ESSENTIAL OIL. Material of this species was obtained from near Parra- 

 matta, N.S.W., and forwarded for distillation by Dr. Cuthberf Hall. The yield 



Oi Oil Was o-J per cent. 



The crude oil was almosi as viscous as castor oil, and had little resemblance 

 to the ordinary Eucalyptus oils of commerce. It contained a considerable amounl 

 of the sesquiterpene. . rid in this respect resembled the oil of E. nova-anglica 

 and a. few others. The oil at our disposal did not permit of complete analysis, 

 but it is possible thai ihe active terpene was dextro-rotatory pinene. Cineol 

 was practically absent, and phellandrene could not be detected. The oil was but 

 little coloured and had a no1 unpleasanl odour. The phenols gave the reaction 

 for tasmanol, but the crystalline phenol australol appears to be the most abundant. 



The crude oil had specific gravity at 15 C. = 0-9469; rotation a D + 4-8°; 

 refractive index at 20° = 1-4989, and was insoluble in 10 volumes 80 per cent, 

 alcohol. The saponification number for the esters and free acid was only 2, 

 so that esters were practically absent. Some of the oil was distilled, but only 

 2 per cent, cam'' over below 200° C. ; traces of cineol could be detected in this 

 portion, the remainder consisting largely of the sesquiterpene.
