DIABETES MELLITUS IN DOGS.

(Concluded from page 332.) 
Case No. 3 .—White poodle, male, 10 years of age, brought 
to the institution for humane destruction, which was speedily 
carried out by intra-thoracic injection of hydrocyanic acid. No 
history whatever could be obtained, but, owing to the extremely 
fat condition, accompanied by perfect bilateral cataracts, a small 
quantity of the urine was obtained and tested, and according to 
Trommer’s method, yielded sugar in abundance. The fermen¬ 
tation estimates indicated nearly 9 per cent, of grape sugar 
present. Owing to the hour and to the fact that such animals 
as are not officially entered as inner patients are not examined 
in the Pathological Institute, I had the opportunity to witness a 
somewhat rapid but instructive examination, conducted by one 
of the assistants. The entire viscera appeared by gaslight to 
be in a healthy condition. The kidneys especially seemed to 
be in a remarkably good state, considering the kind of patient 
and the age. On most thorough microscopic examination of 
the pancreas, liver and kidneys by my American friend, Dr. T. 
Klingmann, of Virchow’s kabratorium, and myself, we found 
the liver to be fatty metamorphosed and especially at that part 
of the aceni lying toward the venae centralis, the cells being in 
great part obliterated; kidneys normal. The pancreas was 
shrunken in its histological elements, and was in various parts 
fatty infiltrated and in others fatty metamorphosed. The neu- 
cleoli were for the greater part obliterated and dense fibrous 
tissues penetrated the aceni in various directions. 
Case No. 6. —Male, 10 years old, white terrier, was presented 
at the polyclinic for small animals, June 5, 1896 (same day as 
case No. 5 came under observation), with this history : He had 
always enjoyed good health until about three weeks ago, when 
he suddenly developed blindness in both eyes, and had shown 
great exhaustion in moderate exercise during warm weather, 
and drank inordinate quantities of water, passing urine more
