Baths containing from 15 to 30 gr. of arseniate of soda, with a few ounces of the carbonate of soda, have been well spoken of by Dr. Gueneau de Mussy, as relieving both the pain and the deformity consequent upon rheumatic arthritis. There is some evidence in favor of the internal use of the remedy for this malady (v. p. 51).
The therapeutical powers of arsenic, which are many and various, may be traced along the same lines as its physiological action, and without implying any definite limits as to the pathology of the under-mentioned diseases, we may, for the sake of clearness, arrange them in four groups for consideration in detail: - (a) General or blood-diseases, such as intermittent fever, phthisis, struma, lymphoma, anaemia, chronic rheumatism, diabetes; (b) more specially nerve-disorders, neuralgias, asthma, chorea, tremor; (c) disorders connected mainly with capillary congestion, cerebral, renal, uterine, or cutaneous; (d) disorders affecting chiefly mucous membranes, coryza, chronic bronchitis, dyspepsia, gastric catarrh, vomiting, diarrhoea, English cholera, gastric ulcer.
1 Of the older writers on this subject, Melchior Frick, and the two Plencitz, of Vienna, deserve mention. The former says - "Experientia nos docebit, arsenicum in febribus intermittentibus adhibitum omnes eas dotes possidere, quibus optima reme-dia praedita esse debeat" (Paradoxa de Venenis, 1710). Of the practice of the latter at the Orphans' Asylum, Harless reports - "Ejusque (arsenici) usu in millenis fere febrium intermittentium casibus, raro frustratos fuisse affirmant."
