Med. Prop. and Action. These have been examined by Dr. Gamberini, * of Bologna, who, after considerable experience in its use, draws the following conclusions: - 1. Soda being a very common ingredient in the organism, the Iodide of its base appears to be best suited to the human system. 2. Its taste is much less disagreeable than that of the Iodide of Potassium. 3. It is less likely to occasion Iodism. 4. It is better borne than the Potassium Salt, and consequently its dose can be almost daily increased: it thus becomes a more efficient remedy. 5. It has sometimes succeeded where the Iodide of Potassium has failed. 6. It may be given daily in three equal doses, j. of the Salt to iij. of Water, increasing the strength of the solution every two or three days by six grains. Some patients have in this manner been able to take 3ij. daily without the slightest inconvenience. 7. It is admirably adapted to cases in which the corresponding Salt of Potassium is indicated. 8. It is the best substitute for Mercury.

Dose, gr. v. - gr. xv., or more.

2589. Therapeutic Uses

In Constitutional Syphilis, Gam-berini administered this salt in 116 cases: the results were, on the whole, highly satisfactory; and it was remarked that the greatest amount of benefit was derived by those who had previously undergone a protracted course of Mercury without eradicating the disease. Like other remedies of the same class, it affords no security against relapses. In nineteen cases of Secondary Syphilis affecting the bones and periosteum, this salt was administered by Dr. Daveri,t who states that, compared with the Iodide of Potassium, it is equally beneficial, whilst it is far more palatable. From the larger doses in which it can be administered, the treatment was found to be much abridged.
