The cineol was determined by the resorcinol method in 

 the portion distilling below 200°, and the result gave 12'5 

 per cent, of that constituent for the crude oil. 



The oil is thus shown to consist largely of terpenes,. 

 so that redistillation of the two first fractions was under- 

 taken. Three per cent, of the first fraction was removed, 

 which boiled below 162°. The second fraction was then- 

 added and the whole fractionated, in order to further separate 

 the lower-boiling terpenes. Between 162-172°, 34 per cent, 

 distilled ( = second fraction); between 172-175°, 16 per cent. 

 distilled. These fractions gave the following results: —

These results suggest that as phellandrene is absent the 

 principal terpene in the oil of this species is laevorotatory- 

 limonene, and that pinene is only present in small quantity. 

 For industrial purposes the essential oil of this Eucalypt has 

 little commercial value at present. 



4. Eucalyptus Bosistoana, F. v. M. 

 (Australasian Journal of Pharmacy, October, 1895.) 



"Red Box." 



This species probably occurs in South Australia, as 

 material received by us from Mount Templeton (C. N. Gren- 

 f ell) and Seven Hills (Clara A. Chesterman) resembles this 

 Eucalyptus more than any other. The material, however , 

 was hardly perfect enough to speak definitely. 



Its botanical and chemical characters are given in our 

 work, "Eucalypts and Essential Oils," p. 61.
