ESSENTIAL OIL. Leaves and terminal branchlets for distillation were 

 obtained from Belmore, N.S.W., in September, 1900. The yield oi oil was 0-58 

 per cmt. The crude oil was reddish-brown in colour, and had a somewhat rank 

 odour, with a secondary one oi aromadendral. It contained some pinene, but 

 phellandrene was absent at this time of the year. Cineol was present, but only 

 about 15 per cent, in the crude oil. Aromadendral occurs in quantity, and it 

 was from this oil that the pure substance was first prepared for research. 

 The esters were not pronounced. Little difference in the constitution of the oils 

 from tin- species, /:'. albens, and K. Wuul/siiiiia was observed. 



rhe crude oil had specific gravity at 15 ° C. = 0-9117; rotation <z D -6-85°; 

 refractive ind< \ at 20 = 1-4853, and was soluble in _' volumes 70 per cent. 

 alcohol. Tlii saponification number for the esters and free acid was 5-8. 



On rectification, 2 per cent, distilled below 168 C. (corr. . Between 168- 

 183 , 74 percent, distilled ; between 183-2 14°, 13 per cent, came over, and between 

 2J 1 230°, 6 per cent, distilled. These fractions gave the following results.: 



First fraction, sp. gr. at 15 C. = 0-9041 ; rotation a D 3-2°. 



Sei ond ,, ,. ,, = 0-9122 ; ,, 10-3°. 



Third ., ,, .. = 0-1)424 ; „ 24-9 . 



rhe cineol, determined by the phosphoric acid method in the first fraction, 

 was 24 per cent., indicating about [8 per cent, in the crude oil O.M. . 



Material had previously been obtained from Emu Plain--, N.S.W., in 

 September, 1899; the oil was practically indentical with the above. It was, in 

 fact, alter the investigation of this sample thai it was decided to obtain 

 sufficient oil oi this species for the preparation oi aromadendral, in order thai 

 its < hemistrj might be determined. 



Ilh abo e samples were mixed together and stored in the dark, and in 

 September, 1919, the oil was again analysed. Not much alteration had taken 

 place in the oil during the nineteen years it had been kept, excepl thai it had 

 perhaps increased a little n cineol. 74 per cent, distilled below k,o° C. Mm 

 crude oil and the rectified portion gave the following results : 



Crude oil, sp. gr. ai 15 C. 0-9166; rotation a D 5-5 ; refractive index 



at 20 = P4859. 

 Rectified portion ,, = 0-8933; rotation a 7-5 ; refractive index
