1 cannot understand what present phy- 

 siologists mean, when they speak of cir- 

 .cumstances in the animal economy of man 

 being the result of his possessing larger 

 organs for the developement of nervous 

 energy. Do they mean to insinuate that 

 the nervous energy is different from vitai 

 energy in general ? Or, that the organiza- 

 tion of the brain and nerves is necessary 

 for the preparation of vital energy ? Both 

 propositions are unreasonable, and the lat- 

 ter contradicted by our knowing that the 

 lower kinds of living beings, which have 

 neither brain nor nerves, possess vitality 

 in the most energetic and permanent de- 

 gree. Neither do I understand what they 

 mean by attributing sensation to those parts 

 where it is supposed to take place.
