LAMENESS AND POLL-EVIL CAUSED BY ENTOZOA.

Application of Chloroform to Animals. 
An interesting and most successful experiment with this bene- 
ficent agent was tried on a lame horse, belonging to Mr. Reid, 
Drem, East Lothian. Dr. Robertson and Mr. F. Imlach, from 
Edinburgh, Dr. Lorimer, from Haddington, and others were present. 
About two ounces of the chloroform were poured on a piece of 
flannel cloth, below which was a sponge, the whole being placed in 
a tin case, which was tied over the horse’s nose, and surrounded 
with a flannel bag. In three minutes and a half the animal fell 
over, and in five minutes it w'as perfectly insensible. When in 
that condition, Mr. Cockburn, veterinary surgeon, Haddington, 
performed the usually painful operation of cutting the nerves of 
sensation in both of its fore feet. On cutting the second nerve the 
poor beast made a slight movement, shewing the chloroform was 
beginning to lose its effect ; but a second application of another 
ounce allowed the other two remaining nerves to be cut without a 
quiver. In twenty-five minutes from the commencement the 
animal was again on its legs, now perfectly sound. 
AN UNUSUAL KIND OF LAMENESS AND POLL-EVIL 
CAUSED BY ENTOZOA. 
By F. P. Vincent, M.R.CV.S., Devizes. 
AN unusual kind of lameness having fallen under my observa- 
tion, I take the liberty of detailing the case for the pages of The 
Veterinarian. I must apologize for the somewhat decomposed 
state of the accompanying perforans tendon. 
Aug. 20 th, 1845. — Mr. S. Akerman, a large farmer of Patney, 
near this town, applied to me respecting the lameness of a grey 
colt, of the cart-horse breed, rising three years. It appeared to be 
a sprain of the flexor tendons, about two or three inches above the 
fetlock joint. As the colt was at grass in a water meadow in 
which there were many drains, it was considered likely to have 
been caused in crossing one of them. He was taken up, bled 
locally, physicked, & c. Some time subsequently the liquid blister 
was put on, and repeated two or three times at proper intervals, 
and the animal became free from lameness.
