I have spoken of the moral conditions implied in the successful management of sick children. There are certain physical conditions no less important. The sick child should not be left in the common nursery, of which he would taint the air, while he would be disturbed by its other little inmates. He must (and of course I am speaking not of some slight ailment, but of a more serious indisposition) be in a room by himself, which should be kept quiet and shaded, and at a temperature which should not be allowed to fall below 60 deg. if the chest is in any way affected, nor to exceed 55 deg. in other cases, and this temperature should always be measured, not by guess, but by the thermometer hung close to the child's bed. The room is to be shaded, not by curtains round the bed--for, save in special circumstances, curtains should be banished from the nursery--nor by closed shutters which exclude both light and air, but by letting down the blinds, so as to have a sort of twilight in the room, and by shading any light which at night may be burned in the apartment; while whether by day or night the child should be so placed that his face shall be turned from the light, not directed towards it. The room should be kept quiet, and this requires not only general quiet in the house, but quiet in the movements of all persons in the room; speaking, not in a whisper, but in a low and gentle voice; walking carefully, not in a silk dress nor in creaky shoes, but not on tiptoe, for there is a fussy sham quietness which disturbs the sick far more than the loudest noise. Little precautions, so trifling that few think of noticing them, have much to do with the quiet of the sick-room, and consequently with the patient's comfort. A rattling window will keep a child awake for hours, or the creaking handle of the door rouse it up again each time anyone enters the room; and to put a wedge in the window, or to tie back the handle, and so quietly open and close the door, may do more than medicine towards promoting the child's recovery. There can, however, be no abiding quiet without a well-ordered room, and the old proverb carried out, 'A place for everything, and everything in its place.' A table covered with a cloth so that things may be taken up and put down noiselessly, and set apart for the medicine, the drink, the nourishment, cups, glasses, spoons, or whatever else the patient is in frequent need of; with a _wooden_ bowl and water for rinsing cups and glasses in, and a cloth or two for wiping them, will save much trouble and noise, and the loud whispers of the attendants to each other, 'Where is the sugar? where is the arrowroot? where did you put down the medicine?' of which we hear so much in the sick-room, so much especially in the sick-room of the child, who is unable to tell how extremely all this disturbs him.
