It is the purpose of this book to serve as a short introduction to the 

 comparative physiology of the brain and of the central nervous system. 

 Physiology has thus far been essentially the physiology of vertebrates. The 

 author is convinced, however, that for the establishment of the laws of life- 

 phenomena a broader basis is necessary, and that such a basis can be furnished 

 only by a comparative physiology which includes all classes of the animal 

 kingdom. His experience indicates that the transition from the old to the 

 comparative physiology can be most readily accomplished through the physio- 

 logy of the central nervous system.
