INTRODUCTION. 
Tue subject of this research was suggested to me by Dr. 
Gustav Mann, with the view of throwing some further light 
upon the functions of the nucleus and nucleolus, and to test 
whether his views were correct,—namely, that the chromatin 
segments are organs for the elaboration of food; that the 
nuclear chromatin is not the essential element, inasmuch as 
it only represents partly elaborated material; that the nu- 
cleolus is a storehouse for some elaborated matter, &c.1 By 
1 Gustav Mann, “ The Functions, Staining Reactions, and Structure of 
Nuclei,” ‘ Proc. British Association,’ Section D, 1892, Edinburgh meeting.
