Tlie yield was poor, 20 g. of the fraction giving only 3'8 g. 

 of nitrosocliloride. 



The benzylamide was prepared by digesting 37 g. of the 

 nitrosochloride with 4 g. of benzylamide in 30 cc. of spirit for 

 one hour on the water bath, the greater part of the spirit being 

 then distilled off and the residue poured into water; the pre- 

 cipitated oil slowly solidified, and when crystallization was 

 complete it was recrystallized from somewhat dilute alcohol ; 

 it then melted at 122°- 123° C. To the extent of 85-90 per 

 cent., therefore, the oil consists of pinene, the laero variety 

 predominating. 



The remaining fractions were too small for systematic 

 examination, but fraction 2 also seemed to consist largely of 

 pinene; limonene, if not absent, was present in very small 

 quantity only. 



Fraction 5 contained large amounts of esters, and an 

 attempt was made to characterize the alcohols present after 

 saponification, but without success; geronial was almost cer- 

 tainly absent, and although the smell of borneol was prominent 

 a specimen of that substance could not be isolated. 



In conclusion, I have to thank Miss Collins for the pre- 

 liminary botanical exmination of the fruits, and Mr. Maiden 

 for tile final identificatioii of the tree as C . verrucosa.
