 glossal nerves. 



Bechterew has classified the fibres of the spinal Bech- 

 cord and medulla oblongata connected with the ciassifioa- 

 cerebellum according to the direction in which it is 

 supposed that the impulses travel. As centripetal he 

 regards the posterior column, the direct cerebellar 

 tract, the cerebellar olive tract, and the ascending 

 antero-lateral tract ; as centrifugal he designates the 

 cerebellar, superior olive tract, the fasciculus longi- 

 tudinalis dorsalis, the fasciculus antero-marginalis, 

 the fasciculus intermedins, and a part of the cerebellar 

 olive fibres. 



It will be seen from the evidence already set forth 



that the cerebellum is connected either directly or 



indirectly with every part of the nervous system, and 



that it is thus most favourably placed to act as a 



general reinforcing centre for nutritive and functional 



purposes. 



It has been related how, with respect to one of the Brief sum-

that cause. We have considered the cases of two 



girls, the one totally lacking a cerebellum the other 



with but a rudimentary fragment, both of whom 



showed many signs of weakness, and succumbed to an 



early death. We have numerous instances of removal
