accompanying odour reminds one of dill and caraway (Proc. Roy. Soc. Viet., 1893, p. 195). 
" A firm in Adelaide, which had introduced the oil into the market, at first designated 
it as coming from Eucalyptus oleosa. This is due to the fact that E. cneorifolia is now 
considered as a separate species, whereas it was formerly considered as a variety of 
E. oleosa." (Benefit von S. & Co., April, 1892, p. 44. See also April, 1891, p. 33.) 
An early report says : 
" Messrs. Helbing and Passmore have just concluded an investigation on the 
properties and constituents of certain Eucalyptus] oils, including Cuming's brand 
(the produce of the narrow-leaf Eucalyptus, E. cneorifolia), and publish their results 
in the form of a " Pharmacological Record." In brief, these indicate that Cuming's 
oils are free from aldehydes, and contain : second quality, 44 per cent., first quality 
50 per cent., and the re-distilled oil, 58 per cent., of eucalyptol thus corroborating 
the high opinion already formed of this oil. The report contains many interesting 
figures regarding these and other oils examined, which will repay attention. The 
authors conclude with a proposal to alter the Pharmacopoeia " characters and tests " 
in such a way that only Eucalyptus oils above sp. gr. 0910 would be recognised. We 
do not think their evidence sufficiently justifies this recommendation, which would 
virtually exclude the amygdalina oil, and chemical experiments alone do not enr-.ble 
investigators to decide that a Eucalyptus oil is of " no medicinal value." (Chem. and 
Drugg., llth June, 1892, p. 837). See also 13th May, 1893.

The German " Bericht " of April, 1888, p. 18, contains the following statements : 
' The hydrocarbon accompanying the Cineol, and formerly called Eucalyptene, is 
d-Pinene. It is probable that Eucalyptus oil contains other terpenes besides Pinene. 
. . . ' The unpleasant, penetrating, and irritating odour of crude Eucalyptus oil 
is occasioned by different aldehydes, principally valeric aldehyde, besides butyric and 
capronic aldehydes." 
The Report of October, 1892, p. 23, speaking of E. globulus, says: "Now 
included in Pharmacopoeia Japonica. Requirements': ' Essential oil of the leaves of 
Eucalyptus globulus distilled with addition of water, limpid, colourless or light yellow, 
reacts neutral, is of peculiar odour, gives no detonation with iodine. Mixes in equal 
parts of alcohol. Sp. gr. -900 to -925.' ' 
Schimmel's guarantee of their oil 60 per cent., Eucalyptol and absence of 
Phellandrene. The latter constituent, by way of a warning, to be stated to be in 
Australian oil. . . At p. 23 they say, after an examination of six oils, " Considering 
these facts and also taking into account (what is probably no longer contradicted), 
that Eucalyptol is the therapeutically active and therefore the most important
