In the portions not reacting with phthalic acid anhydride, a com- 
pound was present which had a characteristic menthone odour. This 
fraction distilled from 200° to 205°. di50 = 0,9372; = — 3^50'. 
On treatment with semicarbazide in alcoholic solution, a solid semi- 
carbazone was obtained, which, after repeated recrystallisation from 
alcohol, melted at 177° to 178°, and which, on being heated with 
dilute sulphuric acid, split off an oil with a strong menthone odour. 
Whether it was here a question of menthone, or of an allied ketone, 
could not be decided, as the quantity of pure substance obtained was 
insufficient for an analysis. From a fraction boiling from 90° to 105°, 
at 6 mm, a semicarbazide compound could be obtained, which, after 
recrystallisation from alcohol, melted indistinctly at 200^, and which 
on distillation with dilute sulphuric acid split off an oil with an odour 
of cuminic aldehyde and anisic aldehyde. On oxidation of this oil 
with dilute solution of potassium permanganate, only anisic acid of the 
melting point 180° was obtained. 
It follows that the presence of anisic aldehyde in the essential 
oil of Acacia Farnesiana has now been proved, whilst the exact deter- 
mination of cuminic aldehyde has not yet been possible, owing 
to the apparently exceedingly minute quantity in which it is present 
as a constituent of this oil. 
The examination of the oil of acacia blossoms is being continued. 
Cedar Oil, inspissated for optical purposes. With regard 
to this preparation, we would point out that, contrary to all other 
essential oils, this oil should not be kept in too cool a place, as otherwise 
it frequently becomes turbid. The turbidity may, however, generally 
be easily removed by warming the oil. 
Cinnamon Oil, Ceylon. The prices of the fine brands of 
cinnamon chips fluctuated during the last half-year between 2 d. and 
2^4^ d., and those of cinnamon oil in the same proportion. 
The export of cinnamon chips from Ceylon was : — 
in 1903 .... 2253269 lbs. 
against „ 1902 .... 1763679 „ 
„ 1901 .... 1 516083 „ 
„ 1900 .... 1863406 „ 
In this export, Germany participated in the first place with 687159 lbs.,
