8 INTRODUCTORY REMARKS.

 every effect ; to perceive that design is essential to the best re- 

 sults ; to analyze and synthetize ; to classify and arrange sys- 

 tematically ; to induce and deduce in other words, to think 

 correctly. 



Life, to be most useful, should be full of executed purposes. 

 A true life may be called a great purpose compounded of many 

 subsidiary ones. Hence the mind is constituted, and should be

Now, in the Divine mind there was a purpose, to execute

 and exhibited by the properly arranged study of the human 

 system ? 



This study is also a constant hymn to the Deity. His own 

 works praise him silently and profoundly, impressing the mind 

 far beyond what can be done by any words of man, and render-

 manner, by adding to the number of its days, and by increasing 

 their efficiency, both mental and physical. In this view, the 

 effect of this study, universally and properly pursued, would be
