202 THE HUMAN BODY. 



a full grown native of the Azores, where the 

 people formerly exposed their dead in open places 

 to be dried by the sun, has been found weighing 

 not more than twelve pounds, though the bones 

 and other solids were quite perfect : yet this must 

 have weighed at least 120 Ibs. when living, or in 

 its natural state. 



Most of our organs are double. Thus we have 

 two eyes ; the nose is divided ; the tongue consists 

 of two parts ; the neck has a set of muscles and 

 vessels on each side ; we have two arms and 

 hands ; two legs and feet ; and the brain consists 

 of two divisions. These double parts are very 

 similar in their structure. 



Those organs by which we move from place to 

 place, and eat, drink, and perform manual labour, 

 and other actions, are under our own government 

 or will : that is, we can employ them or not, just 

 as we choose; hence they are named voluntary. 



Other organs, on the constant action of which 

 our very life depends, are not under our own 

 government. The heart, the lungs, the intes- 

 tines, and other parts, act, whether we are 

 waking or sleeping, whether we wish or not, and 

 on this account are called involuntary. Over 

 these our Divine Author has given us no power, 

 or our lives would be in continual danger, as 

 our passions and negligence might prove our 

 destruction. 



The whole body is covered with skin. This 

 serves as a protection to the delicate and sensitive
