MENTAL AND CORPOREAL. 295 



Among the most important of these may be 

 mentioned mathematics ; which teach him to 

 calculate numbers, quantities, magnitudes, and 

 distances, with an accuracy never to be ques- 

 tioned, and irresistibly impress on his mind, 

 that in all investigations, the emanation of truth 

 is to be his primary object, and that this can 

 only be accomplished by a judicious arrange- 

 ment of his ideas, the closest application to the 

 subject, and a just comparison of things as they 

 present themselves to his notice. 



Thus by a knowledge of this interesting science, 

 numerical questions have been answered, pro- 

 blems solved, and calculations made, that with- 

 out it, never could have been accomplished. 

 While not only the dimensions of the globe and 

 of its several parts have been accurately ascer- 

 tained ; but (as we have before hinted,) the laws 

 of space, magnitude, and quantity, as well sepa- 

 rately as relatively, have been laid down with a 

 precision, that, independently of their practical 

 importance, bespeak an advance of intellect, and 

 a degree of industry, most truly astonishing. 



With mathematics as a basis, man is also pre- 

 pared to enter upon these sciences, which practi- 

 cally explain the laws by which each proportion 

 of the universe is regulated ; and thus to descend 

 to the minutiae of things, which, before, he had 

 only viewed in the outline. 



Thus by the science of astronomy, he is enabled 

 with wonderful accuracy, to determine the situ-
