78 THE HOUSE I LIVE IN. 



There are four kinds of teeth in each jaw, 

 viz., four front teeth, two canine teeth, called 

 also eye teeth, four small grinders, and six 

 large grinders. Of these, half are of course 

 on each side. 



The fore teeth and eye teeth have but one 

 root each. The small grinders do not often 

 have more than one, but they are usually in- 

 dented lengthwise, so as to give the appearance 

 of two. The large grinders of the lower jaw 

 have two roots, and those of the upper have 

 three two before, and one behind, or on the 

 inside. 



Who does not admire a good set of teeth ? 

 With some people, they are one of the princi- 

 pal marks of beauty. But they are useful, as 

 well as handsome, as long as they remain 

 sound. The teeth of some persons remain 

 sound and beautiful all their days. Would you 

 like to have yours do so ? Let us then attend 

 to the following particular account of them ; 

 and perhaps when we know their nature and 

 structure better, we may better know how to 

 take care of them.
