In fact such a condition of the air would not be unlike the effects of higher altitudes. Some investigations recently conducted at the U.S. Experiment Station for human nutrition, have shown the utter misconception of the old idea of ventilation.
There had not been a single case of it west of the high water mark made by the terrible freshet of the previous spring. We sent brandy and wine and beef-tea into the poor, comfortless, grief-stricken houses; and we said at tea-time that it was strange, people would persist in living down under the bank: what could they expect? and besides, they were "so careless about drainage and ventilation."
Now the first problem in housebuilding is to combine the advantage of shelter with the fresh elasticity of outdoor air. I am not going to give here a treatise on ventilation, but merely to say, in general terms, that the first object of a house builder or contriver should be to make a healthy house; and the first requisite of a healthy house is a pure, sweet, elastic air.
Tidy's table, each ordinary jet of common gas contributes to the air of a room sixteen by ten feet on the sides and nine feet high, containing 1,440 cubic feet of air, twenty-two per cent, of carbonic acid gas, which, continued for twenty-four hours without ventilation, would reach the fatal four per cent. Prof.
To what conditions are the injurious effects of keeping animals in a poorly ventilated stable due? State the purpose of ventilation. How can the need of ventilation be determined in a stable? State the causes of "cold" in the head; give the treatment. State the cause of bronchitis; give the treatment. What are the causes of pneumonia? Describe the symptoms and treatment.
The proper ventilation of a house and its surroundings should form as prominent a consideration in the plans of builders and architects as do the grading of the land, the size of the rooms, and the cost of heating. The object of ventilation is twofold: First, to provide for the removal of the impure air; second, for a supply of pure air.
No draught could come from the window, for the window was not 'made to open. The age of ventilation had not arrived. Sophia shut the other two doors. And, each near a door, the girls gazed at Mr. Povey behind his back, irresolute, but filled with a delicious sense of responsibility. The situation was on a different plane now. The seriousness of Mr.
Not a soul in the gardens. Then he felt a draught on the crown of his head, and looking aloft he saw that the summit of the window had a transverse glazed flap, for ventilation, and that this flap had been left open. If he could have climbed up, he might have fallen out on the other side into the gardens and liberty. But the summit of the window was at least sixteen feet from the floor.
Deep breathing is undoubtedly extremely beneficial. Most of us, due largely to the fact that Nature leaves a considerable margin of safety, are able to carry on our ordinary activities without the requisite ventilation of the lungs, especially if we do not exercise. This, however, is injurious to the lungs, for it allows the blood to stagnate in them.
With this equipment and a good supply of heat, any room can be properly ventilated and kept so. But it will not ventilate itself. Ventilation, like the colors of the great painter Turner, must be "mixed with brains"; and those brains must be in the room itself, not down in the basement.
