ON BIOGENESIS 57 



united protoplasmic mass with vital energy, the re- 

 arrangement of its molecular elements, in virtue of that 

 endowment, into living and developing structures with 

 functional attributes conformable to the living necessities, 

 in whole and in part, of such an organism, and the 

 concurrent preparation, for its subsequent perpetuation, 

 of a potentially endowed and organised residual biogenic 

 plasm, which will, in turn, contribute to or ensure a 

 further biogenic combination and sequence, to be repeated 

 ad infinitum, or until the resultant multi-cellular organism 

 requires the division of its texture into specially endowed 

 cell groups, or nascent organs. 



In the process of multi-cellular increase, and the 

 differentiation of the uni-cellular organism, the unity, 

 material and dynamic, of that organism is secured and 

 maintained by the collateral uniting or inter-cell pro- 

 cesses, left by kariokinesis during and after cell 

 division and detachment, these processes constituting the 

 foundation of the sympathetic nervous system, which 

 ultimately unites into one multi-cell community every 

 division and subdivision of the original uni-cellular 

 organism, and, therefore, operates and administrates that 

 cell community on the lines foreshadowed in the mole- 

 cularly determined innervation of that, the uni-cellular 

 organism. All vegetable, and the greater part of the 

 lower animal, forms, are so innervated and vitally 

 operated, the vital energy, or life, being transmitted and 

 maintained by somatic, material, and dynamic agencies, 

 entirely under the control of a central or original, and 

 the derived sympathetic nervature, molecular, stranded, 

 or fibrillar, with, in the most advanced forms, the 

 provision of ganglionic centres, for specific structural 

 purposes and local functional contingencies. 



The biogenic phenomena, here described, constitute 

 exactly those observable in the first stages of human 

 biogenetic development, as well as those observable in 

 the first stages of development of all systemically inner- 

 vated animals, and are alone absolutely sufficient to 

 meet the organic requirements, material and dynamic, of 

 the vegetable kingdom, and the larger half of the animal 

 kingdom the other half of the animal kingdom calling
