In a previous communication,1 it was shown that the relative hydration of the organism had a profound effect on the sugar metabolism. If one-half unit of insulin per kilogram of body weight was injected into dogs in varying degrees of dehydration, the hypoglycemic effect was not only intensified, but it was also materially prolonged. This paper consists of further studies on the subject.
The experiments were repeated on diabetic dogs. We used not only dogs with complete diabetes, but also a dog in which the diabetes was not complete, so that he was able to remain in fairly good health for several months without the use of insulin, except as it was required for the experiments. The blood sugar estimations were made by the micro method of Folin-Wu.2
