COSMIC PHILOSOPHY 



cular adjustments made in the trunk and limbs 

 are effected either directly by the spinal centres, 

 or indirectly by the sympathetic ganglia in co- 

 operation with the spinal centres. The medulla 

 coordinates all these muscular adjustments with 

 the muscular adjustments of the face, and with 

 the impressions received from the specialized 

 organs of sense. It' is therefore highly improb- 

 able that the supreme ganglia can be in any way 

 directly concerned with these coordinations. 

 And the improbability is increased by the fact 

 that the cerebrum and cerebellum are as desti- 

 tute of sensation as the free ends of the finger- 

 nails. Scratch one of the spinal centres, and 

 the result is tetanus. Scratch the medulla, and 

 the whole body is thrown into terrible convul- 

 sions. But the cerebrum and cerebellum may 

 be scratched and sliced without pain or convul- 

 sion. They take heed only of those impressions 

 which are communicated to them indirectly. 

 Countless multitudes of nerve fibres coming up 

 from the medulla are gathered together in the 

 corpora striata ; whence other fibres, continuing 

 from them, radiate to the innumerable cells of 

 which the supreme ganglia are composed. 



We must conclude, therefore, that the func- 

 tions of the cerebrum and cerebellum are com- 

 prised in the further compounding of the sen- 

 sory impressions already compounded in the 

 medulla. And as such compounding involves
