A portion of the crude oil was boiled two hours with 

 acetic anhydride and sodium acetate in the usual way, and 

 the acetylated oil determined. 1*5371 gram, required 

 0*1764 gram. KOH giving 115 as the saponification number. 

 This represents 45*6 per cent, of a sesquiterpene alcohoL 

 Thus nearly half the crude oil of this sample consisted of 

 the alcohol characteristic of this species of Melaleuca. 



We are indebted to Dr. B. Daydon Jackson, f.l.s., of the 

 London Linnean Society, and Dr. M. Treub of Java, for 

 assistance and material. Also to Mr. J. H. Maiden, f.l.s.* 

 and Prof. A. J. Ewart, d.sc, for kindly permitting us to 

 examine material in the Sydney and Melbourne Herbaria 

 respectively.
