But it will be clear, from the facts of the case, that many nerves, both afferent and efferent, are concerned; and it is more than likely that our explanations of the (^ntire process are quite inadequate to unravel its real complexity.

It is important to reinember that the intestinal mucous membrane is supplied not only with secreting glands but lym- phatic tissue, in the form of the solitary and agminated glands (Peyer's patches) and thickly studded with villi, giving the I'mall gut that velvety appearance appreciable even by the naked eye.
