removed, was fractionated in vacuo. The terpene fraction had the specific 
gravity 0,842 at 20°, and consisted chiefly of Hmonene; boiling point 
74°to 76^ at i6mm, = — 105,68°, and [a]p= — 125,5°, melting 
point of the nitrosochloride 103° to 105°. In the third fraction, which 
represents 20^/q of the oil, and which boils at 110° to 116° (at 16 mm), 
a body Cj^oH^gO could be detected, which is probably identic with 
myristicol. 
We ourselves distilled the oil of Monodora myristica Dunal about 
a year ago, when a yield of 5,37^/0 was obtained. The constants of 
the oil were dj^go = 0,859; — — 117^40'^ ^^id number = 1,36; 
ester number = 3,4; ester number after acetylation 27,11. Soluble 
in about 4 volumes and more 90^/q alcohol. 
It consisted chiefly of phellandrene. The melting point of the 
nitrite recrystallised from acetic ether, was found at 114° to 115°. 
Mustard Oil, artificial. Our participation in the competition 
in this article has reduced the value considerably. The cost at which 
we can produce it enables us to supply it to our clients on the 
most advantageous terms. 
The method for the quantitative estimation of mustard oil given 
in the German Pharmacopoeia, has been tested by R. Firbas^), who 
found that the decomposition of the thiosinamine silver compound is 
not fully accomplished within 24 hours in the cold. By applying heat, 
he obtained values which were higher in proportion to the period 
during which the substance had been heated, but he leaves it an 
open question whether the increase in the values may not be partly 
due to the constituents of mustard oil (such as carbon disulphide) 
which become decomposable only at a higher temperature and by a 
prolonged application of heat. 
According to examinations made by Schlicht^), the methods 
hitherto employed for the estimation of mustard oil in mustard seed, 
which have also been adopted by the German Pharmacopoeia IV. Ed., 
are not sufficiently exact, as for the development of the total mustard 
oil, a digestion or maceration of two hours is not sufficient, and on 
distillation a small quantity of mustard oil adheres to the condenser, 
which consequently is lost for the estimation. Schlicht therefore 
recommends the following method: The powdered seed (25 gm.) is first 
of all digested with water for four hours at the temperature of the 
room; the mixture is then heated to boiling point, and maintained at
