ITS ANALOGIES WITH THE NERVOUS SYSTEM. 407 



elaborated and more heterogeneous, and have eventually 

 added to them a new element facilitating the nutritive pro 

 cesses. The channels of communication pass through similar 

 phases of development, which bring them to analogous 

 forms. And the directions, rhythms, and rates of cir 

 culation, progress by like steps to like final conditions. 



We come at length to the nervous system. Having no 

 ticed the primary differentiation of societies into the gov 

 erning and governed classes, and observed its analogy to 

 the differentiation of the two primary tissues which respec 

 tively developc into organs of external action and organs 

 of alimentation ; having noticed some of the leading anal 

 ogies between the development of industrial arrangements 

 and that of the alimentary apparatus ; and having, above, 

 more fully traced the analogies between the distributing 

 systems, social and individual ; we have now to compare 

 the appliances by which a society, as a whole, is regulated, 

 with those by Avhich th*e movements of an individual crea 

 ture are regulated. We shall find here, parallelisms equally 

 striking with those already detailed. 



The class out of which governmental organization ori 

 ginates, is, as we have said, analogous in its relations to the 

 ectoderm of the lowest animals and of embryonic forms. 

 And as this primitive membrane, out of which the nervo- 

 muscular system is evolved, must, even in the first stage of 

 its differentiation, be slightly distinguished from the rest 

 by that greater impressibility and contractility characteriz 

 ing the organs to which it gives rise ; so, in that superior 

 class which is eventually transformed into the directo-exe- 

 cutivc system of a society (its legislative and defensive ap 

 pliances), does there exist in the beginning, a larger en 

 dowment of the capacities required for these higher social 

 functions. Always, in rude assemblages of men, the strong 

 est, most courageous, and most sagacious, become rulera
