It has been shown that farm animals, under ordinary stable conditions, cannot decrease the oxygen or increase the carbon dioxid content of the air to an extent dangerous to life. Even when the oxygen content of the air was reduced from about 21 per cent, to as low as 5 per cent., and the carbon dioxid raised to per cent., no appreciable detrimental effect was noticeabl

Fig. 38.âVentilating flues when cows face in. Similar results have been obtained when human beings were con- fined in an unventilated room. The reason why persons and animals get on so well in houses and stables with apparently no ventilation is that air is constantly entering and leaving through the cracks, crevices, and pores in the walls. â > The qualities that determine whether air is good or bad are: temperature, humidity, odor, and motion. The oxygen and carbonic acid gas content are of minor consideration; therefore, Digitized by Microsoft®.
