risky procedure. I do not dare to look up how much of the free-bed money for diabetic patients in the New England Deaconess Hospital is spent on neglected toes, but I venture to say that the charity money devoted to the toes of elderly patients is five times that expended on diabetic patients in their teens. Consider the difference in the efficiency and expectation of life of the two groups.A defeatist policy will never win a diabetic war.Always attack diabetes aggressively the more aggression, the younger the diabetic and the more recent the onset of the disease. Best2 has shown that diabetes can be prevented in a dog following the injection of anterior pituitary extract, provided insulin is simultaneously administered. Indeed, if a dog is fasting it is impossible to give it diabetes by the injection of anterior pituitary extract. Lukens3 has shown in a cat that even after two months the diabetes definitely produced by injections of anterior pituitary extract can be cured by energetic treatment with insulin. In the cat, for some months following the development of the disease, the islands of Langerhans in the pancreas are in the stage of hydropic degeneration, and in that stage the lesions are reversible and the diabetes can be cured.How thankful I am that the words "prevention" and "cure" have now entered the vocabulary associated with diabetes, even though they apply alone to experimental diabetes in an animal. There is no question in my mind that some of those who hear me today will live to see the extension of these experiments to diabetes in man.
