ESSENTIAL OIL. Material for distillation was received from Officer, 

 Victoria, in 1900, but as the results could not be specifically placed at that time 

 they were omitted in the first edition. On the discovery of E Austra'.iana, 

 however, they fall into line, and are now published. The yield of oil was 2 per cent. 

 The crude oil was but little coloured, and had a secondary odour of citral. It was 

 fairly rich in cineol and contained, at that time of the year, traces of phellandrene. 

 It had specific gravity at 15 C. = 0-9155 ; rotation a D -- 1-9; refractive index 

 at 20 i 4662 and was soluble in i volumes 70 per cent, alcohol. The saponi- 

 fication number for the esters and free acid was 8. 



On rectification, i per cent, distilled below 174 C. (corr.). Between 

 174-183, 78 per cent distilled, and between 183-225, 16 per cent, distilled. 

 These fractions gave the following results : 



First fraction, sp. gr. at 15 C = 0-9097; rotation a D -- 2-5. 

 Second ,, ,, ,, = 0-9187; ,, - 0-8. 



The cineol, determined in the crude oil by the phosphoric acid method, 

 was 50 per cent. (O.M.). 



In 1917 Mr. A. R. Penfold investigated the oil from this species growing 

 near Moruya, N S.W. The analysis gave results quite in agreement with those 

 recorded above.
