ESSENTIAL OIL. Material for distillation was received from Officer, 

 Victoria, in rgoo, bul as the results could nol be specifi* allj pla< ed a1 thai time 

 they were omitted in the firsl edition. On the discover} ol E Australiana, 

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

 The crude oil was but lit 1 1 » 1 oloured, and had a sei ondarj odour ol citral. It was 

 lairh rich 11 cineol and contained, at that time of the year, tra< es ol phellandrene. 

 It had specific gravity at 15° C = 0-9155; rotation t-g , refractivi index 



at 20 = 1 4662 and was soluble in 1 ! volumes 70 per cent al< ohol. The saponi 

 lit ation number for the esters a\\^\ live ;i< id was N. 



On rectification, 1 per cent, distilled below 174 C. corr. . Between 

 l 74 I,s .'i • 7 s P er cen 1 distilled, and between 183-225 [6 per cent, distilled. 

 These fractions gave the following results: 



First fraction, sp. gr. at 15° C = 0-(, 01,7; rotation a A 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. Peniold investigated the oil from this species growing 

 near Moruya, NS.W. The analysis gave results quite in agreemenl with those 

 recorded above.
