white, oval, and averages 7.2 grams in weight. The 

 sample here described would appear somewhat larger 

 than those elsewhere reported. Examination of the ground 

 kernel showed a moisture content of 21.7 per cent., and 

 of oil extracted by low boiling-point petrol of 54.7 per 

 cent. 



The oil is viscous, yellow in colour with a slight greenish 

 tinge, and of sUght bitter taste and faint aromatic odour- 

 A bulk extraction was made by compression in a screw 

 press, and a quantity of oil obtained possessing a deep 

 blue colour and depositing some amount of crystalline 

 substance on standing. 



The blue colour given bj' Callophyllum oils by contact 

 with iron has already been noticed (Bull. Imp. Inst. loc. cit.),. 

 and was due in the present case to use of an iron press. 

 The blue colouration was also obtained by treatment with 

 a small amount of alcoholic ferric chloride and is ascribable 

 to the presence of a resino-tannol hereafter noticed. The 

 deposited crystals were ascertained to be stearic acid.
