She now felt a slight weakness in right arm, which from childhood up was rather weaker than the other one. After the disappearance of the induration in the mamma the arm seemed to regain its former strength and the patient felt therefore rather astonished at the reappearance of the weakness when its cause seemed removed, but it yielded readily to a mild constant current applied a few times, and some faradic shocks each time from the shoulder through the arm, and in September she went to Nizza in order to use sea-bathing, with the advice to take for a whole year one drop daily of her solution. She considered herself now well, but still her skin was flabby, especially on the hands where the epidermis often desquamated, and the nails remained hard, brittle and without lustre. I may here remark that I found repeatedly Arsenic in the urine of such patients. A case of obstinate intermittens larvata, characterized by vomiting of chyme, also yielded to _Arsen. brom._ One case more must suffice. A young man went to America but failed in his trade, and became barkeeper on a Mississippi steamer, which place he had to give up on account of intermittent fever. We find him then as hostler in Chicago where he was laid up with an attack of cholera, and as he did not fully recover his strength he returned to the old home again. When I saw him for the first time the diagnosis seemed to be first stage of Bright's disease. Anamnesis, ætiology, and present state, albumen in the urine, justified the diagnosis. Patient is pale, bloated, oedema pedum, no appetite, white tongue, thin feverish pulse, swollen spleen, watery diarrhoea alternating with constipation. Every drug produced vomiting, and he perfectly abhorred the old Quinine powders. I ordered four drops _Arsen. brom._ and a full meat diet. Improvement followed with the continuance of the treatment. After three weeks the spleen was reduced in size, his face showed better color, hardly any oedema. To strengthen the skin he was advised to take pineneedle baths, and after three months' treatment he could be discharged, a well man. He was advised to take for a few months one drop daily of his solution, and to take often an airing in the pineries which abound around Frankfort. Though he returned to America the latest reports from him are that he feels again as well as ever, but he keeps his drops about him.
