off the emulgent arteries. The opening appeared lacerated, but 
l could not trace any symptoms of previous disease. 
The mare being blind, led me to examine her eyes. I found 
in the near eye the crystalline lens of a cartilaginous texture, 
not adhering to the capsule. 
On removing the off eye, l found the posterior part very much 
pitted. The anterior chamber was filled with aqueous humour ; 
the lens was of a cartilaginous texture, and, to my surprise, the pos- 
terior chamber filled with an osseous deposit, giving the pitted 
appearance to the part. 
Not being able to account for the ruptured aorta, I am quite 
at a loss to what cause to attribute the lesion, as she had not 
been at work or irritated in the least, that I could learn ; and 
not being quite satisfied as to the osseous deposit being the cause 
or the effect of the blindness in the off eye, I should be much 
obliged to any of your readers for their opinion, not having seen 
or heard of the like before. 
The above is quite at your disposal, if you think it worth in- 
serting in your valuable Journal, which I trust will be continued 
wdth the same spirit and kind feeling as formerly. 
ON STRANGULATED HERNIA.

Light Cavalry , Madras. 
Dear Sir, — As “ Strangulated Hernia,” when it does occur in 
England, is most likely to be found among horses of great value, 
and as it is of frequent occurrence in this country among our 
cavalry horses, a decision on the following point is, I think, of 
sufficient importance to warrant my requesting you to give this 
communication a place in The Veterinarian. 
Should the testicle on the side affected be taken away by 
means of wooden clams in every case of strangulated scrotal her- 
nia? I am inclined to think that it ought in every case. It is, I 
believe, generally done when the hernia has been reduced without 
dividing the stricture; but, when the stricture has been divided, 
it is, I believe, generally supposed that, from the effects of the 
operation, the ring will be sufficiently closed, and that, conse- 
quently, there is no necessity for taking away the testicle. This, 
however, is rather doubtful, as the following case will shew : — 
About this time in 1838, Mr. Chester, the veterinary surgeon, 
operated on a horse belonging to an officer of the 8th regiment of
