sufficiently to allow the ausesthetic to flow out in this small 

 quantity. The nostrils should be previously smeared with 

 vaseline to afford protection from the irritation of the 

 chloroform. If the operation is prolonged, anaesthesia may 

 be carried on with ether. It is not essential to cast a horse 

 before chloroformization, but the animal should be con- 

 trolled with side lines, and a twitch should be placed upon 

 the nose, unless an inhaler is used. Since there is com- 

 monly more or less struggling, it is, however, more satisfac- 

 tory to cast an animal before anaesthesia is begun. The 

 writer has given chloroform in several instances to horses 

 in the standing position until they fell or were pushed over 

 upon a straw bed, with the aid of only one assistant. In- 

 thus producing anaesthesia, a sponge covered with a towel 

 was used, and this was saturated with about half an ounce 

 of chloroform, and held at first three inches from the 

 animal's nose, in order that the vapor should be thoroughly 

 diluted with air. From half a drachm to a drachm of 

 chloroform should be added from time to time, always 

 allowing plenty of air, and inhalation may be continued for 

 an hour with comparative safety. 



The anaesthetizer should give his whole attention to the 

 work, and watch carefully the respiration, pulse and pupil, 

 for any sign of danger. If any arise, the anaesthetic should 

 be removed and treatment pursued as recommended in the 

 previous section. 



Dogs should be fasted for twelve hours before etheriza- 

 tion, in order to avoid vomiting during anaesthesia. It is 

 necessary to muzzle dogs before anaesthesia is begun. This 

 may be done by tying a strong tape about the nose, bringing 

 both ends up between the ears, over the top of the head, 

 and then tying them together in a knot, and finally carrying 

 the ends down, one on either side of the neck, and fastening 

 them underneath. A wire muzzle may be used to control 

 the dog more conveniently, and the ether is then poured 

 upon a sponge within the muzzle and the muzzle is covered 

 with cloth to keep out the air. If the extemporaneous tape
