DETECTION OF ARSENIC BY MEANS OP COPPER. 269 
charge copious, and his sufferings from soreness and itching 
were extreme, so that after persevering steadily for three 
days, he was obliged to give it up. 
About the same period, I was consulted by my friend Mr. 
French, of Great Marlborough Street, respecting a patient 
of his who had a cancerous sore upon the right leg. Here 
I advised a trial of the above lotion ; but after applying it 
assiduously during three consecutive weeks, no improvement 
could be perceived. Ibid. 
ART. LXV.— NOTICE OF THE METHOD OF DETECTING 
ARSENIC BY MEANS OF COPPER, PROPOSED BY M. 
HUGO-REINSCH. 
By Louis- Victor Adouard of Beziers. 
In theViumber of the "Journal de Chimie Medicale" for 
January, 1843, M. Hugo-Reinsch proposes a new method 
for detecting arsenic, which he assures us rivals in sensibility 
the process of Marsh. To convince myself of this fact, the 
following experiments were undertaken. 
Dr. Guy had employed with success at Beziers, Fowler's 
arsenical solution in certain eruptions. A smith, aged 30 
years, by the advice of his physician, took this solution for 
several days, commencing with two drops morning and 
evening, and increasing to twelve. 
I requested the smith to send me the urine which passed 
at night and morning, or after each dose of the arsenical so- 
lution. I received in a bottle 1200 grammes of urine, per- 
fectly limpid, and slightly acid. 
This I divided into two parts ; one part was treated by 
Orfila's process — viz. incineration with nitrate of potassa.
