AGETANILID 301 



canine distemper, spasmodic cough, rigidity of the uterine 

 OS in the first stage of labor, hysteria, tetanus, and strych- 

 nine poisoning. In spasmodic colic, chloral is inferior to 

 opium as an anodyne, but has the advantage of not inducing 

 constipation. It may be employed in colic, by the rectum, 

 combined with morphine given under the skin, as recom- 

 mended for procuring anaesthesia. It is the best remedy we 

 possess for the treatment of convulsions in dogs, apart from 

 anaesthetics. Ether may be administered during the con- 

 vulsion, and chloral given simultaneously, or between the 

 attacks, in gr.v.-xx., per rectum, and repeated if necessary. 

 Chloral is only indicated in chorea when the movements are 

 so severe that the animal cannot secure sleep or rest. In 

 distemper in dogs, chloral is used for the same purpose, 

 when there is excessive congh and restlessness. • Chloral is 

 given per rectum in tetanus, so as to keep the animal conti- 

 nually narcotized, and may be employed in conjunction with 

 tetanus antitoxine. 



Spasm of the os uteri is relieved by chloral when given 

 per rectum in frequently repeated doses, until the safe 

 physiological limit is reached. Chloral is inferior to ether 

 or chloroform as an anaesthetic, because it is not so safe, nor 

 is the aDsesthesia so complete, but it relieves pain effectually, 

 and is more easily administered. It is combined, in order 

 to produce anaesthesia, with small doses of morphine, which 

 decidedly enhance the anodyne action of chloral. 



To prepare a horse for surgical operation, 3 grains of 

 morphine sulphate and 1 grain of atropine sulphate may be 

 injected under the skin, and followed in 10 minutes by 

 an ^nema containing 1 ounce of chloral.
