311. MUSCLES ARE INCLUDED among the organs of 

 sense, and are the only organs that require to be con- 

 nected with the mind by two kinds of nerves. 



312. Inf. SENSATION AND MOTION are the only 

 functions needed by the mind, not only for superintend- 

 ing all the operations in the body, but all its relations 

 to the external world. 



313. Inf. This is another exhibition of the man- 

 ner in which beauty, simplicity, and completeness are 

 exhibited in the construction of the human body. 



SECTION III. 

 Emotory Organs. 



314. EMOTIONS are functions, for producing which 

 the mind requires the activity of Ganglia only. 



315. THAT EMOTIONS RESULT FROM THE ACTIVITY OF 

 THE GANGLIA is proved by the effects of ether, laughing 

 gas, tickling, and other physical causes that excite emo- 

 tions, despite the will of the mind that they shall not. 



316. How THE MIND AND EMOTORY GANGLIA act 

 upon each other, or how they should be classed, is a 

 profound mystery, the solution of which, it is hoped, 

 will be made ere long, and immortalize the discoverer. 



317. THE EMOTORY GANGLIA ARE ALSO RELATED to 

 the Sensatory on the one hand, and to the Motor y on 

 the other, through which they are constantly manifest- 

 ing their activities, as illustrated in the following tables, 

 in which the arrows indicate the direction in which the 

 influence is exerted : the Mind acting on and being acted 

 on by the Emotory Ganglia, is connected by two arrows :
