NERVOUS SYSTEM. 



Under the head of Sensorial Function, page 156, we 

 have given a general account of the brain and nerves, 

 and have illustrated the several senses of touch, taste, 

 smell, hearing, and seeing, by figures and explanations. 

 At page 204 is a figure of the brain of man, with ref- 

 erences to its several parts, and the necessary explana- 

 tions ; and at page 223, under the head of " Connection 

 between the Nervous and Muscular Systems," it is sta- 

 ted that the muscles are furnished with two sets of 

 nerves, one set for motion, and the other for sensation. 

 We here propose to give more minute details of the 

 Physiology and Anatomy of the nervous system in man, 

 illustrated by a figure showing the distribution of the 

 nervous trunks, in the several parts of the body.
