\.Ej"pn-iiiiriit* on Nerve Crossing. 



The experiments on nerve crossing were undertaken in order to 

 ascertain whether, after division and cross union of the entire nerve 

 supply of two antagonistic groups of muscles, the animal can regain 

 the power of performing voluntary co-ordinated movements with the 

 affected muscles, and also to ascertain the effects on the cerebral cor- 

 tical centres affected by the crossing. 



The object of this was to ascertain if the organism has the power to 

 compensate for a change whereby nerve centres are brought -into 

 connection with peripheral endings, not by nature belonging to them. 



The experiments were made on the right fore-limb of dogs, and
