AND THE LIVING PRINCIPLE.

living principle which determines that structure. 

 What we have contemplated is the fact, that by 

 the structure of these organs, actuated by a living 

 principle, certain functions are performed, which, 

 without such structure, or such living energy, nei- 

 ther the one nor the other alone, could have 

 accomplished. The structure is the organiza- 

 tion; the living principle is something else. 

 They are intimately connected together, no doubt ; 

 but so is the mind with the body. The one 

 is the substance moved ; the other the moving 

 power. Holding, then, organization to refer to the 

 structure of the organs, we may perceive, that, 

 though more complex and delicate in its arrange- 

 ments than crystallization, it maybe equally resolved 

 into a principle or law, impressed on matter, for the 

 application of mechanical power, and the evolution 

 of chemical affinities. 



There is one point of view, however, in which 

 crystals and organized bodies materially differ. 

 The original specific character of each animal 

 and vegetable, in the thousand and ten thou- 

 sand varieties that overspread the earth, is no ef- 

 fect of chemical affinity. The peculiar character 

 of each of these, could only be impressed by that 

 Great Being, who, when he commanded the world 

 into existence, willed, that the tribes of the animal 

 and vegetable kingdoms, should each be brought 

 forth after their kind. The parent, therefore, in 

 each of these, in reproducing the species, has not to
