further course of his examination i), E. Deussen attempted to produce 
the dextrogyre cadinene in the pure state from West Indian sandalwood 
011 by repeated fractional distillation over sodium. The hydrocarbon thus 
obtained had the composition H24, and showed the following constants: 
boiling point 260° to 261^, at atmospheric pressure; di50 = 0,9247; 
= 50°; Up = 1,5 108. With hydrochloric acid it formed a hydro- 
chloride melting at 118°. 
He further obtained a hydrocarbon of the formula Q5H24 which 
had a lower dextrorotatory power; it showed a great tendency to- 
become resinified, and yielded no solid hydrochloride. This hydrocarbon 
agrees in its properties with galipene. 
The laevogyre cadinene hydrochloride obtained from West Indian 
sandahvood oil yielded, by splitting off the hydrochloric acid, laevogyre 
cadinene of the boiling point 264° to 266° (only the bulb of the 
thermometer in the steam); aj) = — 89° to 108°. 
Spearmint Oil. The prices of this American speciality have 
gradually advanced more than 100 per cent, in sympathy with those 
of peppermint oil, and it is feared that the quantities produced, jointly 
with some stocks left over from the previous season, will not be suf- 
ficient to meet a normal demand. In the further course of business 
the quotations may possibly go still higher. 
Star-anise Oil. Since our last Report, the prices of this im- 
portant article have been materially unchanged. The oil of Chinese 
origin reached its lowest level at 4/2 per lb.; that from Tonquin at 
12 francs per kilo, — but even those figures were not able to create 
considerable demand for it, a fact which clearly shows to what extent 
the trade has lost interest in an article which, at one time, w^as one 
of the pet objects of speculators. 
We prefer, now as formerly, the Tonquin oil, on account of its 
higher anethol-content; the trade, however, following ancient habits, 
contmues to admire the Chinese product, and frequently gives pre- 
ference to brands which have been proved to have been positively 
adulterated. 
A detailed examination of star-anise oil has recently been published 
by Tardy 2). His material was an oil from which the greater part 
of the anethol had been removed, and which showed a Isevogyration 
of 3° 15^ In addition to the already known bodies^) pinene, phel-
