HOT AIR AND COOL ROOMS.

Because, when the air of the streets marks 30 or 40 degrees on the Fahrenheit tcale, a room overmanned by a fire can be coaled by opening the windows, the average British householder adopts the ready conclusion that whenever a room feels hot the way to cool it is to letin the external air. Accordingly in these piping times he, and still more often she, opens the windows on the sunny side of the house, and lets in air of a temperature varying from 100 to 120 degrees, or so. Then, becamse in a very short time the room, naturally enough, becomes much hotter than it was, it if considered that the windows are not opened widely enough, and the supposed error being re» meditd, a still larger quantity or hot air is then lei in. And so we find Materfamilias sitting with a very light muslin upon her frame, and a great deal of perspiration upon her, upper lip; her face the colour of an Orleans plum, and her coridi* tion of mind to the last degree dejected, simply because she persists in disregard" ing the moat elementary principles of na« tural philosophy. We tell her that if she j will open the windows on the shady side of the house only, and keep the others closely shut, her dwelling will be at least not hotter than the shady side of the street, whereas by her. arrangment it acquires the heat of the sunny side. We tell her also that if her heuse be larga and the inmates few, she may live in a dalight•ful state of coolness by only opening the windows at night, and keepiag them closed during the day. Her house: will then be 10 or 15 degrees lower in^ t«mpe« rafcuro than the streets, and convey very much the refreshing effects of a cool bath upon entering it. We tell Her all this; and she is very much interested. At our rest visit we find every window open, and the house full of red hot air. "It stands to reason," she says, triumphantly, "that you cannot possibly cool a jiouse without plenty of ventilation."—Lancet.
