the air has never been polluted by the breathing of human beings, you will observe a close, musty smell of corrupt air, i.e. of air unpurified by the effect of the sun's rays. The mustiness of dark rooms and corners, indeed, is proverbial. The cheerfulness of a room, the usefulness of light in treating disease is all-important.
A very high authority in hospital construction has said that people do not enough consider the difference between wards and dormitories in planning their buildings. But I go farther, and say, that healthy people never remember the difference between bed-rooms and sick-rooms, in making arrangements for the sick. To a sleeper in health it does not signify what the view is from his bed. He ought never to be in it excepting when asleep, and at night. Aspect does not very much signify either (provided the sun reach his bed-room some time in every day, to purify the air), because he ought never to be in his bed-room except during the hours when there is no sun. But the case is exactly reversed with the sick, even should they be as many hours out of their beds as you are in yours, which probably they are not. Therefore, that they should be able, without raising themselves or turning in bed, to see out of window from their beds, to see sky and sunlight at least, if you can show them nothing else, I assert to be, if not of the very first importance for recovery, at least something very near it. And you should therefore look to the position of the beds of your sick one of the very first things. If they can see out of two windows instead of one, so much the better. Again, the morning sun and the mid-day sun — the hours when they are quite certain not to be up, are of more importance to them, if a choice must be made, than the afternoon sun. Perhaps you can take them out of bed in the afternoon and set them by the window, where they can see the sun. But the best rule is, if possible, to give them direct sunlight from the moment he rises till the moment he sets.
Another great difference between the bed-room. and the sick-room. is, that the sleeper has a very large balance of fresh air to begin with, when he begins the night, if his room has been open all day as it ought to be; the sick man has not, because all day he has been breathing the air in the same room, and dirtying it by the emanations from
