490 DISEASES OF THE URINARY ORGANS. 



was brown and flabby, it had lost its normal texture. (Re- 

 mark.) " In most subjects djdng of this kind of the disease, 

 it is usual to find the hemorrhage proceeding from that 

 kidney least affected with the disease externally, and also, 

 to find but one kidney ulcerated internally. The staling of 

 blood is the first symptom noticed.^' 



Oct. 1829. An old black mare had been for some time 

 falling off in condition and appetite, though suffering no 

 pain, and was galloped without affecting her breathing; 

 after much riding, however, she went weakly behind ; and 

 in the stable, after staling, she voided a small quantity of 

 pus with blood. Examination ;;errec^z«m, discovered a large 

 tumour near the left kidney, extending back to the groin. 

 On the 3d Feb., 1840, the mare died from superpurgation ; 

 the intestines had the " deeply discoloured appearance, with 

 congestion of the capillaries, without thickening, which is 

 usual in hypercatharsis. The left kidney (the tumour felt) 

 was greatly enlarged, and contained much pus in schirrous 

 cysts.' 



DIABETES. 



The term is here restricted iu its meaning to denote that 

 kind or form of disease in which sugar is found to be present 

 in the urine, at the same time that the urine is — for it 

 generally is — existing in much greater quantity than in 

 health. I have some recollections of having witnessed a 

 case of diabetes while a pupil at the Veterinary College, 

 and of sugar being detected in the urine ; but having made 

 no notes at the time, I am now left in doubt about it. No 

 English author, nor French one whom I know, gives any 

 account of the disease that can be relied upon as a test of 

 its having come actually under observation in practice. 

 Some well-authenticated case of it — should such occur — 

 would really prove a boon in hippopathology. 



" In no disease is chemical science likely to prove so useful 

 as in diabetes. Willis was the first to perceive the sweet
