From such views we dissent. We believe they are opposed to what we know of living tissue everywhere, and are not sup- ported by the special facts of digestion. When certain foreign bodies (as purgatives) are introduced into the blood or the ali- mentary ranal, that diffusiion takes place, according to physical laws, may indicate the manner in which the intestine can act; but even admitting that under such circumstances physical principles actually do explain the whole, which we do not grant, it would by no means follow that such was the natural behav- ior of this organ in the disoharge of its ordinary Please note that these images are extracted from scanned page images that may have bee
