aromatic odour, but did not yield any crystalline deposit on 

 standing: in absolute alcohol it was soluble^ and on spon- 

 taneous evaporation some yellow matter separated, wbich \v^as 

 destitute of crystalline structure on microscopic examination. 

 The alcoholic solution had no special taste. The ether extract 

 was yellovr, and had an aromatic somewhat tea-like odour, and 

 on standing became indistinctly crystalline. In warm water 

 , a portion dissolved, the solution possessing a strong acid 

 reaction, and affording a dirty reddish coloration with fernc 

 chloride : it did not precipitate gelatine, and gave no reaction 

 with cyanide of potassium. The portion insoluble in water 

 was dissolved by ammonia, afPording a deep yellow coloured 

 solution with a somewhat camphoraceous odour, the addition 

 of acids causing the precipitation of whitish flocks. 



The ether extract obtained from the original aqueous solution, 

 after it had been rendered alkaline, contained a well-markea 

 alkaloidal principle, which after purification afforded tKe 

 following reactions : with Frohde's reagent pinkish in the cold, 

 dirty blue on warming ; with sulphuric acid yellowish-red ; no 

 reaction with sulphuric acid and potassium bichromate ; no 

 reaction with ferric chloiide ; with nitric acid a yellow color- 

 ation ; it was not precipitated by chromate of potash from an 

 aqueous solution acidulated with sulphuric acid; taste barsn, 

 without bitterness. We propose provisionally to call tms 

 principle AcaJyphhie. 



Ainslio notices the use of A. fruticosa, Forsk., as a 

 stomachic and alterative, an infusion of the leaves being used.
