ratus. The heart, the lungs, the stomach, the Hver, tho 

 kidneys, are much ahke in all. The same fluid — for no dis- 

 tinction of blood has been observed — circulates through their 

 vessels, and nearly in the same order. The same cause, 

 therefore, whatever that cause was, has been concerned in 

 the origin, has governed the production of these diflerent 

 animal forms. 



When we pass on to smaller animals, or to the inhabi- 

 tants 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 attend- 

 ed, through all its varieties and deflections, by subserviences 

 to special occasions and utilities. 



1. The covering of different animals — though whether 

 I am correct in classing this under their anatomy, I do not 

 know — is the first thing which presents itself to our obser- 

 vation ; and is, in truth, both for its variety and its suitable- 

 ness to their several natures, as much to be admired as any 

 part of their structure. "We have bristles, hair, wool, furs, 

 feathers, quills, prickles, scales ; yet in this diversity both ol 

 material and form, we cannot change one animal's coat for 

 another without evidently changing it for the worse ; taking 

 care, however, to remark, that these coverings are, in many 

 cases, armor as well as clothing ; intended for protection 

 as well as warmth. 



The human animal is the only one which is naked, and 

 the only one which can clothe itself This is one of the 

 properties which renders him an animal of all climates, and 

 of all seasons. He can adapt the warmth or lightness ol 

 his covering to the temperature of his habitation. Had he 

 been born with a fleece upon his back, although he might 

 have been comforted by its warmth in high latitudes, it 

 would have oppressed him by its weight and heat, as the 

 species spread towards the equator. 



What art, however, does for men. nature has, in man)
