His jaws are working as a mill--and a verycomplex mill too--grinding the corn, or crushing the grass to a pulp. Assoon as that operation has taken place, the food is passed down tothe stomach, and there it is mixed with the chemical fluid called thegastric juice, a substance which has the peculiar property of makingsoluble and dissolving out the nutritious matter in the grass, andleaving behind those parts which are not nutritious; so that you have, first, the mill, then a sort of chemical dige...ster; and then the food, thus partially dissolved, is carried back by the muscular contractionsof the intestines into the hinder parts of the body, while the solubleportions are taken up into the blood. The blood is contained in a vastsystem of pipes, spreading through the whole body, connected with aforce pump, --the heart, --which, by its position and by the contractionsof its valves, keeps the blood constantly circulating in one direction, never allowing it to rest; and then, by means of this circulation ofthe blood, laden as it is with the products of digestion, the skin, theflesh, the hair, and every other part of the body, draws from it thatwhich it wants, and every one of these organs derives those materialswhich are necessary to enable it to do its work.
