12 INTRODUCTORY REMARKS. 



By classification according to uses, it will be perceived and 

 appreciated that the body is a unit, constructed of correlative 

 and subordinate parts, but all having a unitary purpose ; that, 

 commencing with man, composed of mind and body, we can de- 

 scend, by a regular gradation of subdependent relations, through 

 Members, Groups, Apparatuses, Organs, Textures, and Tissues, 

 (with the addition of fluids,) to the primary elements constitu- 

 ting the substratum of all parts, from which, by synthesis, the 

 steps can be retraced till we find every subordinate part culmi- 

 nate through its superior, in being a servant to the mind, for 

 the use and development of which the body is designed the 

 mind and body acting and reacting on each other in every cir- 

 cumstance in life. (See the Chart of Analysis and Synthesis, in 

 Appendix.) 



It must be evident that, by the use of this natural and legiti- 

 mate classification according to use, the labor of acquisition, 

 retention, and application, will be in a very noteworthy degree 

 abridged. 



This naturally leads to the third idea, which is, that a general 

 and brief analysis of the uses and construction of the body 

 should be given as an introduction to the synthetical study of 

 details, as then the necessity for them and their uses will be 

 more readily apprehended, since they are useful and necessary 

 only as they are subordinate to the great purpose for which the 

 body exists ; and their value will be more appreciated, and they 

 will become more interesting, as their relations to those purposes 

 are more clearly perceived. It may be added that the different 

 parts of the body are so intimately associated with, and act and 

 react so constantly on, each other, that a general knowledge of 

 all is necessary to the complete understanding of any one. 



If, however, any teacher thinks that details should be studied 

 first, he can adopt this plan by commencing with the synthetic 

 view. And in many instances it will be best for him to do this, 

 and conclude with the General Analysis, or he may have the
