Angophora Oils. Oil of Angophora Bakeri. Leaves collected in the neighbour- Sm 
hood of Paramatta, Australia, from this myrtacea yielded, according to Baker and “a 
Smith*) 0.31 per cent. volatile oil; d 0.8719, a) + 35.6°, n, 1.4660. The following bodies 
proved to be present: — «-pinene, geraniol, geranyl acetate and valerate, a sesquiterpene, 
amyl acetate, and a volatile aldehyde, The content of «-pinene amounted to 80 per cent. — he 
Oil of Angophora melanoxylon, R. T. Baker. The leaves of this species yielded a 
0.19 per cent. oil with the constants: — d 0.8809, «+ 24.99, np 1.4678. Its composition “ig 
was similar to that of the above-mentioned oil. | | ee 
Oil of an Angophora species (2). The oil of a still unnamed species sao contained 
pinene, geranyl acetate, and valerate; d 0.8703, «, + 36.39, np 1.4669. ; 
Unfortunately, the abstract does not mention where the original paper was published |

Anise Oil. Small quantities of anise are ps in Cyprus?), the exports amounting ~ 
in the last years to 1000 to 2000 cwt. annually., In 1915, 1112 cwt., valuing 1823 £ 
were shipped to Egypt. A sample was investigated at the Imperial Institute, London, _ 
and yielded on steam-distillation 2.8 per cent. of a faint yellow oil: — dis0 0.990, ap EO, i.

Oil of Artemlets annua. In page 4 of our last Report we mentioned, following — 
a description of this oil by Y. Imada*), as constituents cineole and another substance 
CioHigO. As we cull from another abstract of the same paper, the presence of cineole : 
was established by oxidation into cineolic acid and by preparing the iodole addition om 
compound. The oil, a light yellow liquid of camphoraceous smell, had the constants: 4 
acid v. 2.1, sap. v. 36.4, sap. v. after acet. 66.36, methoxyl v. 0. ae 
The second body CioHi.O has been investigated by Asahina and Yoshitomi*) and ‘a 
termed “artemisia ketone”. They heated the semicarbazone (m. p. 95 to 96°) with a 
concentrated hydrochloric acid under a reflux condenser for six hours; the regenerated — 
ketone was inactive and showed b. p. 182°, dvs 0.8906, npiso 1.4695. It contained two ~ 
double linkings and yielded in consequence, when reduced according to Fokin-Will- ~~ 
statter, a tetrahydro derivative CioHsO, tetrahydro artemisia ketone, b. p. 1739; ~ 
d= 0.8262; np 1.42425; m. p. of the semicarbazone 134 to 135°. It seemed £0; be of »—
