 and intelligence of youth ; the hilarity and sport- 

 iveness of childhood, arrd the quiet unconsciousness 

 of infancy. The body shrivels, and its outlines 

 become angular ; the teeth fall out ; the eyes are 

 dim ; and the hearing, touch, and taste, imperfect. 

 We reach the verge of life ; and, after tottering for 

 a while upon the brink of the grave, we die, and 

 the place which knew us knows us no more. 



Questions. 



Can an infant direct its eyes and carry its hand to its 

 mouth 1 



In what state are its bones 1 



How does it pass the greatest part of its time ? 



Can you mention how we are changed in some respects in 

 childhood ? 



What do we learn at this period of our lives 1 T 4 >; 



When do our bones become hard, and our muscles capable 

 of great exertion ? 



Are our minds active and inquisitive in youth ? 



What should we be careful to do at this time 1 



When are our bodies full grown 1 



Are our complexion and voice changed in manhood 1 



Why is it that we no longer delight, as we used to do, in 

 bodily exercises 1 



What happens to us when we become old 1
