ABSORPTION FROM THE DIGESTIVE CAVITY. 181 to this investigator,* the villi (c, Figs. 80 and 81, a, Fig. 82) are investedby a single layer of columnar cells, with a broad free, and a narrower attachedextremity. The free extremity presents a thickened, bright, and highlyrefractile border surrounding the open mouth of the cell. The border variesin thickness and breadth in different cells, even of the same villus; and whenthe cells are examined from above, their margins seem to be continuous witheach other, so that a kind of mosaic is formed. Immediately internal to theborder (or perhaps projecting from the whole of the free surface of the cells) Fig. 80. Fie. 81. Fig. 82.
