outlying part of the cerebellar tract, certainly continue uncrossed 

 into the peduncle of the same side. We may conclude, therefore, 

 that the ties of the cerebellum with the posterior roots are both 

 crossed and uncrossed. And we may regard this double grip of the 

 cerebellum on the cord, this grip on both sides of it, as an addi- 

 tional evidence that the ties of the cerebellum with the spinal cord 

 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.
