ether. Tlie etlicr extract formed a yellow varnisli indistinctly 

 crystalline in places. By the action of acidulated water traces 

 of an alkaloid were separated. The extract when acted npon 

 by cold absolute alcohol afforded a bright yellow solution with- 

 out bitter taste; the portion of the extract insoluble in cold 

 alcohol was white, by heating with alcohol it dissolved, and on 



w 



cooling white M'oolly flocks separated^ which on microscopic 



examination presented the appearance of interlaced hair -like 



masses. The amount of this principle was very small and its 



nature could not be determined. The alkaline solution of the 



original ether extract was acidulated and reagitated with ether, 



which left on separation a red transparent waxy varnish, 



insoluble in water, easilv soluble in cold absolute alcohol with 



strong acid reaction and bitter taste. This principle had the 



properties of a resin acid, and we propose terming it ^ JibanttG 



acid. The alkaline ether extract contained traces of a white 



alkaloid without bitterness, crystallizable from ether, and 



giving a faint yellow coloration with Frohde's reagent in the 



cold, deepening slightly on warming ; no reaction with nitric 



acid, ^YQ provisionally call this alkaloid Jibantine. This 



alkaloid appeared similar to tie one contained in the acid 

 ether extract. 



The chocolate-coloured flakes referred to as having separated 

 on agitation with petroleum ether, were repeatedly agitated 

 with ether, which on evaporation afforded a small amount of 

 extractive similar to the original acid ether extract. The 

 insoluble flocks were then dissolved in caustic soda and reao-i* 

 tated with ether, the ether affording a small amount of 

 extractive. The alkaline solution was rendered acid and 

 reagitated with ether, which separated a certain amount of a 

 bitter acid resin, similar to the one we have termed /3 Jibantio 

 acid, while chocolate flocks remained insoluble. 



^ Jibantic acid when freshly precipitated from an alkaline 

 solution by acids would appear to be easily soluble in ether but 

 the flocks after standing become less soluble. The chocolate 

 flocks just referred to were repeatedly agitated with ether, 

 dissolved in caustic soda, precipitated with acid, and rpjio-ifof J
