Eight ounces of the chloroform were used for both the mares, 
and a cloth was tied round the upper part of the muzzle, .to prevent 
any escaping. The time was kept by a gentleman present, and I 
have no doubt of its correctness. * 
If you consider this worthy of insertion in your valuable period- 
ical, and will allow it to appear in the next number, I shall be 
obliged. 
I beg to conclude these remarks by saying, that it is, in my 
opinion, very doubtful whether chloroform will ever become an effi- 
cient agent in veterinary practice on the horse, as I believe that 
these two bad-conditioned animals suffered more in being reduced 
to a state of insensibility, and in recovering from that state, than 
they did from the operations performed. 
What would be the case with horses in first-rate condition 1 I 
do not write this by way of discouragement, it being my intention 
to take every opportunity of administering it. 
Yours, very sincerely.
