SYSTEMATIC ANALYSIS OF GROUPS OR MECHANISMS. 



APPARATUS. 



SECTION I. 

 Mentory Apparatus. 



125. To DEVELOP THE MlND, TO MAKE BLOOD, 



AND TO CIRCULATE IT, several distinct operations, called 

 functions, must be performed. It is one operation or 

 function for the mind to receive an influence, and another 

 for it to exert one. To take air and to take food for 

 making blood are distinct functions. 



126. EACH FUNCTION REQUIRES an Apparatus, which 

 is the collective name of the parts that successively, or 

 combined, perform a function. 



127. THE NUMBER OF APPARATUSES into which each 

 mechanism can be divided will depend upon the number 

 of operations or functions required for the development 

 of the Mind, the making of blood and the circulation 

 of It. 



128. THE OPERATIONS OF THE MIND may be in- 

 cluded under four classes, Sensational, Emotional, Intel- 

 lectional, and Motional; that is, by which it experiences 

 Sensations, as of sight, hearing, warmth, hunger, pain, 

 health, &c. ; Emotions, as of joy, grief, anger, &c. ; In- 

 tellections, as thoughts, &c. ; and the power of producing 

 Motion. (See Ap. I.)
