REMEDY FOR ARSENICAL PREPARATIONS. 55 
expressing the chemical constitution of this substance, or of 
furfuroamide, as the author calls it, is C 15 H 6 N O 3 , and it 
is classed by him with the amides. The oil itself appears 
to be identical with the substance described by Dr. Sten- 
house under the name of artificial oil of ants. Another 
substance, isomeric with the amides, and of which the for- 
mula is C 30 H 12 N 2 O 6 , was obtained by the author, and 
termed by him furf urine, and found to have the proper- 
ties of a vegeto-aikali, and to form saline compounds with 
various acids.

ART. XVI. — ACETATE OF IRON AS A REMEDY FOR 
ARSENICAL PREPARATIONS. 
The hydrated peroxide of iron is of admitted efficacy in 
cases of poisoning with uncombined arsenious or arsenic acid ; 
but according to the experiments of Duflos, it is quite ineffec- 
tual when these acids are combined with bases, as for example, 
Fowler's solution, or arsenite of potash, or arseniate of potash, 
Which last is frequently employed in calico-printing, and is 
consequently easily procured. 
In the uncertainty in which the practitioner may be placed 
as to whether the arsenical poison be free or combined, it is 
very important to administer the oxide of iron in such a form 
as to produce a favorable result : to this end it is convenient 
to employ the peracetate of iron. 
This compound may be prepared by adding to the hydrated 
peroxide of iron obtained from the decomposition of four 
parts of liquid perchloride of iron, three parts of acetic acid of 
density 1.06, and . sufficient water to make up 16 parts.
