 contrivance, but Enghsh veterinarians, and among them Mr. E. 

 Cox, recommend in preference a chloroform-bag, in the form 

 of an ordinary bag, made of strong canvas, both ends of which can 

 be closed by a running string, one being tied around the nose

while the bag is secured by cords to the halter or to the straps 

 of the cap. The chloroform is introduced into the bag by means 

 of a thin j^iece of cloth saturated with the liquid. 



The chloroform nose-cap recommended by Mr. Gresswell also 

 answers a very good purpose, and in fact, possesses advantages 

 which render it superior to the apparatus of Mr. Cox. It is not 

 so portable in its form, but is more durable ia its construction. 

 In. fact, it produces the features of the ordinary stable muzzle 

 which we have already mentioned. 



The apparatus of Carlisle is also one of English invention, for 

 which great merit is claimed. We have used it, and the trial has 

 shown it to possess many features of marked superiority over the 

 others. 



The quantity of liquid required to bring a large animal under 

 complete general anesthesia cannot be positively ascertained.
