ART. XXVII. — ON THE PROTO-IODIDE OF IRON AND ITS 
MODE OF PREPARATION; FOLLOWED BY FORMULA 
FOR ITS ADMINISTRATION, EMPLOYED FOR SOME TIME 
WITH REMARKABLE SUCCESS IN THE TREATMENT OF 
PHTHISIS PULMONALIS. By Alphonso Ddpasquier. 
Although this paper has for its essential object the bring- 
ing forward the pharmaceutical details of the preparation of 
proto-iodide of iron which I have introduced into medical 
practice, it appears to me to be indispensable, before entering 
upon this subject, to make known the circumstances which 
have led to its use; and to give, in a few words, an idea of 
the importance of the results which I have obtained. 
This paper will therefore be divided into two parts; the 
first, historical and medical; the second, chemical and pharma- 
ceutical. 
FIRST PART.

SECOND PART. 
Researches upon the Iodide of Iron of Pharmacy ; the pre- 
paration of the Solution of Proto-iodide of Iron, and the 
formulas for its employment. 
The iodide of iron generally used, the preparation of which 
is pointed out in all the Pharmacopoeias published for the last 
ten years, is a totally different medicine, both in its chemi- 
cal nature and in its therapeutic action,ivom the proto-iodide 
of iron which I have used. It is not a proto-iodide of iron, as 
designated in all the formulae, but a mixture, of which the 
composition varies according to the care used in its prepa- 
ration and preservation. 
This iodide, the only one which had been employed by 
physicians up to the moment when I commenced to report the
