“Called “ Mountain Ash,” “ Spotted Gum,” etc. (For other vernacular 
names, with the localities in which they are used, see ‘‘ Timbers.”’) 
The essential oil of this Eucalypt is pale yellow; of pungent, 
penetrating, rather disagreeable odour, and exceedingly unpleasant 
taste. Sp. gr.,o.918; boiling point, 152° to 175°. (Wittstein 
and Mueller.) r1oolbs. of fresh leaves gave 160zs. of essential 
oil. (Bosisto.)

A “ Mallee,” or ‘‘ Desert Gum.’’ 
Baron Mueller found that rooolbs. of fresh twigs of this 
plant (comprising perhaps 50olbs. of leaves) yielded 5430zs. of 
essential oil. 
Forms, with other species of Eucalyptus, the ‘“ Mallee”’ 
country of Victoria, New South Wales, Queensland and South- 
western Australia.

The essential oil from the fresh leaves gives a yield of 1.875 
per cent; in other words, 6720zs. of oil from one ton of leaves; 
it has a slightly acid reaction, and a specific gravity of .880. 
(Staiger.) Dr. Bancroft observes that this oil is among the more 
agreeable oils derived from the genus, and describes the odour as 
being intermediate between oil of geranium and oil of peppermint. 
It has been suggested as a soap-perfume. 
Messrs. Schimmel & Co. have recently published the follow- 
ing report on a Queensland sample of this oil: ‘ Specific gravity 
0.890; boils from 170° to 250°. This oil differs from all other 
described Eucalyptus oils, and has an odour resembling that of 
cumin oil. It contains terpene and cymol, and among the
