of the first consignment; these leaves were obtained so that the 

 constancy of the species might be tested. The oil is the same, 

 only a little richer in eucalyptol; it varies only in the percentage 

 amount of its constituents and in its physical properties in the 

 ratio usually experienced in Eucalyptus oils of the same species; 

 this slight alteration may be governed, perhaps, by situation and 

 soil. 



Average yield of oil from three distillations = 1-613 per cent. 



Specific gravity crude oil at 13° C. =0916. 



Specific rotation crude oil = [a]D + 1*1°. 



Eucalyptol, crude oil = 65 per cent. 



This species of Eucalyptus may thus be considered to be an 

 excellent one for distillation, as the yield of oil is large. The oil 

 is excellent; there is a comparative absence of high boiling con- 

 stituents, consequently on rectification little would be lost. The 

 species is obtainable in any quantity. We have pleasure in 

 bringing this species under the notice of those interested in the 

 distillation of Eucalyptus oil. The results obtained are those 

 that would maintain commercially the leaves and terminal 

 branches being collected and used in the same way (Henry G. 

 Smith). 



It gives a plentiful supply of leaves, ospecially as the clusters 

 would not be destroyed and would always grow up again (W. 

 Bauerlen). 



Kino — The kino is not plentiful. It is friable, dissolves in 

 boiling water, but becomes turbid on cooling, the turbidity being 

 caused principally by eudesmin, but aromadendrin is also present 

 in small quantity ; a very dilute aqueous solution gives with 

 ferric chloride a green colouration (Henry G. Smith). 



Mr. W. Bauerlen, who was the first to collect this Eucalypt, 

 states : — "This species, also a Mallee, grows in the same way as, and 

 associated with Green Mallee, E. viridis, R.T.B.; but the leaves 

 are so different in colour, &c, as to distinguish it at once. The 

 bark is much the same, but persistent often right out to the branches;
