gradual exhaustion of the vital powers, ending fatally in two years.[1] M. Errard of Injurieux in France lately met with two cases, where, in consequence of a freshly blistered surface being dressed with a cerate made with the stearine of arsenicated candles (see p. 256), local pain, nausea, pain in the stomach, urgent thirst, redness of the tongue, involuntary contractions of the muscles of the extremities, and weakness and irregularity of the pulse came on; and one person died within twenty-four hours, while the other recovered, chiefly because the dressing caused so much pain that the patient could not keep it on long.[2]
Next as to ulcers; M. Roux has noticed the case of a girl, who was killed by the application of the arsenical paste to an ulcer of the breast, and in whom the constitutional symptoms were strongly marked, although the quantity of the poison must have been very small. The preparation used, which contains only a twenty-fourth of its weight of arsenic, was applied for a single night on a surface not exceeding an inch and a half in diameter. Yet she complained next day of violent colic and vomited frequently, the countenance soon became collapsed, and she died two days afterwards in great anguish.[3] Another instance of the like kind is related in the Annales d'Hygiène, where death arose from an arsenical ointment ignorantly applied for scirrhous breast over a large surface of the skin stripped of the cuticle by a blister. The particular symptoms and their duration are not stated; but there was violent irritation of the stomach.[4] Another fatal case, related by Dr. Küchler, arose from the application of Frêre Cosme's powder to a soft fungoid tumour on the temple, which discharged serum usually and blood upon slight pressure. About a drachm and a half of arsenic mixed with fifteen grains of other powders was applied. Severe inflammation spread round the tumour next day; and soon afterwards, the patient was attacked with great difficulty of breathing, thirst, pains in the belly, and purging, then with difficulty in swallowing from swelling of the base of the tongue, delirium, cold sweating, and extreme debility; and death ensued in four days.[5]
There is a singular uncertainty in the effects of arsenic when applied to ulcerated surfaces. Some persons, like Roux's patient, are obviously affected by a single application; while others have had it applied for a long time without experiencing any other consequences than the formation of an eschar at the part. Two causes have been assigned for these differences, and probably both are founded on fact. One, which has been assigned by Mr. Blackadder, is the relative quantity of arsenic applied. He says he never witnessed but one instance of its acting constitutionally, although he often applied it to sores; and he imputes this success to his having always used a large quantity. For he considers that by so doing the organization of the
