 presently, is principally psychic in its main elements,

 the mind of the world will be engaged for long into 

 the future. 



Now the immense potentiality of this collective 

 heredity as the cause of efficiency in civilization 

 is due to two things, one of which carries us con- 

 siderably beyond the extended horizon of Sir Edwin 

 Ray Lankester's striking outlook. It is due, in the 

 first place, to that accumulation of recorded know-
