and, although volatile, of oily consistence. It inflames with great 
difficulty and, like all essential oils, has a powerful antiseptic and 
disinfectant action. Its peculiar power of dissolving resins of all 
kinds, as well as india-rubber, gives it the power of making var- 
nishes smooth and flexible without seriously injuring their drying 
qualities. It is also excellently suited for covering the strong smell 
of mineral oil, and on account of its very low price is useful for 
perfuming any preparations which have an unpleasant smell. 
Oil of Borneo Camphor or Borneene is a liquid hydrocarbon 
isomeric with oil of turpentine, secreted by the Dryobanalops Cam- 
phora; it is obtained by tapping or felling the trees. It is recorded 
that from a tree felled in the Island of Lebua about 5 gallons of 
oil were removed from a cavity scooped in the trunk *, ‘This oil 
holds in solution a resin and a solid camphor, Borneol. By frac- 
tional distillation the oil can be separated into two portions, one 
lighter than the other, but both of like composition. 
Borneene can be obtained by distilling the wood of Dryobanalops 
Camphora with water. The distillate can be fractionated into two 
oils, one boiling between 180° and 190° C., the other at 260°. A 
resin can also be separated which melts at a temperature a little 
above 100° C. 
Borneene is formed when Borneol is gently heated with phos- 
phorie anhydride. It can also be obtained from essential oil of 
valerian by submitting that oil to fractional distillation and heating 
the first portions of the distillate with potassium hydrate, which 
takes up valerol while Borneene passes as a distillate. 
Planks are sawn from the finest parts of the wood and used for 
making chests, which are useful by reason of their strong odour 
for preserving furs and clothes from moth.
