Plumbum iodatum

Volume I — Special Symptomatology

(Plumbi Iodium.)

Pharmacology. — Dissolve one part Nitrate of lead in twenty parts distilled water, and then mix with solution of one part iodide of potassium and eight parts of water; allow the precipitate to subside, throw it on a filter, wash it well with cold water, and dry with a gentle heat. The product will be one and two-fifths parts. Acetate of lead cannot be substi

The Iodide of Lead is an odorless, fine yellow powder, without taste, soluble in 1.990 parts of cold and 1.330 parts of boiling water. The solutions are colorless, the hot one depositing, as it cools, large brilliant golden scales, soluble in 4500 parts 80$ cold alcohol, a trifle less of hot alcohol, forming a pale straw-colored solution.

Officinal Preparations. — Triturations only.

Analogues. — Kali bichromicum, Mercur. iod., Phytolacca, Conium, Laches is. Apis, etc.

° Enlargement of the tonsils.

° Diphtheria.

There are others of the Iodides which may become valuable remedies. One of them, the
