Diagram of a cell. The lower segment illustrates the fibrillar theory, the 

 upper the granular theory, the left the foam theory. At the right the proto- 

 plasmic threads radiate from the centrosome. The nuclear network consists 

 of nuclein, linin, and lantanin. (Symonowicz.) 



THE CELL 



The cell, protoplasm or bioplasm is the anatomic 

 and physiologic bases of the body. All growth, repair, 

 disintegration, heat, energy, and life of the tissues 

 (whether normal or abnormal) depend upon the histo- 

 logic cell as a unit to work upon. Cells are seen only
