DIABETES AND FATTY LIVER IN CANIDAE. 
Aii excessively corpulent dog had been for three days 
apparantly unwell and inactive; from the examination no i 
symptom was discovered which could not be attributed to the 
obesity. Five months later the same animal was returned, 
but in a decidedly thinner condition, which despite a continu¬ 
ously good appetite continued to diminish in gross weight. 
Thirst increased so that at this time, the relatively insignifi- , 
cant patient was consuming from one to one and a half liters of 
water per night. The act of urination was indulged in, all 
but continuously, the volition seeming no factor in the occur¬ 
rence. Since the last eight weeks imperfect sight has over¬ 
taken the subject. 
Status Praesens— Pulse 100, but no alteration in the tem¬ 
perature. In the hypochondriac region the abdomen seemed 
enlarged, and this directly referable to a hypertrophied liver, j 
which extended forward to the seventh rib, causing dullness ; 
on percussion. Cataract in each eye, but in the posterior 
chamber of the organ no change in the refracting media. 
The animal was immediately destroyed ; autopsy offering 
slight catarrh of the stomach with very well marked general 
anaemia. The liver of colossal proportions ; fatty, but with¬ 
out pathological change. 
Encephalon, kidneys and pancreas unaltered. In the blad¬ 
der a small portion of urine, which yielded abundant saccha¬ 
rine material. 
The case was one of diabetes mellitus. Since 1889 Schin- 
delka has seen but three cases of diabetes mellitus, and two 
diabetes insipidus.— CEst. Wissensckaft Ztsch. /. V. K.
