Chapter XXXI.—The Intestines.

“What reason also is employed in the intestines, which are arranged in long circular windings, that they may gradually carry off the refuse of the food, so as neither to render places suddenly empty, and so as not to be hindered by the food that is taken afterwards!  But they are made like a membrane, that the parts that are outside of them may gradually receive moisture, which if it were poured out suddenly would empty the internal parts; and not hindered by a thick skin, which would render the outside dry, and disturb the whole fabric of man with distressing thirst.
