EXPLANATION OF THE PLATES. 



PLATE I. 



VARIOUS FORMS OF CELLS. 



FIG. L* Blood of the adult. 1, Red globules, front view; 

 2, same in profile ; 3, same altered ; 4, white globule. 



FIG. II. Epithelial cells of the bladder. 1, Cell with 

 granular contents ; 2, its nucleus, also containing granules, one 

 of which (3) larger than the rest forms the nucleolus ; 4, cell 

 with two nuclei ; 5, group of cells retaining their original rela- 

 tion to each other. 



FIG. III. Hepatic cells. They are polygonal in shape, and 

 scattered amongst their granular contents free fat is to be seen 

 in the form of brilliant little pearl-like globules. 



FIG. IV. Epidermic cells. 1, Cells of the rete mucosum / 

 2, cells of the middle stratum ; 3, cells of the surface, in the 

 shape of granular scales without nuclei ; 4, other cells from the 

 superficial layer, detached and swelled by very dilute acid. 



FIG. V. Adipose cells from beneath the integument. Their 

 fluid contents are so transparent that the outlines of the. cells 

 alone are visible.
