In sickness select a large and lofty room; if in the town, the back of the house will be preferable--in order to keep the patient free from noise and bustle--as a sick-chamber cannot be kept too quiet. Be sure that there be a chimney in the room--as there ought to be in _every_ room in the house--and that it be not stopped, as it will help to carry off the impure air of the apartment. Keep the chamber _well ventilated_, by, from time to time, opening the window. The air of the apartment cannot be too pure; therefore, let the evacuations from the bowels be instantly removed, either to a distant part of the house, or to an out-house or to the cellar, as it might be necessary to keep them for the medical man's inspection. Before using either the night-commode, or the _pot-de-chambre_, let a little water, to the depth of one or two inches, be put in the pan, or _pot_; in order to sweeten the motion, and to prevent the faecal matter from adhering to the vessel. Let there be frequent change of linen, as in sickness it is even more necessary than in health, more especially if the complaint be fever. In an attack of fever, clean sheets ought, every other day, to be put on the bed; clean body-linen every day. A frequent change of linen in sickness is most refreshing. If the complaint be fever, a fire in the grate will not be necessary. Should it be a case either of inflammation of the lungs or of the chest, a small fire in the winter time is desirable, keeping the temperature of the room as nearly as possible at 60 degrees Fahrenheit. Bear in mind that a large fire in a sick-room cannot be too strongly condemned; for if there be fever--and there are scarcely any complaints without--a large fire only increases it. Small fires, in cases either of inflammation of the lungs or of the chest, in the winter time, encourage ventilation of the apartment, and thus carry off impure air. If it be summer time, of course fires would be improper. A thermometer is an indispensable requisite in a sick-room. In fever, free and thorough ventilation is of vital importance, more especially in scarlet fever; then a patient cannot have too much air; in scarlet fever, for the first few days the windows, be it winter or summer, must to the widest extent be opened. The fear of the patient catching cold by doing so is one of the numerous prejudices and baseless fears that haunt the nursery, and the sooner it is exploded the better it will he for human life. The valances and bed-curtains ought to be removed, and there should be as little furniture in the room as possible.
