CASES OF BILIARY OBSTRUCTION.

excised all the unhealthy portion, and dressed the wound with a 
solution of chloride of soda and tinct. myrrh; ordering cold 
mashes and gruel until my next visit. 
215^.—The wound much more healthy. Repeat the dressing. 
The mare finds much difficulty in eating. 
236?.—The wound is almost healed, and she eats better. Re¬ 
peat the dressing. 
From this time the animal continued to do well, and she 
now eats with very little difficulty, and keeps herself in good 
condition. The injury was proved to have been done by the 
brutal horse-keeper jagging the tongue against the teeth, out 
of revenge for some slight affront. 
My principal object in sending the case to you is, to add my 
humble testimony to that of your talented correspondent, Mr. 
Simpson, as to the merits of the chloride of soda ; the virtues of 
which I think, with him, vVill be more and more prized by the 
veterinary surgeon. 
TWO CASES OF BILIARY OBSTRUCTION SUCCESS¬ 
FULLY TREATED WITH THE PROTOCHLORIDE 
OF MERCURY (CALOMEL). 
By the same. 
In the middle of February last I was desired by the farming 
bailiff of his Grace the Duke of Manchester to look at an ox that 
had for a long time been in an emaciated state, and was still 
rapidly losing flesh. 
Symptoms. —Conjunctival and buccal membranes, the ears, 
horns, and skin, generally, completely tinged of a deep yel¬ 
low, and the faeces extremely hard, and quite black. These ap¬ 
pearances led me to conclude that there must be an obstruction 
existing in the biliary duct, which, from the complication existing 
in the biliary organs of cattle, leads me to believe to be much more 
frequently the cause of disease, than in the horse with his more 
simple apparatus. 
Treatment .—R Calomel 3j, in some good thick gruel, 
and repeat the medicine on the following day. I was soon con¬ 
vinced that I was right in my prognosis, for the beast began to 
rapidly amend. The yellowness all left him in a few days, and he 
continued to do well afterwards. 
CASE II. 
Dec. '7th .—A farmer came to me for something for his cow, 
stating that she had a deal of fever on her, and that he had given
