 Dehaen relates a distinct example of this disorder occurring in a female who took a small quantity of arsenic by mistake. The ordinary signs of inflammation were soon subdued, and for three days she did well; but on the fourth she was attacked with cramps, tenderness, and weakness of the feet, legs and arms, increasing gradually till the whole extremities became at length almost completely palsied. At the same time the cuticle desquamated. But the other functions continued entire. The power of motion returned first in the hands, then in the arms, and she eventually recovered; but eleven months passed before she could quit the hospital where Dehaen treated her.

An excellent account of a set of similar cases has been given by Dr. Murray of Aberdeen. They became the subject of judicial inquiry on the trial of George Thom, who was condemned in 1821 at the Aberdeen autumn circuit for poisoning his brother-in-law. Four persons were simultaneously affected about an hour after breakfast with the primary symptoms of poisoning with arsenic, and some in a very violent degree. But besides these symptoms, in all of them the muscular debility was great; and in two it amounted to true partial palsy. One of them lost altogether the power of the left arm, and six months after, when the account of the cases was published, he was unable to bend the arm at the elbow-joint. The other had also great general debility and long-continued numbness and pains of the legs.

An interesting case of the same nature with these was lately submitted to me on the part of the crown. A man after taking arsenic was attacked with vomiting, purging, and other symptoms of abdominal irritation, which were mistaken for dysentery. Five days afterwards he began to suffer also from feebleness of the limbs; amounting almost to palsy. Subsequently an improvement slowly took place; but he continued to suffer under irritative fever, diarrhœa, and faintness. Several weeks later the diarrhœa abated, but he had great stiffness, numbness, and loss of power in the joints of the hands and feet. Two months after he first took ill, and while he was slowly recovering from this paralytic affection, arsenic was again administered and proved fatal in eighteen hours.

Another, somewhat similar to the preceding, has been related by M. Lachèse of Angers. Two people took about half a grain in soup twice a day for two days, and were attacked with the usual primary symptoms. One of them died in ten weeks, gradually worn out, but without any particular nervous affection. The other was seized with convulsions, and afterwards with almost complete palsy of the limbs. —A well-marked case of the same nature has been noticed by Professor Bernt. It was the case formerly alluded to as arising from an overdose of the arseniate of potass. The paralytic affection consisted in the loss of sensation and of the power of motion in the hands, and of the loss of motion in the feet, with contraction of the
