Following this preliminary examination, a proximate analysis ofthe ground plant was made according to Dragcndorffs scheme,with the results hereinafter stated. Petroleum ether removed 1-56 per cent, of extractive matter con-sisting of o-13 per cent, of caoutchouc, 048 per cent, of wax and 0-95per cent, of fat. Ether, , 1890, extracted 1-24 per cent, of the weight of theground plant; 14-54 per cent, of this extract was soluble in ^^-^/ Fig. 2. The aqueous solution had an acid reaction toward litmus paper ; itreacted as follows: Calcium hydrate produced a copious, reddish, flocculent precipi-tate. Both normal and basic lead acetate gave precipitates of the samekind as caused by calcium hydrate. Ammoniacal silver nitrate solution was reduced on the applica-tion of heat. Gold chloride solution was also reduced when heatwas applied. Fehlings solution was reduced by the plain filtrate upon warm- Am. Jour.

A portion of the solution which gave these reactions was acidi-fied with diluted sulphuric acid, placed in a separating funnel, and
