It is well known that men and other animals afflicted with diabetes lose weight rapidly, despite greater appetite and increased food consumption. In the last stage of diabetes in dogs the animal shows greater emaciation than a normal dog at death from lack of tfood. Dr. Luckhardt studied the gastric tonus and hunger contractions in two diabetic dogs, and found them persisting and even augmented to within a few hours of death, when the animal is too emaciated and feeble to stand, or to masticate and swallow food. It is true that death from diabetes involves factors that are not present in the normal animal dying from starvation, but dogs dying from pancreatic deficiency have all the appearances of an animal in the most extreme state of emaciation. Nevertheless, there is no gastric atony, and the animal gives evidence of hunger and appetite in his avidity for food to within a few hours of death.
