Eucalyptus Oil. —There was no shortage of good globulus oil since | "ie ae . 
_ of the war; Spain especially delivered considerable quantities, which for very good 
reasons found its way chiefly to Germany. As we hear, the production in Spain has 
considerably increased, and can take up the competition with the Australian: oil” 
especially as regards quality. Amygdalina oil was only offered in very small quantities, 3 
and appears to fall short of the demand by far, as in prewat days, when it was sought ; 
for vairous technical purposes. eee te 
At present there are about 200 eucalyptus oil factories in Atsiane Sifty of which. i 
are on Kangaroo Island, six in Adelaide, four in Tasmania and one in Queensland. — 
Besides the oils used in medicine and in the smelting and metallurgical industries — i 
Eucalyptus Globulus, Lab. and Eucalyptus amygdalina, Labill. and the corresponding 
varieties — oils of lesser used sorts are now prepared as that of Eucalyptus Macarthuri, 4 
Deane and Maiden and E. citriodora, Hook. for the production of geraniol, citronellol o 
(citronellal?), geranyl acetate &c.’). a 
In Victoria 1917 to 1918 806977 lbs. of eucalyptus oil were distilled which deheasyl : 
the yield of the previous year by 161 tons. The “Blue mallee’ (Eucalyptus polybractea, 
R. T. Baker) which grows in the territories of the north-west is now systematically | 
cultivated. In the Wombat Forest, where many small distillation establishments are at : 
work, only the “peppermint tree” (EZ. piperita, Sm.) is used. Several larger works are in 
Bendigo (Sandhurst), which use the leaves of “Red” and “White Ironbark” (E. sidero-> 4 
phloia, Benth. and E. paniculata, Sm.). These shrub- like plants are still to be found 4 
in great quantities in the neighbourhood’). Meee. 
The phosphoric acid method for the estimation of cineole, which from our ex. b 
perience and that of others most be classed as untrustworthy‘), has again been 
thoroughly tested by C. T. Bennett and M. S. Salomon®). They come to the result, — 
that the most accurate results are obtained with a eucalyptole content of under 85. per cent. a 
if one proceeds exactly according to the British pharmacopceia and uses 5 Cc: of 
phosphoric acid. Both the phosphoric acid and the arsenic acid process give low 
results with a high eucalyptole content. The method however suffices for the purposes 
of the pharmacopeeia. These explanations do not alter the unfavourable epee wi Be 
have formed of the phosphoric acid process. \ seid le (a ar 
Eucalyptus oil produces apparent symptoms of poisoning if taken in large qu |

unconscious for half an hour after taking 20 cc. of cuca rer oil; but he was
