1 16 THE COMMON FROG. [chap. 



Mr. G. H. Lewes has long contended against the 

 attribution of sensation to the brain exclusively, and 

 Dr. Bastian has recently supported and enforced 

 similar views. 



The latter remarks in his "Beginnings of Life/'* — ■

The brain of the frog consists of the same essential 

 parts as does the brain of all the vertebrate animals, 

 including man. In the form and in the proportions 

 of those parts, however, it differs extremely from the 

 higher animals (and above all from man), and resem- 

 bles the lower forms — the brain of the frog (and of 

 Batrachians generally) offering a much closer resem- 

 blance to that of a lizard than to that of a mammal. 



The brain of man consists of the following funda- 

 mental parts : 



I. A pair (one on each side) of small rounded 

 bodies, each connected, by a long stalk, with the 

 mass of the brain, and each shaped somewhat like a 

 life-preserver. These are the ''olfactory lobes," and
