dissolved, affording a clear solution, but which became turbid on cooling 
from a deposit of yellowish flocks, which on miseroscopie 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 probably allied 
to the Querci trin 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 \vas 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. 639).
