‘ANAESTHESIA OF THE DOG’ AND CAT. 4I 
For man, Aubert has recommended the use of the following 
mixture, which contains a smaller proportion of morphine, and 
. especially of atropine :

This solution is also preferable for dogs. Half of acubic centimeter 
is an injection sufficiently large for a small-sized dog, one or two 
cubic centimeters for subjects of middle size, and three or four for 
large dogs. After 15 or 25 minutes, the chloroform is administered. 
By this process, a deep sleep of long duration is obtained—there 
is no danger of syncope. (Kaufman, Desoubry.) 
Cats are very susceptible to the various anesthetics. Administered. 
in slightly too strong doses, or too rapidly, or for too long a time, 
there is danger of death. 
A simple and easy method consists in placing the animal under 
‘a glass bell, where small sponges, or pieces of wadding, moistened 
with chloroform have been placed. Soon the patient totters and 
falls; it is taken from under the glass cover and operated upon: 
‘This manner of chloroforming is not without danger; it only 
produces short sleep, and if new inhalations are made, the animal 
may die. 
The process of Dastré and Morat is the best; but as the cat is 
extremely sensitive to the action of morphine, which produces in it 
@ very strong excitement, the dose must not be above o gram. coos 
(instead ogram. 00s) for each kilogramme. Guinard, who gives the 
methods mentioned above, has also recommended another which 
allows one to bring about a long state of narcosis. He injects 
hypodermically muriate of morphine, in doses of ogram. 005 for 
each kilogramme of the animal ; then, as soon as the phenomena of 
excitement subside (after fifteen or twenty minutes), he places the 
cat under a glass bell with a few sponges impregnated with chloro~ 
form. As soon as signs of narcosis are apparent, the animal is 
removed from the cover, and the inhalations continued a few 
moments. Anzsthesia lasting forty-five minutes can thus be obtained. 
The excitement which attended the taking of the morphine in the 
beginning reappears when the animal wakes up, and lasts some time.

The veterinarian may be called to perform some operations 
(puncture of abcesses, removal of tumors, or the extraction of the 
canines) on monkeys kept in captivity. Some of these animals are 
so easily handled that anesthesia with them is useless ; but there 
are others which are strong and dangerous, and which must be
