The taste was very bitter, aromatic, and also somewhat terehin- 

 thmate. On treatment with ammonia the extract was partly dis- 

 solved, yielding a deep orange-red solution, which was agitated 

 with ether, the ether showing a marked greenish fluorescence. 

 On evaporating off the ether, a bright yellow, viscid, trans- 

 parent extract was left, with a bitterish taste, accompanied by a 

 strong one of turpentine. In alcoholic solution the extract was 

 neutral in reaction, the solution exhibiting a marked fluorescence. 

 The ammoniacal solution, after separation of the ether, was acidu- 

 lated with sulphuric acid and reagitated with ether. On evapora- 

 tion of the ether, a bright yellow, soft, varnish-like residue was 

 left ; on heating with water the greater part dissolved, forming a 

 clear solution which became turbid on cooling. With alkaHcs 

 the extract gave a deep orange-red solution: with ferric 

 chloride a dirty browiiish-red precipitate: with basic lead 

 acetate yellowish flocks were precipitated: with lime and baryta 

 water a yellowish coloration, but no precipitates. After 

 boiling with dilute sulphuric acid,Fehling's solution was reduced. 

 The reactions of this acid were, therefore, similar to those of the 

 yellow poicdei- which separated on agitation with petroleum ether. 

 The original solution after addition of sulphuric acid ^vas 

 rendered alkaline with ammonia and agitated with ether. On 

 spontaneous evaporation of the ether, a yellow, soft, non- 

 crystalline, transparent, varnish-Kke extract was left. This was 

 treated with a little dilute sulphuric acid, in which a portion only 

 dissolved, and agitated with ether, which removed resinous 

 nuitter. The ether was then separated, and the aqueous 

 solution rendered alkaline, and reagitated with ether. A 

 yellow non-crystalline extract was obtained, which was nearly 

 wholly soluble in dilute sulphuric acid, and which afforded the 

 lollowmg reactions : with ammonia a white precipitate soluble in 

 excess : with caustic soda a similar precipitate,only slightly soluble
