In doses of two to four drops daily, always to be taken in a full glass of water, it always shows its specific action as an antipsoricum. Herpetic eruptions and syphilitic excrescences or exanthemata dry up and heal up, while simultaneously the relaxed and thoroughly infected body steadily increases in turgor vitals. Glandular tumors and indurations of dyscrasic origin, where any other treatment has failed, are scattered by the long-continued use of my preparation. I have in suitable cases given it for years without noticing any hurtful sequelæ, and after my patients were cured I kept them under observation for years afterwards, and know, therefore, that nothing injurious followed. This cannot be said of the usual arsenical preparations, and old Heim, a great admirer of Arsenic, opposed a lengthy use of it; he rather preferred larger doses, which is rather a dangerous procedure. Given for a long time for carcinoma, it stops the rapid progress of this fearful disease, and though at the same time Chloride of arsenic was used externally, a real cure remained an impossibility. My best successes were in obstinate cases of lues inveterata, in the first stages of tabes dorsalis (ataxie locomotrice), in the reconvalescence from exhausting acute diseases, in gastric suppurations, inactivity of bowels, tardy digestion, constipation. In cases where _Chininum sulph._ failed in intermittent fevers, I prescribe _Brom. arsen._ twice daily, four drops, each time in a full glass of water, gradually diminishing it to one daily dose, and in four weeks even the most obstinate cases yielded to this treatment. The patient feels encouraged by his increasing vigor, the fever-cakes disappear, the bowels move regularly, and appetite leaves nothing to be desired. Those mean obstinate cases of intermittens larvata, often appearing in the form of unbearable neuralgiæ, yield more rapidly to it than to the Quinine. It is often quite astonishing what good results can be obtained by the daily use of only one drop of this solution, kept up for a very long time in dyscrasic constitutions, who spent a fortune to regain their health and failed with every other treatment. Its full solubility and rapid assimilation are the reason that it can be used without injury, but it must be taken largely diluted. Let me give you a few cases for elucidation.
