V\\^tw.\ July. mm. after the liqual under investigation with acid, a greaterreduction ol Fehlings solution occurred. Neither ether nor chloroform removed anything from the acidifiedaqueous solution with which they had been agitated. The acidifiedaqueous solution was then rendered alkaline with ammoniumhydrate, and again agitated in a separating funnel with benzinether and chloroform, as previously described. The benzin oncemore removed a small amount of reddish substance, which dissolved. Fig. water and reacted with Fehlings solution, as did the substanceremoved by benzin from the acid solution. Gold and silver saltswere not reduced by this substance either. The treatment withether removed some substance having the same character as thatmaterial taken out by benzin. .Maj-ers reagent and potassium tri-lodide gave no evidence of alkaloids in the substances extractedfrom the alkaline aqueous solution.

This solvent dissolved 67-69 percent, of the extract, leavincj 1777 P^r cent, of insoluble alcoholic solution gave the following evidence of resinous mat-ter; the addition of water caused the precipitation of greenish resin-ous substance; alcoholic solution of ferric chloride gave a darkgreen color; alcoholic solution of lead acetate produced a greenflocculent precipitate.
