the velvety tissue, or in the scraping of the bone ; the animal lay 
still until about 8 a. m. the following morning, and the stableman 
said he had a fine rest. He made a good recovery. 
Case No. 5. 
December 9th, 1879.—A bay mare on which I was to perform 
the operation of ovariotomy. At 2:30 p.m., gave chloral hydrate 
3 vi in a ball ; at 3 p. m. I operated, and did not have any strain¬

operation, and evinced no pain, the pulse only increasing to fifty 
the following day, and the temperature rising to one hundred and 
two. 
December 11th.—The pulse was sixty, temperature, 103 ; ap¬ 
parently in no pain. I gave tincture of opium in £ oz. doses 
every four hours. The next day I myself was taken sick, and have 
not seen or heard from this animal since. 
This, gentlemen, is my success in some few cases where I have 
used chloral hydrate as an anaesthetic in operations. Hoping they 
may be of some interest, and, as we have nothing else we can use 
so readily, that they may bring forth remarks or criticisms on the 
subject from the members present, I will be glad if by present¬ 
ing them to you I have succeeded in inducing some of you to try 
it and to give publication of the results obtained.

owner called it, “ could not calf.” On my arrival I found a fine 
young black cow which was to have her first calf; by introducing
