Seen from above, however, the epithelial cells are found to be polygonal, and each containing a round nucleus. In the terminal period of secretion the cells may be found to have greatly increased in size, possess one to three nuclei, and contain in the portions directed toward the alveoli large numbers of fat-globules. Often the cells may be seen to undergo subdivision, a part falling free into the alveolus (Figs. 262, 263, and 264). Between these two extreme periods.
