the Montserrat Co., Ltd., which comes slightly lower in price. 
The quality is exceptionally good. 
Lin aloe Oil. Owing to difficult weather-conditions, our purveyors 
in Mexico have only been able to carry out the terms of their con- 
tracts with, considerable delays, which have led to scarcity in the 
local stocks. In other respects, consignments at the various ports 
which have direct communication with Mexico were also scarce and 
insufficient, and the prices consequently moved upwards almost con- 
tinuously. 
As long as these conditions continue, a change in the situation 
must not be thought of. 
Oil of Sweet Marjoram. Genvresse and Chablay have iso- 
lated, from two oils of sw^eet marjoram of different origin, a Isevogyre 
pinene, a new ketone C^q H^^g O, and a body which is probably identic 
with pulegone. Pinene was identified by its hydrochloride and the 
nitrosochloride. The ketone boiled at 208 to 209°, at 740 mm, and 
yielded compounds with sodium bisulphite, hy droxylamine , and semi- 
carbazide. The body, supposed to be pulegone, boiled at 220 to 
225^, at 738 mm, and yield an oxime melting at 118 to 119°. 
Oil of Milfoil. A. B. Aubert^) gives in a preliminary communi- 
cation some details on milfoil oil. Specific gravity 0,9217 (at 22°); 
nj)2o° 86 parts by volume of the oil passed over at 170 to 235°, 
at reduced pressure; the distillate showed, according to the fractions, a 
more or less deep blue colour. The first portions of the oil, boiling up 
to 190^, may possibly contain chiefly cineol^) and further some small 
quantity of an aldehyde. Compounds of sulphur were not detected. 
The principal fraction of the boiling point 210 to 220°, representing 
50 parts by volume, when freshly distilled, had a blue colour, which 
changed into yellowish-green after 1Y2 year's standing in the dark. 
Analysis and determination of molecular weight led to the formula 
C^qH2o- This fraction had the following constants: Rotatory power 
(in an 100 mm tube) — 14,2'^; index of refraction 1,492; boiling 
point 254° at 754,8 mm. The action of bromine and of hydrochloric 
acid yielded no characteristic products. On the other hand, the oil 
gave most of the reactions with terpenes. The blue distillate of mil- 
foil oil differs, in the opinion of the author, from that of oil of 
chamomile.
