being 2.5 per cent. in ee and 3.4 per cent. in October. The oil distiliag in the f ¢ 
hour is very rich in cineole and free from aldehyde-like bodies, and is set aside f 
pharmaceutical use. The product of the second hour is reserved for mineral separations a 
and other technical purposes. The crude oil had the following characters: — diso 0. lease 
. + 2.89, nps00 1.4644, soluble in 1.2 vol. 70 percent. alcohol, and contained 70 per cent. 
cineole. The “first hour” oil had a cineole content of 69.5 to 84 per cent., the Heuconea 
hour” oil of 20 per cent., the characters of this oil being: — diso 0.9291, a-+-2.20, a 
Np 1.4720. soluble in 1.1 vol. 70 per cent. alcohol. The “third hour” oil had similar 
properties and contained 26 per cent. cineole. ae 
Oil of Eucalyptus Globulus. In a former Report?), we have drawn attention to the 
fact that the well-known Eucal yptus Globulus tree is unsuited for tropical climate. We 4 
find. the same statement in an article on eucalypts in the Federated Malay States*), 
the climate of which: does doubtlessly not agree with that eucalyptus species. The," 5 
best success has been obtained there with E. rostrata (Red Gum) and E. citriedora (Lemon- 
scented Gum). Seedlings raised from eucalyptus thought to be LH. citriodora have. a 
‘thrived particularly well and looked very healthy; its correct botanical identification is, 
however, only possible if they should flower. Probably, the humid atmosphere of the 
Federal Malay States is unsuited for most eucalypts. 
Oil of Eucalyptus platypus. The latter species is. amongst the comparatively few 
eucalypts about whose oil only little was hitherto known. Recently, J. C. Earl*) obtained 
from’ the fresh leaves of this species about 1 per cent. of oil with following characters++—" 
d 0.9045, @p + 9.1°, np20o 1.4675, sap. v. 6, ester v. after acet. 24. It contained 59 percent. 
cineole (by resorcinol absorption method), but neither aldehydes nor ketones. It gave te 
20 to 25 percent. of pinene, 10 to 15 percent. of phellandrene, 10 to 15 percent. of ‘ 
aromadendrene and 5 per cent. of alcohols free and combined. cet A 
Nothing is to found in the abstract as to the method of identifying these constituents. ~ 
Oil of Eugenia Smithii. A. E. Dawkins®) obtained from the leaves of Hugenia” 
Smithii (N. O. Myrtacee), in May, 0.44 percent. of pale yellow, oil with a sweet pene-— 
trating odour; dis0 0.866, ¢p + 35°, np200 1.4701. Another distillation in July gave a yield ee: 
of 0.28 percent. This oil had d0.863, «)-+34.0°, np)1.4675, and contained 80 to 
90 per cent. of d-a-pinene, 4 percent. of esters, and 3.7 percent. of alcohols: 
Geranium Oil. While engaged on experiments on utilizing the decane in the — 
Nilgiris, Puran Singh®) was struck by the profusion of wild geranium plants there, «— 
amongst them especially Pelargonium graveolens, L’Hérit. (P. terebinthaceum, Harv. et i 
Sond.)*). One‘ experimental distillation of the entire plant of geranium, whose leaves ~ pe 
had began to turn yellow and flowers opened, gave 0.044 per cent, oil. Considering 
the season and the state of the plant collected, the yield was satisfactory, ‘and oe mi
