BONES OF THE SKELETON. 



The following is a list of all the bones of the skeleton, with the 

 parts of the body in which they are found. The bones printed in bold- 

 faced type are single bones ; all others are in pairs. The numbers in 

 parentheses represent the number of bones of that kind. Where bones 

 are in pairs the numbers should be, of course, doubled to give the 

 total number; for example, "Ribs (13)" means thirteen ribs on each 

 side, twenty-six in all ; but "Cervical vertebrae (7)" (bold-faced type) 

 means that there are only seven in all.
