ITS ANALOGIES WITH THE NERVOUS SYSTEM. 407 



elaborated and more heterogeneous, and have eventually 

 added to them a new element flxcilitating 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 develope 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 which the 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 norvo- 

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

 its differentiation, be shghtly distingnished 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- 

 cutive 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- 

 sst, most courageous, and most sagacious, become rulers
