quantities of water from the surrounding soil, and of thus dessi- 
cating the germs of malaria. Baron Mueller’s services in forwarding 
seeds of Lucalytus globulus and other species to the Trappist 
Fathers of Tre-Fontane (through the late Archbishop Gould, of 
Melbourne), must not be forgotten. 
“ We have as yet no accurate pathologic data on the effect 
of the exhalation of Eucalyptus forests on phthisic patients; but 
I anticipate, that in the same manner as the air of dense pine- 
woods is apt to stay the inflammatory processes in diseases of the 
respiratory organs, so the vapours of our Eucalyptus forests, the 
odour of which we so easily perceive and recognize, will likewise 
arrest the progress of these sad diseases, more particularly in their 
earlier stages, and probably more so than sea-air, notwithstanding 
its pureness, the atoms of bromine and iodine carried with it, and 
the increased ozone which it evolves. Indeed, I should assume 
that sanitarian dwellings could nowhere on the whole earth be 
provided for phthisic patients more auspiciously and more hope- 
fully than in mountains clothed with Eucalyptus forests in extra 
tropical Australia, and at elevations (varying according to latitude 
from 1000 to 3000 feet), where the slightly rarified air of a very 
moderate humidity pervaded by Eucalyptus vapour, together with 
the comparative equability of the temperature, would ease the 
respiration greatly. This assumption is largely based on the 
facts that no other gregarious trees in the world evolve essential 
oil so largely as our Eucalypts, unless, perhaps, some of the most 
terebinthine pines of colder climes, and that thus is most copiously 
afforded an oily volatile emanation, befitted to absorb and con- 
dense oxygen into ozone, the most powerful vitalizing, oxidizing, 
and, therefore, also, chemically and therapeutically disinfecting 
element in nature’s whole range over the globe.” (Baron von 
Mueller in Lucalyptographia.) 
It is but right to quote testimony on the other side of the 
question. Speaking of Z. crebra, the Rev. J. E. Tenison-Woods 
states (Proc. Linn. Soc., N.S.W., 1882, 336): “On the Peak 
Downs, about Clermont and Copperfield, it is especially plentiful, 
and all around the Hodgkinson diggings. I mention this fact just 
to show that whatever febrifuge qualities the Eucalypts may possess,
