form, and a pale yellow tioge to boiling water. Under the 

 microscope it is seen to consist of stellately arranged, color- 

 less hairs, mixed with depressed-globular glands, containing 

 numerous red, club-shaped vesicles. 



Constituents. — The chief principle is (1) rottlerin, 

 (CjjaHjoOg), occurring in yellow acicular crystals, soluble in hot 

 alcohol, ether, benzol, and carbon disulphide. There are 

 also (2) resins, 80 per cent. 



Dose.—T>., 3ss.-ii. (2.-8.); H. k C, ^i. (30.). 



Action and Uses. — Kamala is an anthelmintic. It is 

 employed more frequently as a taeniacide, but will also kill 

 ascarides and oxyurides. Large doses may give rise to 

 nausea and vomitiug in dogs and cats. Kamala is also a 

 purgative, so that it is rarely necessary to employ one after 

 its administration. It should be given in syrup to the fast- 

 ing animal, and repeated in eight hours if the first dose is 

 not operative by that time.
