"On the 12th of April, the patients of No. 7 ward (twenty-five in number) having had their supper, were going to bed at a quarter before eight o'clock--all of them, being more or less refractory, have a single bedroom each. The attendant, in seeing them to bed, inadvertently locked up two (B. and W.) in one room; he stated that, observing the day-clothing of all outside their doors, he supposed that the patients were in their rooms, and, therefore, did not take the precaution to look into them. The room No. 19 was the one usually occupied by W., a man of exceedingly clean habits, of a mild expression of countenance, but very violent, prone to strike suddenly and without provocation any person within reach of him; so frequently had he done this, that he was not allowed to sit near other patients, even at meals, but took his food apart from them at a side-table. B., whose room was No. 10, directly opposite to No. 19, was occasionally violent, always dirty in his habits, and destructive of clothing. It is supposed that this man entered No. 19 room by mistake, and that his presence there excited the homicidal tendency of the other into action. What is known is, that the night-attendant, when he visited the ward at half-past ten o'clock, and went as usual to the room No. 10, found it unoccupied, and the patient's clothes outside the door; then hearing a noise in the room 19, he opened the door, and saw B. extended at full length on his back on the floor, naked and quite dead. W. came out of the room in his shirt immediately the door was opened, and, pointing to B., said, 'That fellow will not allow me to sleep.' There was a mark round B.'s neck as if caused by a cord, which had produced strangulation, and a mark of a severe blow on the top of the nose, and of a bruise on the chest: the bedclothes were in great disorder; amongst them were found the shirt and flannel of B.; one sleeve of the former was twisted like a rope, as if W. had strangled B. with it."
