- getic, however, when applied to the more delicate skin of the human
subject. Some experiments were made by Mr. Sherwen on himself with the view of proving this;[1] but they are not satisfactory. The following facts, however, will show that it may produce through the sound skin all the ordinary signs of poisoning. Desgranges, a good authority, relates the case of a woman who anointed her head with an arsenical ointment to kill lice, and, after using it several days, was attacked with erysipelas of the head and face, attended with ulceration of the scalp, swelling of the salivary and cervical glands, and inflammation of the eyes. There were likewise violent constitutional symptoms,—much fever, fainting, giddiness, vomiting and pain in the stomach, tenesmus, and ardor urinæ, tremors of the limbs, and even occasional delirium. Afterwards the whole body became covered with an eruption of white papulæ, which dried and dropt off in forty-eight hours. She recovered gradually; but appears to have made a narrow escape. Her hair fell out during convalescence.[2] A similar instance is recorded in the Acta Germanica for 1730. A schoolboy having found in the street a parcel of arsenic, his mother mistook it for hair powder; and as he had to deliver a valedictory speech at school next day, she advised him to powder himself well with it in the morning. This he accordingly did. In the middle of his speech he was attacked with acute pain of the face; and a fertile crop of pustules soon broke out upon it. The head afterwards swelled much, and the pustules spread all around it; he was tormented with intolerable heat in the scalp; and the hair became matted with the discharge into a thick scabby crust. This crust separated in a few weeks, and he soon recovered completely.[3] Schulze, a German physician, has related no fewer than five cases of the same description, all arising from arsenic having been mistaken for hair-powder; and one of them proved fatal. Two of the cases were slight. The other persons had the same violent inflammation of the head as Desgranges's patient and the German schoolboy. In the fatal case death took place in twenty-one days; and on dissection, besides other morbid appearances, the scalp was found gangrenous and infiltered with fluid blood, and the stomach much inflamed.[4] The two survivors, who were severely ill, it is well to add, were not attacked with the erysipelas of the scalp till six days after they powdered themselves. Sproegel mentions a fatal case from fly-powder having been applied in like manner to the head; and Wibmer quotes another, but not fatal, where from the same cause great swelling of the head and face arose, followed by erysipelas of the face, neck, and belly, and a papular eruption on the hands which continued five days.[5]
From the statements now made, it is evident that arsenic applied to various parts of the external surface and natural apertures of the
