FIG. PAGE. 



76. A resting polymorphonuclear leucocyte. Its granules are stained 



but not its nucleus. The cell was alive 253 



77. A basophile leucocyte in the act of cell-division. The granules 



of the cell are in the centre. The lobes of the nucleus are at the 

 poles of the cell which is dividing into three 253 



78. An eosinophile leucocyte in the earliest stage of division. The 



granules were arranged in lines radiating outwards from the 

 centre of the cell. The lobes of the nucleus were at the poles . . 259 



79. Early stage of division of a neutrophile leucocyte 259 



80. A dividing leucocyte 261 



81. A dividing leucocyte 261 



8lA. Division of a leucocyte. The linear arrangement of the granules 



could be well seen 263 



82. A dividing leucocyte . 263 



83. A dividing leucocyte 265 



84. A dividing leucocyte 265 



85. A dividing leucocyte 267 



86. A dividing leucocyte 267 



87. An eosinophile leucocyte with its granules stained . 275 



88. A field containing a neutrophile, an eosinophile, and a basophile 



leucocyte. The upper cell is the neutrophile and the lower one 

 the basophile cell. All the cells are ruptured, but their granules 

 are stained 279 



89. A basophile leucocyte whose stained granules have been turned 



black by heat 279 



90. One of the negatives of a ruptured eosinophile leucocyte (negative 



No. 52) 285 



91. One of the negatives of a ruptured eosinophile leucocyte (negative 



No. 54) 285 



92. Counting the granules. The image of the ruptured cell depicted 



on negative No. 52 is projected on to a sheet of white paper 

 pinned on to a screen 287 



93. Counting the granules of negative No. 54 287 



94. A dividing red cell from a cancer patient 295 



95. A dividing red cell from a cancer patient. The granules seem to 



be arranged in an indefinite figure 295 



96. Very early stage of mitosis in a lymphocyte induced by decom- 



posed extract of suprarenal gland. No stain 301 



97. Mitosis of a lymphocyte induced by decomposed suprarenal 



extract. No stain 301 



98. Mitosis induced in a lymphocyte by decomposed extract. No 



stain 303 



99. Asymmetrical division induced by decomposed extract. No 



stain or atropine is present 303 



100. Mitosis induced by fresh extract of suprarenal gland. No stain 



or augmentor present 307
