The problem of assembly the expanding nutrients wishes of a turning out to be inhabitants calls for optimal productiveness from usual and controlled ecosystems, which has now not hitherto looked to be suitable with the upkeep of environmental caliber.

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.
