The Eucalyptus oils have been classified by Baker and Smith* 

 according to the relative amounts of cineol (eucalyptol), pinene, 

 phellandrene, piperitone, or aromadendral which are contained 

 in the crude oils. The groups or subgroups, containing the oils 

 that were examined, are as follows: — 



Group iii«x. — The oils consist principally of cineol, which is 

 over -10%, and of pinene. Phellandrene is absent. A', globulus 

 belongs to this subgroup. 



Group iii&. — Similar to the last, but aromadendral replaces 

 some of the pinene. 



Group iiic. — Similar to iiia., but phellandrene replaces some of 

 the pinene.
