DIABETES MELLITUS IN DOGS. 
551 
fat, weight about 18 lbs., property of Frau Haymaun, 23 
Friedrich Street, Berlin, presented in Polyclinic for small ani¬ 
mals, April 3, 1896, with the following history : That he caused 
annoyance by incontinence of urine (probably only polyuria), 
and was losing flesh, although he was taking great quantities 
of food and water. The examination revealed the presence of 
diabetes mellitus and poisoning was recommended, and autopsy 
asked for, both being refused. During the past July I sought

hunger became excessive, diarrhoea was also seen ; polyuria and 
evident inability to retain urine beyond a very short time. 
Emaciation increased, and it was at this point that he was pre¬

failed rapidly. While very much inclined to sleep, at no time 
was there a state approaching coma. Suddenly he was seized 
with what appeared to have been convulsions and crying loudly 
fell and was unable to use the posterior extremities. Although 
treated by a private veterinarian and somewhat relieved for a 
few hours, he soon began to cry again and was chloroformed
