the rest in economic respects. The next stage is 

 distinguished by a segregation of these social units 

 into a few distinct classes — ^warriors, priests, and 

 slaves. A further advance is seen in the sundering

 also perceive that this coalescence of like parts, as 

 seen in the concentration of particular manufactures 

 in particular districts, and this separation of agents 

 having separate functions, as seen in the more and 

 more minute division of labour, are still going on. 



" Thus do we find, not only that the analogy 

 between a society and a living creature is borne out 

 to a degree quite unsuspected by those who com-
