240 INORGANIC AGENTS 



Chlorali hydrati 5h- 



Acaciae Si- 

 Aquae ad Ovi. 



M. 



S. Give per rectum to horse as an anesthetic. 



The same dose may be given to cattle as an anesthetic before opera- 

 tion. Chloral narcosis lasts 1 or 2 hours and may be given before casting 

 to facilitate the act or to aid in the shoeing of vicious horses. The nar- 

 cosis is not deep but suflScient for most operations. 



Chloral (H., 3ss-i; D., 3ss-ii, in 10% solution) injected into the 

 peritoneal cavity will produce surgical anesthesia and has been used in 

 colic in horses with barium chloride by mouth. In flatulent colic, first 

 puncture to allow escape of gas. This treatment does not commend itself 

 to the author as a safe procedure. 



The writer has found the intraperitoneal method generally safe and 

 efficient in laparotomies in dogs but occasionally inefficient, and deaths 

 have occurred from over-dose and peritopitis. The morphine and drop- 

 ether anesthesia is safer and more satisfactory in dogs. 



Class 5. — ^Antipyretics and Analgesics. 



Chlohetoxe. CCl3(CH3)2COH. (Non-official.) 



Chloretone occurs in colorless crystals of camphoraceous odor and bitter 

 taste. It is very slightly soluble in water, soluble in alcohol and in 10 parts of 

 glycerin. It may be made from acetone, chloroform and an alkali. 



It is allied to chloral and represents it in action but does not depress the 

 heart and respiration in any ordinary doses and is an actual sedative to the 

 stomach. Externally it is an antiseptic and local anesthetic although there may 

 be some temporary burning produced by it on raw surfaces. 



It may be used also as a local anesthetic injected in 1 per cent, solution 

 (alcohol, 15 parts, water, 85 parts). Chloretone is employed with an equal amount 

 of boric acid (Borochloretone) as an application to wounds and ulcers as an 

 antiseptic and local anesthetic. 



Internally the drug is administered in human practice before operations to 

 prevent the vomiting subsequent to general anesthesia and its use is advised for 

 the same purpose in dogs and also to quiet the animals for local anesthesia. 

 Unless there is some specific reason why vomiting should not occur the sub- 

 cutaneous injection of morphine is more efficacious to aid the action of either 

 local or general anesthetics. 



Chorea and convulsion in dogs may be treated to advantage with the drug. 



It may be administered to dogs in pills or capsules.

AcETANiLiDUM. Acctanilid. CsH^O N. (U. S. & B. P.) 



Synonym. — Phenylacetamide, antifebrin. 



An acetyl derivative of aniline. 



Derivation. — Glacial acetic acid and aniline are distilled together, and the 

 residue is purified by repeated crystallization. H CiHsOj+CbHjN H2 = C8HbO 

 N+H^O. 



Properties. — Colorless, shining, micaceous crystalline laminae, or a crystalline 

 powder, odorless, having a faintly burning taste; permanent in the air. Soluble 

 in 190 parts of water, and in 3.4 parts of alcohol; also soluble in 17 parts of 

 ether, and in 8.7 parts of chloroform. 



Dose.—H., 3ii-iv, (2-16); Sh. & Sw., 3ss-i, (2-4); D., gr.iii-vii, (.2-.6).
