NEW METHOD FOR PREPARING AND EXHIBITING PROTIODIDE OF IRON. BY M. H. BONNEWYN.

Several methods have been proposed for the preparation and exhibition of protiodide of iron, all of which are, as far as I am acquainted with them, subject to many inconveniences and objections. It is on this account that I offer to my fellow-laborers a new method, which both on account of its uniformity of action and facility of ad­min­i­stra­tion, deserves to be adopted universally.

Every practical man knows that all preparations of protiodide of iron are bad, for instance, syrupus ferri iodidi is a medicine which is generally disliked, and in some individuals causes nausea and even vomiting. The pilulæ ferri iodidi {251} likewise disagree with some constitutions, and when they seem to agree, they never produce the same regular effects even if prepared at the same labratory. According to trials made by an experienced physician, who has administered the protiodide, prepared according to my method, I am assured that this remedy prepared by a double decomposition in the stomachs of the patients, has always agreed with them, and produced more constant and salutary effects. It is already a well-known fact, that the iodide of iron in its incipient state is better assimilated by the organs.

No. 1. Dissolve one gramme of iodide potassium in 300 grammes of water. No. 2. Take sulphate of iron 11⁄2 grammes; make a powder and divide into eighteen equal parts. Dissolve one of the powders in a large table-spoonful of sugared water before swallowing it; take immediately afterwars, one table-spoonful of the solution.

It is evident that by this operation, each time their is produced in the stomach one grain, or about five centigrammes of iodide of iron in its incipient state.

Although these proportions do not correspond absolutely, but only approximately with their chemical equivalents, nevertheless, their effects answer fully the purposes both of the chemist, and Physician.—Annals of Pharmacy and Practical Chemistry.
