OF THE SPINAL CORD 149 



abolishes the pain and temperature senses while 

 tactile sense escapes. There will probably be spastic 

 paraplegia as well. 



It will not be necessary to refer here to the diagnosis 

 of the later complications, such as myelitis and the 

 various neuroses. 



Unfortunately the central nervous system is so 

 highly specialized that it has lost the power of 

 regeneration after injury, not only in man (unless we 

 accept the evidence of the famous Stewart-Harte 

 case !) but also in nearly all animals. The newt, it 

 is true, can form a new cord if its tail is lopped off, 

 but the newt has marvellous powers of regeneration, 

 and can even grow a new lens if the front of its eye 

 is removed !
