or patella. Each thigh has one bone, each 

 leg two, and each foot twenty-six. 



Besides these fifty-eight in the whole in both 

 legs and the two patellas, there are in some 

 people, at the largest joint of the great toe, one 

 or two small bones, having a slight resemblance 

 to the knee pan, or patella. They are called 

 sesamoid bones ; because they have been sup- 

 posed to resemble the seeds of the sesarnum, a 

 wild eastern plant. 



THE THIGH BONE. The bone of the 

 thigh is called tbefejnur. It is the longest 

 bone in the whole human frame. At its upper 

 end, where it is connected with the hip bone, 

 is a round knob or head. This head fits into a 

 corresponding hollow or cavity of that bone, 

 and is fastened there in a way which will be 

 described in another place. These round 

 heads do not appear quite round enough in the 

 engraving at the head of this chapter. The 

 cut at the part of the book just referred to 

 represents this important part of the human 

 frame much more correctly.
