It is worthy of remark how closely the refractive indices 

 of the three samples of the crude oil agree, and this is also 

 the case with their specific gravities; the lower figure of 

 the May sample is perhaps indicative of a high specific 

 gravity for the ester, as well as of the presence of a slightly 

 larger amount of phellandretie, also -niggr st.-d by the higher 



The Phenol.— 200 cc. of the March distillate were agi- 

 tated with a 5f solution of NaOH, until the phenol and free 

 acid were removed. The aqueous portion, with washings, 

 was then treated with ether to remove adhering oil, '.he 

 ether dispelled by heating, and the solution acidified. The 

 phenol and acid thus separated were removed by ether, 

 and when this had evaporated the residue became crystal- 

 line, due to the presence of the free acid. It was again 

 dissolved in ether, the ethereal solution agitated with an 

 aqueous solution of carbonate of soda, iu which the acid 

 readily dissolved, leaving the phenol in the ether. The 

 aqueous portion was washed with fresh ether, and the 

 ethereal solutions evaporated to dryness. The phenol 



coloured liquid, and had a marked clove odour. When dis- 

 solved in alcohol the blue colour reaction for eugenol with 

 ferric chloride was not at all distinctive, the colour being 

 rather an intense green to bluish-green. This coloration 

 suggested the presence of the isomeric form, chavibetol,
