tissue. The walls of the urethral canal were very much 
thickened, and its interior almost closed, which will account 
for the gradual diminution of the quantity of urine passed 
at a time during the latter stages of the disease. 
Such is a brief outline of the examination made by me of 
the morbid parts, and taking a retrospective view of the 
case, I am inclined to think, as before stated, that the injury 
done to the bladder, which eventually gave rise to the 
tumour, took place during the act of parturition with her 
first calf, and although the nature of the disease did not 
prevent a second conception, nor interfere with gestation, 
still it gradually impaired her health to an extent to render 
it necessary for her to be destroyed. It is probable that 
during the second calving , which took place about two weeks 
before Mr. Kettle was called in to see her, additional exciting 
causes came into operation, which resulted in a rapid increase 
in the size of the tumour. The hsemorrhage was now greater, 
and the urethral canal became very nearly closed—changes 
which will account for the symptoms observed in the latter 
period of the animaPs life. The kidneys and ureters were 
free from structural disease.

A roan draught gelding, belonging to a railway company, 
whilst shunting, was thrown dow r n on the rails, and severely 
injured the near hock, on the inner side. At my first 
examination I was afraid there was a fracture of some of the 
bones; the limb was pendulous, and a quantity of blood, 
mingled with synovia, flowed from a small wound. I 
directed the hock to be constantly fomented with warm water 
during the day, and a linseed meal poultice to be applied at 
night, until the inflammation and tumefaction of the injured 
parts had subsided. The animal was then put in slings, for • 
he could not place his foot to the ground. The discharge 
of synovia was excessive. 
The managers of the company wished the horse to be 
destroyed, but I begged permission to try what further and 
bolder treatment might effect. This being granted, the Tin.
