Jowett, H. A. D. "The Botany and Chemistry of Essential Oils." Pharm. 
Journ., (3), xxiv, 6 (1st July, 1893). Deals with the botany very briefly as regards 
Eucalyptus, and the chemistry a little more fully, although it is not a lengthy paper. 
There are notes on Phellandrene, Cineol, Citral, Geraniol and its acetate.

Dott, D. B. " The Tests for Eucalyptus Oil." Pharm. Journ., (3), xxiv, 510 
(23rd December, 1893). He criticises the various tests for the oil as laid down in the 
old B.P., and he refers in terms of praise to the researches of R. H. Davies and Pearmain, 
and Helbing and Passmore. In the discussion Mr. Coull recommended increased use 
to be made of the botanical designation of an oil. Mr. Coull was simply ahead of his 
time, and Australian botanists have long pleaded in this direction, but the time is 
not yet.

has a useful bibliography, and it is the first scientific investigation of Eucalyptus oils 
in Australia.

Holmes, E. M. " Eucalyptus Oil " Pharm. Journ., (3), xxv, 501 (12th 
December, 1894). He points out that the reputation of this oil as a therapeutic agent 
rests upon an unsatisfactory basis. On the one hand, Eucalyptol is claimed to be 
the active ingredient, whilst on the other, Phellandrene is the constituent in the oil 
on which its reputation is partly based. Nor is it known at present how far the 
antiseptic action is due to Ozone, to Eucalyptol, to Phellandrene, or to some of the 
aldehydes present in the oil. He quotes Mr. E. E. M. Payne for a description of the 
method employed in distilling Eucalyptus oil at that time.
