development of the albuminoid granules the chromatoid granules 

 of the nucleus, the protein of the cytoplasm, and the fat of the 

 vacuoles are all utilized, and merged into a form where the 

 different constituents are not only different from the former cell 

 constituents, but also can no longer be distinguished from each 

 other by staining reactions. The conclusion can be drawn, 

 however, that these albuminoid globules represent the cell element 

 in which the chemical transformations take place by which all 

 the cell constituents (except possibly the residual nucleus) 

 undergo chemical reorganization in preparation for tissue use. 



In the following section of this paper an interpretation of the 

 changes in structure and in staining reaction of the cell elements 

 will be undertaken. A bibliography there included will also 

 cover the first section.
