: without data regarding their ultimate composition, it would

| The yellow acid separated by amylic alcohol is of interest, 
because to its presence the tinctorial value of the drug asa 
E dye-stuff i is doubtless due. In order to obtain the-acid ina | 
_ pure state the following method was tried:—A concentrated 
"aqueous solution of the plant was precipitated with lead 
acetate, and the yellow precipitate well washed by decantation. 
_ The washed precipitate was diffused through water acidulated 
7 with hydrochloric acid, and the separated chloride of lead 
_ removed by filtration. The yellow’ solution was agitated with 
_ amylic alcohol; on evaporating off the amylic alcohol a deep 
yellowish red axtvict was obtained, easily soluble in water, and 
4 possessing a marked acid reaction. The addition of acids — 
caused the precipitation of yellow flocks, soluble on agitation; 
_ the addition of alkalies caused the liquid to assume a deep — 
yellow colour. The aqueous solution gave a dirty olive-green 
_ coloration with ferric chloride, due probably to the presence 
of a trace of tannin. The aqueous solution agitated with 
_ water acidulated with sulphuric acid in a sealed tube at 100° 
C. for some hours afforded a turbid solution, which contained 
_ dark brown ffocks, and which precipitated an alkaline solution 
of dS on bailing’
