The laws and mechanics of circulation, with the principle involved in animal movement . erent stages of cell growth in the follow-ing cut (Fig. 103, a, b, c, d, e), beginning with the nuclei andprogressing till the cell is perfected {E) Accordingly, I haveventured to connect the columnar cells of the villi with thenerves proceeding from the ganglionic layer of Meissner(Fig. 107, 1) to the villi (2) This portion of the picture, there-fore, is ideal. But considering the energy in the absorptiveprocesses and the rapidity with which the cells expand, andespecially the quick response to stimulus I deemed myselfjustified in doing so. Not that a nerve fibre proceeds to eachindividual cell in the manner as given, for several may connectwith a nerve (Fig. 103, M), but that they promptly propagatesensory impressions produced by the food, for setting up the SERVES TO THE COLUMNAR EPITHELIUM. 269 reflex actions in the ganglia for producing the movements in themuscular cylinder, inclusive, of course, of the example, as soon as food is introduced into the stomach. Fig. 103.—A, B, C, D, E, isolated cylindrical cells with processes containing nuclei;A, B, D, E, magnified 590 diameters ; C, magnified 1,200 diameters; F, G, H,cylindrical cells with processes, which are evidently young cells, and form atffabeautiful mosaic. Magnified 1,100 diameters.—Pfluger.
