arsenic in paper* hangings. 
phthisis, another of abscess in the liver, and a third from 
renal abscess associated with pyelitis. All three had been 
pining away for some time before death. The weight of each 
was considerable, and all were composed of oxalate of lime. 
They were covered with minute crystals of the same sub- 
stance, visible to the naked eye, and as they possessed a 
brown colour, they resembled in a striking degree fine 
crystals of ferruginous quartz. Dr. Gibb had reason to 
believe that the presence t>f crystals on the surface of calculi 
is rare, although they are described by Dr. Golding Bird and 
Dr. Owen Rees, and of those which do occur they are almost 
invariably the octahedral forms, both opaque and transparent, 
pf the oxalate of lime.-r-Ii^, 
A SPECIFIC FOR SCABIES. 
At the last meeting of the Academy of Sciences, Paris, 
M. Bonnet, of Epinal, sent in a paper, announcing that 
benzine is a specific for the itch. The author of the paper 
States that if benzine be rubbed on the parts affected, and 
also very slightly on the other parts of thp body, a cure will 
be effected in the course of five minutes, after which time the 
patient may take a warm bath for half an hour. Never- 
theless, in cases where the itch is accompanied with a secon- 
dary eruption, the latter will require a separate treatment.-—:

ON ARSENIC IN PAPER-HANGINGS. 
By Alfred S. Taylor, M.D., F.R.S. 
In the April number of the 4 Pharmaceutical Journal/ at 
page 520, is a note by Mr. Paul in reference to some experi- 
ments performed by Mr. Dugald Campbell on strips of paper 
coloured with emerald green. The inference drawn from the 
experiments is, that arsenic is not volatilized by causing hot 
air to pass over paper thus coloured : and your readers are 
informed that the results are contrary to the opinions
