THE USE OF THE HYDRATED PEROXIDE OF 
IRON IN CASES OF POISONING BY ARSENIC. 
By F. C. Boulter, Veterinary Student, Woolwich. 
Thinking that the following facts will prove beyond aU 
doubt the value of the peroxide of iron as an antidote to 
the effects of arsenic, I send you the particulars of the case, 
to which I was called on the 2nd of June. 
Some pigs—numbering fifty-six at the time I saw them, 
upwards of ninety having previously died—the property of 
Mr. Thomas Smith, market gardener of Charlton, Kent, 
were believed to be suffering from the effects of arsenic, he 
having sent four which had died to the Veterinary College 
for analysis by Professor Tuson, who had, Mr. Smith informed 
me, pronounced them to have been poisoned with arsenic. 
Mr. Smith also told me that he suspected the poison had 
been given on the I9th of the previous month; if so, a fort¬ 
night had elapsed between that time and my seeing the 
animals. During this period, at all events, ninety had died, 
and the rest were in a very precarious condition. Being put 
in the possession of the above facts, I took steps accordingly, 
and administered the peroxide of iron (hydrated) in large 
quantities. The effect of this agent was no less remarkable 
than speedy, as the animals, which the previous day had been 
unable to walk across the sty without staggering and falling, 
now walked with a firm step, and ate up all kinds of food 
offered them with avidity, although during the previous week 
they would not touch anything. Seeing such good results, I 
continued to give the iron compound, and up to the present 
time, the lOth, only four more have died. The other pigs are 
improving every day. I opened the stomachs and also the large 
intestines of those that died, and found them highly corroded 
in patches, and, indeed, in some places quite eaten through. 
In addition to the peroxide of iron I gave the OL Lini, but I 
believe the good effects produced are mainly attributable to 
the compound of iron.
