Five ces. of the oil were extracted in turn with sodium 
bisulphite and with sodium hydroxide solutions. Absorp- 
tion to the extent of about 1 per cent. of an aldehydic body 
and -5 per cent. of a phenolic body giving a greenish colour 
with ferric chloride were recorded. 
On fractionation of 370 ces. of the oil at 2 mms. 
pressure, using an oil pump with a trap cooled in liquid 
ammonia interposed between the pump and receiver, there 
were collected—

The presence of cineol was indicated in the lower 
fractions by its odour, and fractions (2), (3), (4), (5), and 
(6) were accordingly extracted several times with 50 per 
cent. resorein solution. 
The unabsorbed oil in these fractions was then refrac- 
tionated at 21 mms. pressure, and the following fractions 
ultimately colleeted :—

d-Finene.—The physical constants as well as the odour 
of fraction (9) suggested the presence of pinene, although 
the presence of phellandrene was also indicated by the 
nitrosite reaction. It did not, however, yield the nitrosyl 
chloride characteristic of pinene (owing, no doubt, to its 
high degree of optical activity), but the presence of pinene 
was confirmed by oxidation with potassium permanganate 
solution. 
Five ces. of the oil were shaken with 10 grammes of 
potassium permanganate and 150 ees. of water and 100
