Having succeeded so well in paralysis, Dr. Manson was induced to try the effects of iodine in chorea, which he thinks is more closely allied to palsy than is supposed, and is linked to it by that species of the disease called shaking palsy. Of chorea treated with iodine, and showing the efficacy of the remedy, Dr. Manson details eleven cases, and concludes this section with a tabular view of 72 cases treated at the General Hospital near Nottingham, between the 6th of October, 1812, and the 5th of October, 1824. In all the cases detailed by our author, the iodine was administered after purgatives, and throughout the treatment, the bowels were carefully regulated by aperient medicines.

Dr. Manson next records the results of his experience with iodine in scrofula—detailing three cases of scrofulous enlargement of the conglobate glands—two of scrofulous ulcers, and four of scrofulous ophthalmia; in all of which, the most beneficial effects were obtained. Our author details eleven cases of fistula lachrymalis, in which iodine produced the happiest results. He was led to prescribe iodine in this disease from the circumstance, that one of the individuals to whom he gave it for paralysis, laboured under the fistula, and was promptly relieved of it, whilst under the use of the remedy.

Dr. Manson has likewise detailed nine cases of deafness cured, or greatly relieved, by iodine. In most of these cases, the disease originated from obstruction of the Eustachian tube, the consequence of swelling of the tonsils, or of the membrane of the tube itself, from previous inflammation.

Seven cases of dysphagia, eleven of white swelling, four of morbus coxarius, and eleven of distortion, form the subjects of the four succeeding sections. The medicine in all these cases, manifested so very decided a power in arresting the progress, and even in curing the disease, that we think ourselves safe in recommending a trial of it in similar cases. As the iodine, however, is a powerful stimulant, we would advise it not to be prescribed when there exists any fever, and especially when there are any decided signs of gastric irritation, as it would be likely to aggravate it.

23. Non-mercurial treatment of Syphilis.—In the first number of this Journal, we inserted an essay on this subject, by Dr. Thomas Harris, of this city, in which the author confirms, by the results of his public and private practice, the statements of the British army surgeons respecting the efficacy and safety of the non-mercurial treatment. Since that period, having noticed that, by the worthy editor of a respected cotemporary, it is asserted that though mercury fails, "yet from the most ample experience in Europe, the present practice of Paris, England, Ireland, and the Continent generally, we must lean to the idea, that its use, under proper regulations, must be always adopted, as the only safe mode of cure in these diseases," we deem it but justice towards Dr. H. to call the attention of our readers to the result of the extensive experience of some physicians on the continent of Europe. Not to mention Broussais himself, who appears to have rejected mercury almost entirely in the treatment of primary or secondary symptoms, we may cite Mr. Richond, who reports that he treated, at the military hospital of Strasburgh, nearly 3000 cases of syphilis in all its grades, the vast majority of which were completely cured without mercury, and simply by means of antiphlogistics, emollients, and revulsives. Mr. Richond, besides some essays in the Archives Medicales, and a summary of his experience in the preface to his work on apoplexy, has lately published an elaborate work on the subject. In the October number of the Annales de la Médecine Physiologique, Mr. Becquart of the military hospital of Bayonne, details twenty-six cases of gonorrhœa, inflammation of the testicles, chancres on the glans and lips, buboes, excrescences around the anus, &c., all of which were cured without mercury, and with the same remedies as were employed by Mr. Richond. We might adduce the testimony of other French physicians, and particularly of M. Begin, but we deem it unnecessary, as the above will be sufficient to show that in France the practice meets with the support of many very intelligent physicians. We annex the conclusions of Dr. Otto of Copenhagen, drawn from an extended personal experience, and from his researches on the subject. Dr. Otto's essay is contained in a late number of Gräafe's and Walther's Journal, and the conclusions are published in the Edinburgh Medical and Surgical Journal. Dr. O. remarks:

1. That the cure of syphilis, without mercury, has been asserted by so many authorities, that the fact can no longer be doubted. If, then, the disease could formerly be cured without mercury, it may certainly now be much easier, as it has lost much of its violence and obstinacy.

2. Syphilis can undoubtedly be radically cured in this manner; but then the cure is of longer duration, and the diet requires considerable restriction.

3. The secondary symptoms, and a return of the complaint, are certainly more frequent; but the symptoms are not so difficult of removal; and the treatment has a much more speedy effect.

4. As the treatment without mercury requires a longer time, it appears more practicable in hospital than in private practice; and on the other hand, the patient can be better watched in a hospital, which, on account of the diet, is of great importance.

5. As ulcers on the genitals are often not syphilitic, and the use of mercury is contraindicated from a predisposition to scrofula or phthisis existing in the individual, it is consolatory to learn from the results of experience, that this medicine is not always necessary, and that a radical cure, by more simple and innocent means, can sometimes be effected. Where, however, the physician is anxious to avoid the possible evils which mercury is capable of producing, and also to prevent loss of time, there remains a middle way, namely, to employ mercury, whose specific action can scarcely be denied, in moderate doses.
