NATURAL THEOLOGY. 221 



refuse any longer our assent to the proposition — 

 "that intelligence, properly and strictly so called, 

 (including, under that name, foresight, considera- 

 tion, reference to utility,) had been employed, as 

 well in the primitive plan, as in the several changes 

 and accommodations which it is made to un- 

 dergo." 



Very much of this reasoning is applicable to 

 what has been called Comparative Anatomy. In 

 their general economy, in the outlines of the plan, 

 in the construction as well as offices of their prin- 

 cipal parts, there exists between all large terres- 

 trial animals a close resemblance. In all, life is 

 sustained, and the body nourished, by nearly the 

 same apparatus. The heart, the lungs, the stomach, 

 the liver, the kidneys, are much alike in all. The 

 same fluid (for no distinction of blood has been 

 observed,) circulates through their vessels, and 

 nearly in the same order. The same cause, there- 

 fore, whatever that cause was, has been concern- 

 ed in the origin, has governed the production, of 

 these different animal forms. 



When we pass on to smaller animals, or to the 

 inhabitants of a different element, the resemblance 

 becomes more distant and more obscure ; but still 

 the plan accompanies us. 



And, what we can never enough commend, and 

 which it is our business at present to exemplify, 

 the plan is attended, through all its varieties and 

 deflections, by subserviences to special occasions 

 and utilities.
