Muir (ii. 187), R. Voiry (Chem. News, June 15th 1888, 
p. 241,) states that on fractional distillation cajuput oil yields a 
terpilenol, which has no action on polarized light. He further 
obtained acetic, butyric and valerianic po: mixed with a _ 
carbide boiling at 160° in a vacuum. 
The green tint of the oil is due to copper, a minute propor: 
_ tion of which metal is usually present in all that is imported. 
It may be made evident by agitating the oil with very dilute 
_ hydrochloric acid. To the acid, after it has been put into a 
platinum capsule, a little zinc should be added, when the copper 
a will be immediately deposited on the platinum. The liquid 
- may be then poured off, and the copper dissolved and tested. 
_ When the oil is rectified, it is obtained colourless, but it readily 
_ becomes green if in contact fora short time with metallic 
copper. 
| Commerce.—The oil is imported into India from Singapore 
_ in large quantities packed in common black quart bottles. 
From the official trade reports of the latter port it appears that 
India is the chief market for this article. Average value,
