as in reference to the hypothetical man " created in the 

 full maturity of his faculties." 



An endowment like Articulate Speech, when once 

 started whether by some hidden and unknown process 

 of natural development, or as a still more occult God- 

 sent gift to Man was by its very nature almost certain 

 to have led its possessors by degrees along an upward 

 path of cerebral development. How slow and tardy the 

 process has been we are now beginning dimly to perceive, 

 by reason of those researches which have made known to 

 us the great antiquity of the Human Eace and the far 

 remote period of Man's appearance upon this Earth. 



Anterior to historical epochs, the Men who were the 

 contemporaries of the great Mammoths, whose remains 

 are found in the Post-Tertiary Drift, those of the Bone- 

 Caves, those of the Shell-heaps and the Peat-bogs, as 

 well as those of the Cromlech period and the Early Lake- 

 dwelliogs, lived for untold ages in a state of simplicity 

 and barbarism far greater than that which still continues 

 among many of the savage and semi- savage races covering 

 so large a proportion of the Earth's surface. 



Progress, in the early stages of human history, was 

 necessarily so slow as to have seemed almost absent, even 

 if we mark time by centuries. Gradually, however, as a 

 nomad life gave place to a more complex communal life, 

 the advantages of co-operation would show themselves in 

 many ways. The commencement of a developing Social 

 Organization necessarily entails a greater diversity in 

 the relations of man with man, which would naturally 

 become reflected in their Language, and proportionately 

 increase the area of their thought-processes, by giving 

 birth to new exercises, or, at all events, by greatly strength- 

 ening certain previously embryonic mental processes.
