VENTILATION 65 unequal temperature, depending as they do on the air being heated by the bodies of animals occupying the building, are not only irregular but undesirable.

Artificial Ventilation.—If the air entering a building can be warmed and the place maintained at a temperature of 60° Fahr., the greatest op- ^^ ponent of fresh air can no longer have a valid reason left for closing an aperture. The maintenance of stables at a temperature of 60° Fahr. through the heat given off from the bodies of animals, as is at present the case, is hygienically bad. If it be considered neces- sary to bring up horses and cattle as tender hothouse plants, then to live at 60° in an air saturated with moisture is the best means of securing it. If it be recognised that this heated foul and moist atmosphere is unhealthy, and yet a tempera- ture of 60° is desired, it can only be obtained by artificial ventilation, the simplest system probably being that shown in A bracket containing a metal tube, bent m several direc- tions so as to give it a large surface, is placed opposite an inlet. Inside the tube is a Bunsen burner, the products of combustion being carried outside the stable. The heat travels through the whole length of the pipe,.
