Condiluents, — Numerous analyses have been made of this plant with- 

 out, however, yielding any very satisfactory result when considered froia 

 n therapeutic standpoint. In addition to the common plant constituents 

 lil;e starch, gum, tannic and gallic acids, mineral salts, etc., a small pro- 

 portion of volatile oil, having the peculiar odor of the fresh drug, was de- 

 tected by one analyst, besides two resins of different character. Another 

 analyst found no volatile oil, but isolated a crystalline substance, probably 

 a neutral principle, whose alcoholic solution has an intensely acrid taste. 

 That the fresh drug po.ssesses some active volatile i)rincip]e would seem 

 probable from the fact that it certainly deteriorates by keeping, and all
