264 AUSTRALIAN NATIVE PLANTS. 
abundant, much cheaper, and containing the usual remedial 
properties assigned to Eucalyptus oil. It is very fluid, almost 
devoid of colour, has a persistent and camphoraceous odour, is 
slightly soluble in water, but completely so in alcohol, oils, fats, 
and paraffin. It is not caustic, like carbolic acid, nor does it pro- 
duce much irritation of the skin, unless applied with extreme 
friction; in that case the application of an emollient will speedily 
give relief. It is very destructive to low organic growth. Itisa 
powerful antiseptic, and by some practitioners stated to be more 
than three times as strong as carbolic acid in preventing the 
development of bacteria. Its uses are manifold. 
Messrs. Schimmel & Co., Dresden, state that this oil differs 
from all other Eucalyptus oils known to them, and contains, 
probably, scarcely any oxygenated constituents; it more likely 
consists of at least one well-characterized terpene (Cy Hy.), and 
possibly a small quantity of cymol. Its specific gravity is 0.890 ; 
it boils practically between 170° and 180°, and is levogyre. Obser- 
vations on three different samples, gave, in a 100 mm. column, 
a rotatory power of 27°, 28.4°, and 28.6°; consequently, this 
property allows of it being easily distinguished from the dextrogyre 
oil of Z. globulus. (Pharm. Fourn., April, 1888.) Messrs. 
Schimmel also allege, that in consequence of this oil having been 
proved to contain no Eucalyptol, the demand for it has fallen off. 
The following essential oil is described as from £. jisszlis, a 
variety of Z. amygdalina: Pale, reddish-yellow oil, of 0.903 sp. 
gr.; boils at 177° to 196°. (Wittstein and Mueller.) 
Speaking of Eucalyptus oils, Mr. Bosisto says: (Pharm. 
Fourn.) “ People in England would always speak principally of 
E. globulus, but the fact is that it is considered in Australia to be 
the worst of the whole lot.”” Now the incorrect labelling of ship- 
ments from Australia has much to do with this practice, but it is 
hoped that scientific people throughout the world will use the 
correct species-name when they are able to do so. 
Mr. Leopold Field, the soap-maker (at a meeting of the 
Pharm. Soc., at the close of the Colonial and Indian Exhibition), 
said the oil they always obtained came to them in iron tins holding 
about 56lbs., and it was labelled Z. globulus, and sometimes, by
