Read at Canterbury, Feb. 8th, 1892. 



The Lecturer said that his aim was to show, how in the ordinary 

 course of our life, our business, our Government, even our schoolboys' 

 games, a process is going on which is in its essence, the same as that on 

 which the long and majestic course of creation has proceeded. 



By the simple illustration of a large business as the growth and 

 development from a small beginning, he illustrated the change from 

 what is simple to what is complex, from what is uniform to what is 

 different in its parts, from Avhat is homogeneous, or alike in pattern 

 throughout, to what is heterogeneous, it involves in fact, differentiation 

 and specialization of function. These two phrases, differentiation and 

 specialization of function, were to be the key to his subject.
