One thing more:—From the flimsy manner in which most modern houses are built, where every step on the stairs, and along the floors, is felt all over the house; the higher the story, the greater the vibration. It is inconceivable how much the sick suffer by having anybody overhead. In the solidly built old houses, which, fortunately, most hospitals are, the noise and shaking is comparatively trifling. But it is a serious cause of suffering, in lightly built houses, and with the irritability peculiar to some diseases. Better far put such patients at the top of the house, even with the additional fatigue of stairs, if you cannot secure the room above them being untenanted; you may otherwise bring on a state of restlessness which no opium will subdue. Do not neglect the warning, when a patient tells you that he “Feels every step above him to cross his heart.” Remember that every noise a patient cannot see partakes of the character of suddenness to him; and I am persuaded that patients with these peculiarly irritable nerves, are positively less injured by having persons in the same room with them than overhead, or separated by only a thin compartment. Any sacrifice to secure silence for these cases is worth while, because no air, however good, no attendance, however careful, will do anything for such cases without quiet.
