Group II. — In this Group are placed the following Eucalypts yielding an oil 

 consisting principally of pinene and cineol ; the latter constituent hot exceeding 40 

 per cent., determined by the phosphoric acid method at time of distillation. Phel- 

 landrene and aromadendral* are absent.

[Nos. 24, 25, 26, 29, 30, 31, 32, 33, 34, 35 and 43 are not in this Group in 1st 

 Edition]. 



[This is an artificial chemical group, inasmuch as its oils are mainly mixtures of 

 pinene and cineol, the quantity of the latter constituent present being fixed at the 

 arbitrary percentage of forty. Accordingly it is not a matter of surprise that, 

 botanicaliy, it consists of heterogeneous species. For example, we have included in 

 this group — Stringybarks, Tallow-wood, Boxes, a Mahogany, Sugar Gum and other 

 White Gums, Yates, and Ironbark and Ribbony Gum.] 



Group III. — Class (a). In this Group are placed the following Eucalypts 

 yielding an oil consisting principally of cineol and pinene, in which the cineol exceeds 

 40 per cent., at the time of distillation, but under 55 per cent. Phellandrene is absent 

 and aromadendral very rarely occurs.

* The name Aromadendral is used throughout this work in a general sense to denote the presence of one or more 

 members of this group of characteristic aldehvdes; which includes ouminaldehyde and cryptal. See the article in this 

 work on these aldehydes (R.T.B. and H.G.S.),
