Fraction No. 1 had a pleasant odor recalling oranges, and the following jirop- 



erties: specific gravity, -^^ =0.6831; N '-"- = 1.3898; optical rotation=0. 



Fraction No. 7 had a turpentine-like odor. Specific gravity, _ _ =0.8263,

The properties of fraction No. 1 leave little doubt of the identity of 



this compound with normal heptane. 



A second lot of petroleum nuts was obtained in December, 1908, from one of 



the upper ridges of Mount Mariveles, Bataan Province. One tree gave 15 kilos 



of fruits, which by pressure yielded 800 cubic centimeters of oil. Tlie residue 



ground up and distilled with steam yielded 73 cubic centimeters more, lliis oil 



distilled in steam contained no lieptane, showing that probably all the latter is in 



the oil cavities immediately surrounding the seeds, and that the pulp of the fruit 



contains only resins' and the higher boiling portions of the oil. It was also noted 



that the leaves, branches, bark, wood, and in fact, all parts of the tree are distinctly 



resiniferous and have the same pleasant, orange-like odor as the fruits. The 



united 873 cubic centimeters of crude oil were slowly distilled at ordinary pressure 



■ giving the following fractions :

Destructive distillation began above 160°, the temperature of the 

 vapor being from 170° to 240°. The color of the resin oil became con- 

 tinuously darker as the distillation proceeded until near its close, when 

 a light colored oil was collected and the temperature of the vapor fell 

 coincident with a very hot liquid below. The raw oil thus obtained 

 had a light brown color and quite a pleasant odor; specific gravity, 



^=0.978; N^^=1.4790; acid number=263. The neutral oil is

especially pleasant in odor, recalling that of menthol, although I failed 



to find this compound. 



Thirty kilos of fruits fi-om Baguio, Benguet (December, 1908), were ground 

 and distilled with steam without preliminary treatment with the hydraulic press.
