1 cc. were obtained ; t hex* were all separated as .an- t'i ;i.-; ion 

 equal to Hf of the total oil. The 5 cc. left in the still were 

 taken as remainder. 100 cc. of the oil from the Port Mac- 

 quarie material was similarly distilled, with nearly corres- 

 ponding results, although with the large fraction only 90f 

 distilled below 195° C. 



The distilled oil from both these samples was water white 

 and had an odour closely resembling those Eucalptus oils 

 richest in cineol. The small amount of water which came 

 over with the first few drops was slightly acid, and the 

 odour of the lower boiling aldehydes was detected, although 

 this was not very pronounced, nor was it very objectionable. 

 The aldehyde reactions were also readily obtained. The 

 large fractious -rave the following results: —

The reactions for cineol were most marked, the ph. .spliori. 

 acid compound becoming quite dry and powdery. The 

 quantitative determination of the cineol was made by the 

 resorcinol method, with the oil distilling between 173 - 195' 

 (\, and calculated for the whole oil ; with the Gladstone 

 sample the cineol in the whole crude oil was 81 f by this 

 method, and in the Port Macquarie oil it was 80^. The 

 specific gravity of the residue in the still, of the Gladstone 

 sample, was O'DiiO 1, and it had a refractive index 1*4924^ 

 The specific gravity <>\' the residue of the Port Macquarh- 

 . . 1 1 was 0-9:578, and the refractive iudex 1*492 at 20 C. 



In the determination of ester in the Gladstone oil with 

 boiling alcoholic potash, 3*932 gram required 0*0084 gram 

 KOH, or saponification number 2*1. With the residue 1*538 

 gram required 0*0126 gram KOH or S.N. 8*2. The crude 

 oil of the Port Macquarie sample gave S.N. 2*8. The amount
