    sti'iven hard, it is true, to upset the evidence that has been adduced iu favour of the glucoside constitution of proteid matter. In speaking of the crystalline osazone I have obtained from the cleaved sugar, he says the carbohydrates are not the only bodies which yield crystalline compounds with phenyl-hydrazine, and that It is only when an elementary analysis of the compound is made that it can be definitely con- cluded that a carbohydrate is a constituent part. The elementary analysis has now been made and definitely shows the crystalline compound obtained to be a sugar osazone. The details of the work are given in a previous part of this epicriticism. I take it therefore that Dr. Paton will now admit that ground no longer exists for him to hold to his state- ment that the existence of a carbohydrate element in the proteid molecule cannot be accepted. Finally, Dr. Paton comments on the interest attach- ing to some recently published experiments of Kauf- mann on section of the nerves of the liver and pancreas in connection Avith Bernard's diabetic punc- ture of the fourth ventricle, and in the preceding short paragraph says, Then how does this theory [the system of knowledge propounded by me] explain the diabetes which follows extirpation of the pancreas ? Dr. Pavy simply ignores this problem. No doubt there is interest attaohing to the effect of operations on the nervous system in leading to the
