Food and air are the two means by which bodies live. In the full-grown man, whose weight will average about one hundred and fifty-four pounds, one hundred and eleven pounds is oxygen drawn from the air we breathe. Only when food has been dissolved in the stomach, absorbed at last into the blood, and by means of circulation brought into contact with the oxygen of the air taken into our lungs, can it begin to really feed and nourish the body; so that the lungs may, after all, be regarded as the true stomach, the other being not much more than the food-receptacle.
