ART, LI PROTOSULPHURET OF IRON, A NEW ANTI- 
DOTE FOR CORROSIVE SUBLIMATE. 
By M. Mialhe. 
It results from my experiments, that the protosulphuret of 
iron, a totally inert article, instantly decomposes corrosive 
sublimate, giving rise to two inoffensive compounds — proto- 
chloride of iron and deutosulphuret of mercury. This inva- 
luable property leads me to announce the protosulphuret of 
iron, in the form of hydrate, as affording by far the best anti- 
dote for this poison. 
At some future time I will publish the details of my che- 
mical researches, as well as the results of the physiological 
experiments which I propose to institute on this subject. In 
the mean time, I advance a chemico-physiological proof in 
favor of the efficacy of this antidote which appears to possess 
real value. 
Whenever a few centigrammes of corrosive sublimate is 
placed in the mouth, it immediately produces its characteristic 
insupportable metallic taste. It is then sufficient to wash out 
the mouth with the hydrated protosulphuret of iron, in the 
state of a thin pulp, a condition in which it should always be 
used, to cause all the metallic taste to disappear as if by en- 
chantment. This fact needs no commentary. It speaks for 
itself, without need of any explanation.
