The following case exhibits some practical points exceedingly worthy of record, and displays besides, in a remarkable degree, the control a lunatic disposed to suicide acquires over himself, his conversation, and conduct, when he wishes to lull suspicion to sleep. In this instance, says Dr. Burrows, who relates the particulars of the case, a most judicious physician, and those in whom he had confidence, all experienced in the phases of this wonderful malady, insanity, and its no less wonderful concomitant, suicide, were completely deceived. A medical friend of the Doctor’s, travelling over Shooter’s Hill, observed a gentleman walking up it, his carriage following him. When opposite to each other, the stranger suddenly fell on his knees in the dirt, and lifted up his hands, as if in earnest prayer. The friend stopped his post-chaise at so extraordinary a sight, and soon found by his looks and manners that the poor gentleman was insane. He immediately accompanied him back to London, and placed him under Dr. B.’s care till his relations were informed of his state. The history of the case was this:—The patient was a cavalry officer of rank, aged thirty-five, and had particularly distinguished himself at the recent battle of Waterloo. On that occasion he had two horses killed under him, and was himself wounded in four places. He was first struck on the crown of his helmet by the splinter of a shell, which wounded the scalp and stunned him; he was next shot through the fleshy part of the thigh by a grape shot, which at the same time killed his first horse; from these two wounds he lost much blood. Whilst lying under his second horse, he was pierced in the groin by a lance; and in this helpless condition he received from a French drummer, who was rifling the dead and dying, a violent blow on the temple from the butt-end of a musket, from the effects of which, he remained some time insensible. He was afterwards conveyed in a most deplorable state as a prisoner within the French lines, and though released the same evening by the victorious allies, a long while elapsed before his wounds and exhausted condition received any attention. He inherited a predisposition to insanity, and was naturally reserved, diffident, and taciturn, but affectionate and generous. When he recovered from his wounds, he often complained of pains in his head; and it was observed that his temper became fretful and suspicious; that he slept ill, was depressed in spirits, and courted solitude. These symptoms increased latterly. At length he imagined himself the sport of his brother officers, and many other delusions arose.
