ON THE LACTATE OF IRON. 
ART. XL1. — FORMULAE FOR THE EMPLOYMENT OF THE 
LACTATE OF IRON. By P. A. Cap. 
The Lactate of Iron, which the researches of MM. Gelis 
and Conte, and by the report of M. Bouillaud, has been in- 
troduced into therapeutics, has commenced to be frequently 
demanded in the shops. It will therefore be advantageous to 
fix upon some officinal formulae, which will permit practi- 
tioners to calculate easily the quantity of the salt employed 
under different: pharmaceutic forms. The following are what 
I propose: 
Pastils of Lactate of Iron, 
jfc. Lactate of iron, 30 grammes. 
Sugar, 360 " 
Mucilage of gum arab. q. s. 
Mould into lozenges, weighing 65 centigrammes, each of 
which will contain 5 centigrammes of the salt. 
Syrup of Lactate of Iron. 
Jfc. Lactate of Iron, 4 grammes. 
- Boiling distilled water, 200 " 
White sugar, 400 " 
The lactate of iron not being soluble but in 40 parts of 
boiling distilled water, a greater quantity can hardly be in- 
troduced into a syrup. This proportion is a 150th, (about 4 
grains per ounce.) The method which has best succeeded 
with me is the following: 
Triturate the salt with four times its weight of pulverized 
sugar, dissolve it rapidly in the whole of the distilled water, 
and pour the whole into a matras, which is to be placed in a 
salt bath, after having added the remainder of the sugar, broken 
into small fragments ; as soon as the sugar is dissolved, 
pour the syrup on a filter; and when it has cooled, preserve it. 
in well stopped bottles. This syrup has a light amber tint
