120 THE HOUSE 1 LIVE IN. 



usually, though not always, arranged in pairs ; 

 that is, there is one on the right side of the 

 body exactly like one on the left side opposite 

 to it ; and so on. We cannot reckon the 

 whole number at less than four hundred and 

 fifty, and some make it above five hundred and 

 twenty. 



I have said that these muscles many of 

 them end in tendons, or thin whitish straps. 

 Sometimes they end in two tendons. The 

 biceps, as it is called in books, a muscle that 

 lies on the arm, and has one end fastened at 

 the shoulder and the other at the elbow, has 

 two tendons at the upper part. 



I will show you an engraving which will 

 give you a pretty correct idea of the shape 

 of the muscle I have just been speaking of, 

 as well as of muscles and tendons in general. 

 You must remember, however, that only a few 

 muscles have double tendons, as this has ; and 

 that they are far from being all of them as 

 perfect and beautiful as this. Some are quite 

 ill shaped, and irregular in their appearance.
