 are not merely for the purpose of serving as the channel for the 

 impulses of muscular sense, but are the means by which the cere- 

 bellum transforms or elaborates sensory impulses, not of muscular 

 sense alone or chiefly, but probably of all kinds, in order that 

 they may take part in cerebral operations, of which the coor- 

 dination of bodily movements may be one, but probably is only 

 one of several or even of many.
