The ash contained 18-33% soluble in water. 

 70-62% soluble in HCl. 

 11-05% insol. in HCl. 

 The entire ash was found to have the following composition, 

 and is compared with the Victorian sassafras, Atherosperma 

 moschatum, under the same conditions, from Zeyer's analysis(l). 



Bulk Extraction. 



For the more complete examination of the constituents of the 

 bark, a large quantity was next treated as in the following 

 scheme : — 



Extraction with alcohol. 



Steam distillation of the extract, yielding 



A. Volatile oil. 



B. Aqueous distillate. 



C. Insoluble resins. 



D. Alkaloid in aqueous solution. 



The air-dried bark, weighing 18 kilos., was passed through a 

 powerful disintegrator, and the powder extracted twice with hot 

 95% methylated spirit. The extract was distilled under dimin- 

 ished pressure, and in the removal of the solvent much of the 

 exceedingly volatile oil was unavoidably lost. The thick tarry 

 liquid left in the still, and measuring about one and a half litres,
