REVIEW.

junior, laid before the President a communication he had re- 
ceived from Messrs. Verrier, veterinary surgeon at Rouen, and 
Girardin, Professor of Chemistry in the same town, comprising 
a MS. Memoir 
On the comparative Effects of JEther and Chloroform, in the 
Horse, the Dog, and the Cat. 
The conclusions come to in this paper are, — 
1. That the action of chloroform is much more marked than 
that of aether. 
2. That both of these agents impress rather the nervous 
centre of animal than that of organic life ; and 
3. That, contrary to the opinions of Amussat and Gruby, the 
blood undergoes the same alteration it does in asphyxia under 
the influence of aether. 
Remedy for Mange in Dogs. 
At the same sitting, it was noticed to the President that the 
communication which M. Prange, veterinary surgeon to the 
8th Regiment of Hussars, had addressed to the Society on the 
therapeutic properties of a medicine used by him with success 
for the mange in dogs, had been submitted to a committee, who 
had reported upon it as follows : — 
M. Prange has given the name to his remedy of oleo- sulphur e- 
tannique. This is the formula for it : — 
Nut oil ( Huile de Noix) 
Sulphur (Soufre Sublime ) 
Gall-nut powdered ( Noix de galle pulverisee ) 
Hemp-seed oil (Vhuile de chenevis) may be substituted for 
the nut oil, though the latter is to be preferred. 
Make the oil so hot that the finger no longer can be borne in 
it ; scatter the sulphur in it by little and little, agitating it all 
the while with a wooden spatula, to prevent the mixture be- 
coming lumpy at bottom; then add the powdered gall-nut a little 
at a time, maintain the mixture for half an hour at the same 
temperature, remove it from the fire, and it is ready for use. 
This quantity is sufficient for a dog of ordinary size. If many 
require rubbing, the quantity must be augmented accordingly. 
In using the liniment, we must provide ourselves with a stick, 
around one end of which a piece of woollen rag is wrapped, for 
the purpose of being dipped in the mixture, still maintained at 
the temperature of from 50 to 60 degrees. Two persons will be 
required to hold the dog, one seizing him by the head while the 
other holds him by the tail. The operator then, with his mop 
dipped in the liniment, vigorously scrubs him for three or four
