362. In Obstinate Otorrha, Mr

Wilde§; advises the application of the Nitrate, lightly, to the external auditory passage.

363. In Coryza, M

Tessier|| speaks highly of the efficacy of pencilling the interior of the nares with a solution of the Nitrate of Silver. A similar treatment has been advocated by Dr. Lock-wood (U.S.).

364. In Insanity, Observes Dr

Copland,¶ the Nitrate of Silver has been recommended by Agricola and Kesler, and in circumstances truly indicating the propriety of tonics, and when insanity has been occasioned by depressing and exhausting causes, and in purely nervous cases, it may prove of service. It has been considered as more particularly suited to the complication of mental diseases with epilepsy. When, however, this association is dependent upon vascular or structural disease of the encephalon, little or no benefit can result from it. He adds that in one case in which he prescribed it, he was obliged to discontinue it; but that in two others, of melancholia, with chronic irritation of the digestive mucous surface, he found it of service.

365. In Hysterical Headaches, Dr

Graves* speaks highly of the efficacy of the Nitrate of Silver in considerable doses. When the paroxysm has abated, the greatest benefit, he observes, may be derived from the Nitrate, continued for five or six days at a time, in doses of gr. ss., four times or even six times daily. When the bowels are constipated, he states that there is no better combination than the Nitrate with minute doses of Pil. Coloc. Co., a formula recommended by Dr. J. Johnson, and which he has found invaluable, not merely in the headaches of hysterical young women, but in those of men, particularly the habitual stomach headache, to which delicate and literary men are so subject. In Facial Neuralgia, Romberg often found the Nitrate (gr. j. several times daily) of great, but not of permanent benefit.

366. In Chronic Arthritis, Particularly In That Of The Hip Joint, M

Jobert employs friction of the diseased part with an ointment composed of from four to twelve parts of the Nitrate, and thirty of lard. He commences with the weakest strength. A modification of this has since been very generally adopted in France, particularly by Briquet and Guerard.§ The ointment which they employ is composed of from one to five parts of the Nitrate, and thirty-two of lard. This is rubbed in daily over the diseased part, which is then covered with a poultice to promote absorption. The treatment is continued until the disappearance of the disease. The stronger ointment causes great irritation. It is reported to be a successful mode of treatment

367. In Articular Effusions, A Solution Of The Nitrate (Gr

x., Aq. fj.) or the application of the caustic in substance, drawn across the joint, previously moistened, at intervals of about a quarter of an inch apart, has been successfully employed by Dr. Moritz,|| of Coblentz. In either case the epidermis rises in blisters containing serum. When this is dissipated, the application is to be repeated. In twenty cases in which Dr. Moritz employed this treatment, a cure was effected, whether the effusion was the result of gout, rheumatism, scrofula, or wounds. In Hydrocele, Dr. Parker advocates the practice of applying the Nitrate in substance to the tunica vaginalis, after the removal of the effused fluid Iodine in ordinary cases is preferable.¶
