dissolved, affording a clear solution, but which became turbid on cooling 

 from a deposit of yellowish flocks, which on miscroscopic examination were 

 not found to exhibit a crystalline structure ; we only detected minute 

 globules. The aqueous solution was strongly acid in reaction, and gave with 

 ferric chhloride a dirty greenish coloration, with lime water a bright yellow 

 coloration, and with basic acetate of lead a sulphur-yellow precipitate. This 

 principle, soluble in water, and reprecipitated on cooling, is probablj- allied 

 to the Quereitrin group of principles, That portion of the residue insoluble 

 in water, was in properties similar to the resin dissolved by benzole. 



The aqueous acid solution was lastly rendered alkaline and agitated with 

 ether. The ethereal extract was not more than a trace, but afforded all the 

 reactions in a marked degree of an alkaloidal principle. 



The leaves also afforded marked evidence of the presence of an alkaloidal 

 principle soluble in ether, and probably similar to the one we detected in 

 the roots. (Pharmaeographia Indica, II. 539).
