ART. LX. — SOLUTION OF IODIDE OF IRON. 
By William Procter, Jr. 
At page 13th of the present volume, a process was detailed 
for preventing the decomposition of solution of iodide of iron, 
by the addition of saccharine matter. Several who have em- 
ployed it having stated objections, it was found on inquiry 
that either sugar or impure honey had been used in its forma- 
tion. The paper above alluded to says, that either sugar, 
uncrystallizable honey, or uncrystallizable sugar may be 
used, but expressly gives the preference to the two last, as 
having the most power. Honey, when properly prepared, 
owing to its light color, is preferable to molasses. The ob- 
ject of preparing it is to deprive it of acidity, as well as color. 
The following formula, recommended by the committee of the 
Philadelphia College of Pharmacy, on the U. S. Pharmacopoeia, 
is an excellent one, and yields a product that fully answers 
the proposed end. 
Take of honey Oss. 
" diluted alcohol Oj. 
" prepared chalk §ss. 
Mix the honey with the diluted alcohol, add the prepared 
chalk, agitate them well together, and heat the mixture till it 
boils — then filter, and by means of a water bath, evaporate 
the clear solution to the consistence of honey. 
By pursuing this method for the preparation of the honey, 
this unstable preparation of iron is rendered permanent. 
Note. — In the tenth volume, page 274 of this Journal, was published 
an article exhibiting a new process for the preparation of tincture of mu- 
riate of iron. In copying the paper, an error was made by which the 
quantity of tincture directed to be formed with two ounces of hydrochloric 
acid was nineteen ounces, instead of nine and a half ounces, the correct quan- 
tity. Those who were subscribers to the Journal at that time will please 
to note this fact, at the page where the error occurred.
