a resin oil. The oil distilling from 100° to 165° is colorless, with an orange- 
like odor; specific gravity, 37 = 0.7692; AD =437°.0. By two careful dis- 
tillations the following fractions were obtained:

Fraction No. 1 had a pleasant odor recalling oranges, and the following 4 
properties: specific gravity, "0.6831; N D 1.3898; optical rotation—0.

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. The residue ground up and distilled with steam yielded 73 cubic 
centimeters more. This oil distilled in steam contained no heptane, show- 
ing that probably all the latter is in the oil cavities immediately surround- 
ing 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 resinif- 
erous and have the same pleasant, orange-like odor as the fruits. * * * 
Pittosporum resiniferum is a tree reaching a height of 25 to 
30 meters, although in many cases it fruits when not over 6 
to 12 meters high. It has fragrant, white flowers, about 1.3 
centimeters long, which are borne in clusters on the stem. The 
leaves are smooth, pointed at both ends, and usually between 
8 and 15 centimeters in length. The fruits are about 3 cen- 
timeters long. 
This species is not very abundant in any part of the Islands, 
but is widely distributed and usually found on high mountain 
ridges.
