowledge concerning sugar in the circulating blood has made considerable advances.1 The keen interest aroused by the questions concerned with glycemia has led to the perfection of numerous methods which in turn have resulted in greater numbers of cases being studied. The importance of the study of the blood-sugar is well emphasized by Scott,2 who says:
Glycemia offers a more satisfactory indication of the condition of mobile sugar than does glycosuria; first because either an increase or a decrease in the amount of sugar may be demonstrated, while normal urine can show only an increase; secondly, because profound changes in glycemia may occur in response to conditions which do not produce glycosuria; thirdly the blood is in much more direct relation to the living cells than is the urine.
Though the variety of methods used has led to slightly divergent readings, it
