ESSENTIAL OIL. Material lor distillation was forwarded from Western 

 Australia in June, 11)04. It was collected at Narrogin, on the Great Southern 

 Railway, and consisted of leaves and terminal branchlets collected as tor com- 

 mercial distillation. The yield of oil was 0-95 per cent. The crude oil was 

 reddish in colour and had an odour resembling the cineol-pinene oils generally, 

 with a secondary one indicating aromadendral. Pinene was Eoundin some quantitj . 

 and it belonged principally to the dextro-rotatory form ; phellandrene was absent. 

 More than a third of the oil consisted of cincol, and a large amount ot the ses- 

 quiterpene was also present. The higher boiling constituents were in su< h 

 quantity that only 75 per cent, of the oil distilled below 183°. The esters were 

 small in amount, and the volatile aldehydes not at all pronounced. The 

 presence of aromadendral, together with other characters, suggest that the 

 species approaches somewhat closely the -roup of typical " Boxes," such as 

 E. hemiphloia, &c. 



The oil of this species has no special properties, and at present has little 

 value for commercial purposes. 



The crude oil had specific gravity at 15 C. = 0-9135; rotation a D + 9-0°; 

 refractive index at 20 = 1-4717, and was soluble in 1 volume 80 per cent, alcohol. 

 The saponification number for the esters and free acid was 2-5. 



On rectification, 1 per cent, distilled below 165 C. (corr.). Between 

 165-172°, 44 per cent, distilled; between 172-183 , 30 per cent, came over; 

 between r.83-228 , io per cent, distilled, and between 228-264°, ro per tent. 

 distilled. These tractions gave the following result- : 



First fraction, sp. gr. at 15 C. = 0-8981 ; rotation a + 17-7°. 

 Second ,, ,, ,, 0-9134; .. + 8-2°. 



Third ,, „ ., = o-g 129 , ,, 3-2°. 



Fourth ,, ,, ., 9 11.5 ; .. not taken. 



The Isvo-rotation shown by the third fraction, was due to the aroma- 

 dendral. 



The < ineol was determined by the phosphoric acid method ; the result was 

 36 per cent. O.M. 



The results obtained with the oil of this species were published by us in 

 the Pharmaceutical Journal. London. September, 1905.
