14 WARFARE IN THE HUMAN BODY 



posed of chemical substances, which are determinants of 

 future morphogenesis. Such a view is in keeping with 

 Darwin's pangenes, and does not contradict Hartog's 

 physical mito-kinetic interpretation of the mitotic cell- 

 fields. 



If, then, by following the suggestions of chemistry and 

 physiology, rather than by relying purely on limited experi- 

 ment and the microscope, we finally rid biology of the view 

 that there is true nucleo-plasm, and proceed on the assump- 

 tion that the nucleus is a varying vacuole, or " tool-shop," 

 and food store-house in which catalysts, or determinants, 

 or activators, are kept, and from which they may be drawn 

 by various physical causes, use is being made of at least 

 three sciences, or four if we include physics, and we seem 

 on a path likely to lead to result. At least we shall not 

 ignore the environment, since it is, and must be, the field 

 from which all morphogenetic materials were originally 

 drawn, however complex they appear when used, com- 

 bined, and specialized by special organs, themselves the 

 earlier results of similar catalysts working in the embryo. 



Yet another science may be used to help towards a 

 possible demonstration. An illustration is not a proof, 

 but, as suggested before, when it contains a larger number 

 of points of likeness it ceases to be a mere illustration. 

 The observed phenomena then seem peculiarly related to 

 each other, and if the illustration deals with familiar 

 phenomena the previously inexplicable problem may have 

 an intense light thrown upon it. It was such considerations, 

 combined with the scientific postulate that all biologic 

 phenomena, on whatever plane of development, follow the 

 same laws, which led me to seek in sociology and social 

 life some real illustrations of budding and mitosis, being 

 convinced that if found, they would be of a similar nature.
