Ch. Eonget, and, more recently, Navalichin and 

 Kytmanoff. 



That is to say, the nerve-stems (fig. 23, 6), accord- 

 ing to these authors, would not terminate as those 

 represented by the said figure, which are inter- 

 cellular, but, when once placed between cell and 

 cell, the dichotomy of the nerve-fillets would con- 

 tinue passing them into the very interior of the 

 cell, in order to place itself in connection with the 

 protoplasm and nucleus ; there would be con- 

 sequently consubstantiality between the nervous 

 and glandular elements. 



To a certain extent we should conclude that in 

 the superior animals there exists inside their 

 tissues the same consubstantiality as is found in the 

 organic kingdom in the inferior animals, the con- 

 substantiality of which we have spoken between 

 the sensitive element and the motor in the actiniarii 

 (see p. 42, fig. 2). This gives a clear idea of the 

 unity and solidarity of the different systems in one 

 and the same organism. 



In the case before us it will suffice to refer to the 

 state of the matter as represented in fig. 23, upon 

 which there is a consensus of opinion, waiting until 

 the progress of technical knowledge confirms 

 beyond dispute the termination of the nerve-fillets 

 in the interior of the cells.
