own researches speciall}' into consideration, is a matter for which one 
can hardly find fauh with them, but for this very reason it may be 
assumed, that the views thus set forth by them will not always meet 
with unanimous approval on the part of their more immediate col- 
leagues. The discussion of the individual eucalyptus - species is con- 
ducted from the chemical point of view, i. e. according to the principal 
constituents present in the individual oils. This is followed by a repro- 
duction of various wmks by H. G. Smith from the 'Proceedings of 
the Royal Society of N. S. Wales' respecting the composition and 
constituents of a few eucalyptus oils, and finally details are given on 
the method of distilling eucalyptus oils, as in vogue in Australia, which 
method is elucidated by well-executed pictures. The work ends with 
a clearly arranged table which permits ready reference to the properties 
and constituents of any eucalyptus oil. 
This publication meets a real want, and is all the more to be 
welcomed, as wdth the large number of eucalyptus species described 
and the still larger number of synonyms, it was not at all, or hardly, 
possible for anyone who had not made a special study of this subject, 
to find the w^ay in such a chaos. 
Fennel Oil. We are in the pleasant position of now being able 
to supply our own distillate from purified Galician seed of which we 
have since January received every month a number of truck-loads. 
Gardenia Oil. E. Parone^) has published a work on the prop- 
erties and chemical composition of the essential oil of gardenia, from 
which we abstract the following: 
The gardenia oil obtained by maceration from the fresh gardenias 
gathered during the flowering season, has a yellowish colour, and 
possesses at 20,5° the specific gravity 1,009. The specific rotation 
is [a] f) = -|- 1,47 ^, at 20°, in a 50 mm tube. At ordinary pressure 
the oil commenced to boil at 204° with partial decomposition; at 
a pressure of from 12 to 15 mm the bulk passed over between 84° 
and 150°. Par one has detected the following bodies as constituents 
of gardenia oil : benzyl acetate, styrolyl acetate, [acetate of the methyl 
phenyl carbinol QH5 • CH • (OCOCH3) CH3] , linalol, linalyl acetate, 
terpineol, and methyl ester of anthranilic acid. 
Benzyl acetate represents the principal constituent of gardenia oil, 
whilst the aroma peculiar to the oil is chiefly due to the styrolyl acetate. 
Geranium Oil. Within the last 6 months the prices of the 
Algerian oil have declined to a not inconsiderable extent, and they 
may possibly drop still lower, as, according to our personal experience, 
the cultivation is now carried on on a much larger scale. A suspicious
