Residue of the original oil The residue 

 which remained in the flask on the rectification 

 by distillation with steam was separated from the 

 water by a separating funnel and allowed to stand 

 ntil the emulsion layer and presumably impurities 

 carried over from the original distillation had 

 settled. This left a yellow oil, thicker than the 

 original oil s.s obtained from the still and with 

 nearly the same odor. This oil was filtered through 

 cotton, coming through perfectly clear. On heating 

 it was found to contain a large percentage of 

 water. Granulated calcium chloride was added and 

 the oil allowed to stand two days with occasion 1 

 shaking. A considerable amount of water separated 

 out below the oil. An attempt was then made to 

 distill the oil. This was a total failure under 



Lospi-eric pressure. Decomposition (and prob- 

 ably formation of resins) occurred before any 

 vapor passed over. The quantity of unheated oil 

 on hand was not sufficient for a distillation 

 under reduced pressure and that is also deferred
