EXPLANATION OF FIGURES 



99 From an injection preparation. 



100 to 105 Flemming's fluid; iron-haematoxylin. 

 106 to 109 Bichromate-formalin; iron-haematoxylin. 



110 Sublimate-acetic acid; alum-haematoxylin. 



111 to 117 Meves' fluid, iron-haematoxylin. Figure 113 shows a cell which 

 is just undergoing constriction. The fragments are to some extent invaginated 

 the neighboring cells, which are not delineated in the figure. Figures 115 to 117, 

 constricted fragments which still contain nuclear fragments and zymogen 

 granules. 



118 Sublimate-acetic acid; alum-haematoxylin. Figures 114 and 118 show 

 normal cells containing constricted fragments. Some of the latter contain 

 nuclear portion, others none and appear homogeneous, and still others contain 

 zymogen granules.
