The incoming air should not pass over, or through, any contaminating source, such as a manure pile, and it is very important that the general plan of construction should be well considered. Temperature and weight.—The second factor, difference in weight between the lighter warm and heavier cold air, is not so important in natural (windows and doors) as in artificial ventilation, and yet it is a factor of considerable importance. The heat which warms the air in the lower levels is that which comes from the bodies of the confined animals, as it is radiated from the surface or warmed in passing through the lungs. Diffusion of gages.—Carbonic gas is considerably heavier than air, but the lower air levels usually do not usually show much more C02 than the higher ones on account of diffusion, which takes place in response to the law of diffusion of gases—operat- ing independently of relative weights. This force is so strong.
