assigniizig to the cereT^ellum tlie office of douTbly-compourd 

 coordination in space, and to the cerebrum the office of 

 doubly-compound coordination in time. The facts of com- 

 parative anatomy, and of comparative psychology, so far as 

 Vnown, are in harmony with this opinion. We saw in the 

 chapter on Life and Mind that the extension of the cor- 

 resnondence in time at first goes on parallel with the exten- 

 dion of the correspondence in space ; the increased area over 

 which the organism can act being the measure of its in- 

 creased capacity for adapting its actions to longer and longer 

 sequences in the environment. But we saw also that in the 

 human race the extension of the correspondence in time has 

 gone on far more rapidly than the extension in space; the 

 most striking characteristic of intellectual progress being the 

 ability of civilized man to adapt his inferences and actions 

 to remote contingencies. Side by side with these facts, 

 comparative anatomy shows us that the cerebrum and cere- 

 bellum at first keep pace with each other in growth ; but, 

 as we reach those higher mammals which exhibit some 

 degree of foresight, we find the cerebrum outgrowing the 

 cerebellum and overlapping it ; while in man the growth of 

 the cerebrum has been so great as to render comparatively 

 insignificant all other changes in the nervous system. With 

 the enormous cerebrum of civilized man we may further 

 contrast the preponderant cerebellum in those carnivoroup 

 birds whose psychical life consists chiefly in the coordination 

 of those extremely complex and remote space-relations in- 

 volved in the swooping upon prey from great distances. 

 The human cerebellum is absolutely larger than that of such 

 birds ; but its smallness relatively to the cerebrum is a fact 

 parallel with the simplicity of the space-relations which 

 man coordinates, as compared with the time-relations. 

 Among the latter are comprised all our ideas of cause, 

 motion, progress, — in a word, all manifestations of force 

 which involve the relation of sequence. But these ideas
