About 64 per cent, of this oil distils below 165°, due to the presence of a large amount of pinene. Cadinene and traces of an aldehyde were also found in this oil, which has also been investigated by Eodie 9 who found that it contained over 90 per cent, of terpenes, which consisted of pinene, Z-camphene and phellandrene. Acetic and capronic acids were identified as constituents of the esters. The oil from the leaves and^twigs of Juniperus phanicea has the following characters, which will indicate the effect of its addition to the true oil of savin:— 1 Report, October, 1895, 44.
