I saw him in conversation with Mr. Spooner. Presently he returned, 
and said, “ We decline admitting you — you cannot be present;” 
and, addressing the person who first spoke to me, said, “ He can’t go 
in, he must withdraw and I was then required to withdraw, the 
person whom Mr. Sewell addressed walking with me to the gate. 
I am, therefore, prevented forwarding you any report.

Effects of Chloroform on Animals. 
[Such is the title of a communication read by Professor Thier- 
nesse to the Academy of Medicine of Belgium, at their Sitting of 
the 1st of April last, and from which the following are extracts : — ] 
The moment surgeons, last year, commenced putting into 
practice the precious discovery of Mr. Jackson relative to the 
anaesthetic powers of inhalations of the vapour of sulphuric ether 
on the respiratory passages, I made a vast number of experiments 
on divers animals, with the view of ascertaining the action and 
effects of ethereal inhalations, and of ascertaining if it were possi- 
ble and profitable to introduce the same into veterinary surgery. 
By these experiments I hoped to have thrown light upon the 
leading questions concerning the influence of this chemical agent 
on the nervous system, the muscles, the blood, &c., as well as to 
have demonstrated its innocuity in the operative medicine of 
domestic animals. 
***** 
In imitation of the learned Professor of Edinburgh, most of the 
French surgeons prefer, now, chloroform to ether, on account of the 
promptitude of its action, as well as for the great facility it offers 
for inhalation. I shall, therefore, commence with the phenomena 
generally observed on animals submitted to inhalations of chloro- 
form. 
During the first inspirations of air charged with this chemical 
agent, animals are always calm, breathing regularly. Soon, how- 
ever, they become agitated, while saliva flows from the mouth, 
the pupil grows dilated, the pulse accelerated, then much retarded,
