contained no arsenic. In this experiment, the quantity of 
arsenic operated on in the substance of the stomach could 
not have exceeded one eighth part of a grain. 
2. The liver .—Sixty grains of the dried liver of a person 
who died about five years since from the effects of arsenic, 
were broken up and distilled with hydrochloric acid. A 
slightly coloured, offensive liquid was obtained in the receiver, 
which yielded arsenic readily by the methods described, in 
all the forms in which arsenic admits of recognition. The 
residue in the retort contained no arsenic. 
3. A poisoned lozenge .—This was an ordinary sugar-lozenge, 
poisoned with a grain of arsenic. It was distilled with 
hydrochloric acid. Arsenic was abundantly procured in the 
distillate, which v T as of a yellowish-brown colour, arising 
from the presence of some organic matter. This was not, 
however, in sufficient quantity to interfere with the subse¬ 
quent stages of the analysis. The sugar darkened consider¬ 
ably in the retort, and gave much froth. The process of 
distillation was found to be more troublesome w ith saccharine 
than with other kinds of organic matter. A trace of arsenic 
was detected in the residue in the retort, showing that in this 
instance, by one distillation, the arsenic had not been entirely 
separated. The quantity, was, however, so small that it was 
not considered necessary to resort to a second distillation. 
4. Arsenical paper-hangings .—About half a square inch of 
a green paper, coated w ith the aceto-arsenite of copper, gave, 
on distillation with hydrochloric acid, a clear acid distillate, 
from which arsenic w’as readily procured in its usual forms.

We extract the following from Dr. Letherby’s report on 
the sanitary condition of the City of London for the quarter 
ending the 24th of June last. It will be seen that even now 
a considerable amount of unwholesome meat finds its way to 
the market, to the detriment of the health of the poorer classes, 
but it is gratifying to find that, by the vigilance of the in¬ 
spectors, the nefarious practice has received a salutary check. 
After referring to the state of the public health, and the 
various causes, more especially the supply of water to the in¬ 
habitants of the city, which exercise an important influence 
over it, Dr. Letherby goes on to remark that—
