is only during the last twenty-five years that many of the taxonomic problems left 
unsolved since Mueller's death have been earnestly worked at, and, in a similar 
complementary way, we have had the valuable chemical work of H. G. Smith extending 
the knowledge laid down by previous chemists. 
In the following list of papers, &c., arranged chronologically, it is of course 
possible, in a number of cases, to point out those which refer to E. globulus, but in some 
others this cannot certainly be said, and, in many papers, more than on,e species, are 
referred to. 
\Z\. Bosisto, J. Exhibited the oils of twelve species oi Eucalyptus in the 
Victorian Exhibition of 1861 (a sort of dress rehearsal of the Victorian Court oi the 
London Exhibition of 1862). This was a, I may say the, pioneer Eucalyptus oil exhibit. 
1862. Osbome, J. W. " On the Essential Oils and Resins from the Indigenous 
Vegetation of Victoria," by J. W. Osborne, Rep. Brit. Assoo. Adv. Science for 1862, p. 48. 
The writer of the note was a juror at the London Exhibition of 1862, and the oils were 
stated to have been distilled under the auspices of Mueller. The species of Eucalyptus 
oils purported to be amygdalina, oleosa, sideroxylon, goniocalyx, globulus, corymbosa 
(sic), fabrorum (obliqua),fissilis (regnans), odorata, Woollsii (longifolia), rostrata, viminalis. 
Following are compilations in regard to the oils produced by Mr. Bosisto at the 
1862 Exhibition: 
Simmonds, P. L. " Essential oils from, the genera Eucalyptus and Melaleuca, 
suitable for general application in the Arts." The Technologist, iii, 11. An abstract 
of the catalogue of Victorian products at the London Exhibition of 1862. 
Jackson, J. R. " On the products of the genus Eucalyptus." Intellectual 
Observer, ix, 241 (May, 1866). Notes on miscellaneous products, oUs, mannas, timbers, 
&c. Allusion is chiefly made to E. oleosa, E. globulus, E. viminalis, E. tetraptera. 
E. gigantea. The paper has drawings of a flowering twig of E. tetraptera, and a magnified 
section of its leaf, which have no bearing on the economic questions. 
1865. Bosisto, J. " Abstract of a paper on the yield and uses of Volatile Oils 
from native and imported plants in the Colony of Victoria." Trans. R. S. Viet., vol. vi, 
p- 52 (1865). 
f^is(E.g.hbidus) oil ranks foremost ia value among those obtained from the Eucalypti, on account 
of its solveut powers, its illuminating properties, and its power of fixing the aroma of allied oils. (Bosisto, 
p. 55). 
The solvent power of these oils is. a,ko great, varying 8oro,ewha,t in the different types; that of the 
globulus or Blue Gum type being superior to that of all other oils hitherto discovered. (Offic. Rep. Intercol. 
Exh. Melb., 1866-7, p. 319). 
It will be observed that in these passages, referring to the recrudescence of the 
interest in Eucalyptus oils developed by Mr. Bosisto in the early sixties, emphasis was 
drawn to their value as solvents, rather than to their medicinal properties. We have 
here the first prominent modern scientific declaration as to the importance of the oil 
of E. globulus.
