admixture with turpentine (Boulez. Bull. Soc. Chim. 1907. ZF. (i) 
117), acid value 5-5. 
Preliminary examination having shown th'e presence in the oil of a 
trace of an aldehyde or ketone and of acids, a kilo of the oil was 
shaken with sodium hydrogen sulphite solution when a small quantity 
(5 grammes) of a crystalline bisulphite compoimd separated.* 
This was filtered oS, the oil well washed with dilute sodium 
hydroxide solution (see below), dried and distilled under diminished 
pressure (47mm.) when the following fractions were obtained : —

* It was not found possible to isolate the ketone or aldehyde in a pure state. 
The semicarbazone was a mixture and after repeated crystallisation a small fraction 
was obtained in fine needles melting at about 180°. It was not identified.
