ROSCOE R. BELL. 
details of the operation and indications for administration are as 
follows: 
M. Durien prefers Savary’s liquid essence of mustard, on ac¬ 
count of its uniformity of strength and the facility with which it 
may be procured. He makes one or more injections, as the case 
requires, using alcohol or petroleum as a vehicle, to 1 to 2 
grammes of the essence. He finds that oedema will be produced 
over a square decimeter, and claims for his method that results 
will be obtained in ten minutes, whereas with the ordinary 
sinapism it takes about two hours, and even then not always suc¬ 
cessfully ; that as compared with the ordinary sinapism the 
engorgement is as intense, but less painful and more lasting. 
Out of twenty administrations the only complication was a small 
abscess at the point of injection, and that healed kindly. The 
operation may be performed in any region, but the best results 
follow where the skin is thin. The advantages claimed are: 
(1.) That the essence being of uniform strength, the practi¬ 
tioner is certain of the result. 
(2.) The results are immediate, a few minutes being suf¬ 
ficient. 
(3.) Saving in time ; six sinapisms can be carried in a very 
small volume. 
(4.) Economy, the price of the essence being small. 
(5.) Ho dressings are necessary. 
M. Durien employs the essence of mustard in the following 
regions for the following diseases : 
1st. In the neck, in cases of vertigo and ophthalmia. 2d. In 
the chest and sides, for heart and pulmonary troubles. 3d. In 
the abdomen, for typhoid fever, enteritis, colic, etc. 4th. In 
umbilical hernia, round the circumference of the tumor, the 
hernia being reduced in two cases about the tenth day. 
M. Cagny uses it in the same way in doubtful cases of glan¬ 
ders, to assist diagnosis. In one doubtful case, with enlargement 
of the submaxillary gland, painful swelling of the hind limbs, but 
without nasal discharge or ulceration of membrane, he made two 
injections, one on each side of chest, and in forty-eight hours the 
ulcer and nasal discharge appeared.
