COMPARATIVE ELECTRO-PHYSIOLOGY 



tissue, as between the abnormal and normal, through the 

 intermediate diphasic. 



From the various experiments, then, which have been 

 given in this chapter, it will be seen that the response of the 

 isolated vegetable nerve is in every respect similar to the 

 corresponding responses of animal nerve. And we shall also 

 see how, by means of the study of this vegetable nerve, we 

 are enabled to elucidate many obscurities in the responses 

 of the corresponding animal tissue. We shall in the next 

 chapter enter in detail into the question of the modifications 

 induced in the conductivity and excitability of vegetable 

 nerve under the action of various external agencies, and 

 these will be found to exhibit the strictest parallel with 

 corresponding variations Induced in the animal.
