conclusion lie points out that an admixture of from 5 to 10 per cent 
of castor oil, in eucalyptus oil of good quality, may easily be over- 
looked unless special tests are applied. — Chem. & Drug., 1905, v. 66, 
pp. 33-34. 
Umney and Bennett report a study of the essential oil of Eucalyp- 
tus polybractea which, judged by the cineol content (79 to 80 per 
cent) appears to be of the highest medicinal value — not even second 
to the oil of Eucalyptus globulus. — Year Book of Pharmacy, 1905, 
p. 80 (from Pharm. J., Bond., v. 20, p. 143). 
An abstract (from Bull, of the Imp. Inst., 1905, v. 3, pp. 4-6) 
enumerates a number of eucalyptus oils from New South Wales which 
were found to contain the “ peppermint ketone.” — J. Soc. Chem. Ind., 
Lond., v. 24, p. 749. 
Baker and Smith discuss some West Australian eucalypts and 
their essential oils. They include brief botanical descriptions and 
some account of the results of chemical analyses of E. calophylla , 
E. diversicolor, E. salmonophloia , E. redunca , E. occidentalis , E. 
salubris , E. marginata , and E. gomphocephala. — Pharm. J., Bond., 
1905, v. 21, pp. 356, 382. 
Schimmel & Co. assert that at the present time Australia controls 
the market in the oils rich in eucalyptol, no other source of supply 
being able to compete against such enormous production. They also 
direct attention to the work that is being done by J. BI. Maiden in 
connection with his compilation, “A critical revision of the genus 
Eucalyptus,” and outline the contents of the sixth number of this 
comprehensive work. — Semi-Ann. Rep., Schimmel & Co., 1905, Oct.- 
Nov., p. 33. 
Taylor, H. S. (Bancet, Bond., 1905, II, p. 963), reports a case of 
acute poisoning by eucalyptus oil. — Reference from Ind. Med., 1905, 
p. 1137. 
OLEUM FCEmCULI. 
Schimmel & Co. discuss some of the economic questions bearing 
on the production and the price of oil of fennel. — Semi- Ann. Rep., 
1905, Apr -May, p. 39. 
Umney and Bennett point out that there is usually some difficulty 
in starting crystallization unless a crystal of anethol is available. 
They also assert that they have not met with any oil of fennel sophis- 
ticated with volatile oils containing phenols, for which a test is in- 
cluded in the U. S. P., VIII. — Pharm. J., Bond., 1905, v. 21, p. ,146. 
Semmler, F. W., discusses the structural formula for fenchone and 
some of the possible derivatives. — Chem. Ztg. Cothen, 1905, v. 29, p. 
1313. 
OLEUM G AULTHEKXffi. 
Umney and Bennett point out that reference to the occasional red- 
dish tint of oil of wintergreen is omitted. In several samples re-
