Black Bean (Castanospermum australe), and is equally as hard. 



ESSENTIAL OIL. — Leaves and terminal branchlets for distillation were 

 obtained from Xarrabri. N.S.W., in July, 1901. The yield of oil was 0-16 per 

 cent. The crude oil was of a dark colour, and had an odour, when diffused, 

 strongly reminding of cymene. As the characteristic oxidation product 

 cymene were obtained with the oil of E. melanophloia, it is very probable that 

 cymene is a constituent in the oil of the present specie-. Phellandrein die- 

 not occur; pinene was proved by it^ chemical combinations and reactions. A 

 small quantity of cineol was found, but not exceeding 5 to ro per cent. 

 The presence of the sesquiterpene aromadendrene was pronounced. The 

 dark colour of the oil was due to the phenols acting on the iron removed 

 from the still by the action of the free acids in the oil. The colour was readil; 

 removed by agitating the oil with .1 dilute solution of soda ; the remaining oil 

 was then nearK colourless, so thai the optical rotation could be readily taken. 

 The venation of the mature lanceolate leaves of tin- species indicate- the 

 predominance of pinene in the lower boiling terpenes, tint- being in agreement 

 with the oil- of the genus Angophora. (For the oil- of the. A ngophoras see p 

 by one of us, Proc. Roj . Soc, N.S.W., Aug. r.913.) 



I he crude oil had specific gravity at 13 C. = 0-8757; optical rotation,
