Fusiform fibres of fibro-plasfic tissue. 4. The narrow 

 and long fusiform cell, containing a nucleus (5) with a 

 small dot in its centre for a nucleolus. Average length 

 of cell, l-300th of an inch.

4. The concentric cancer-cell is formed of an ovoid or spherical 

 body, surrounded by concentric rings, increasing in size as they go 



further out. This variety

 cancerous tumor, and is 

 met with but rarely. (Fig.

authors, of their splitting up into smaller segments, and multiplying 

 by division. They are of variable form, and often contain three, 

 four, or more cancer-nuclei. (Figs. 84 and 64.) 



6. Agglomerated nuclei are also rarely met with, which seem to be 

 held together by the granular homogeneous substance in which 

 they are generated. They seem to have no cell-wall about them, 

 and may be recognized by the bulk of their envelop. (Fig. 85.)
