M. Bouchardat’s well-known compact little yearly volumes are always welcome, and always useful; and this year the _résumé_ includes a rather unusual number of interesting matters. The first thing which deserves notice is the recent researches on the therapeutic action of arsenic in phthisis; a subject which we have for some time past desired to discuss in this journal, but have been prevented by want of space and time. The very able paper of M. Moutard-Martin, read before the Academy in November last, called forth a report from M. Hérard, which speaks in such strong eulogy of the remedy as used in the manner and under the conditions laid down by M. Moutard-Martin, that we are considerably surprised to observe the small amount of notice which has been given to the subject in England. Arsenic has of course been long known as a tonic more or less applicable to phthisis, as to other states of debility. But the points so sharply brought out by the French author—the limitation of the therapeutic action of arsenic to the non-febrile periods and cases, and (on the other hand) its extraordinary efficacy within these limits, in restoring flesh and strength and general health, and wonderfully amending the state of the lungs themselves—are so important that they demand the serious and immediate attention of English physicians. M. Moutard-Martin employs the remedy in pills, as being more convenient than the liquid form; each of these pills (_granules de dioscoride_) contains a milligramme (·00156 of a grain) of arsenious acid, with manna and honey. Another matter which deserves notice, and had escaped ours, is the experience of M. de Beaufort as to the efficacy of iodide of potassium in diseases of the lachrymal apparatus. This observer began by applying the treatment to comparatively recent and slight cases of obstruction of the sac and nasal duct, the result of coryza, chronic conjunctivitis, &c. Obtaining a speedy cure in several such cases, he proceeded to try it even in instances where a tough fibrous stricture had existed for a long time. Even in such apparently unlikely circumstances, he has twice obtained success by the treatment. Where there is lachrymal fistula, following an abscess of the sac, the iodide is also very useful, but its employment should be accompanied by applications of tincture of iodine.
