68 TEE HUMAN BODY 



soft parts also are lacerated, so that there is an opening 

 from the skin to the broken bone, the fracture is com- 

 pound. 



Once a bone is broken the muscles attached to it are 

 apt to pull its ends out of place ; hence it requires to be 

 " set," and then kept in position by splints or bandages; this 

 frequently needs much skill and a thorough knowledge of 

 the anatomy of the body. A medical man should be sum- 

 moned at once, as the parts around the break commonly 

 swell very rapidly and make the exact nature of the frac- 

 ture hard to detect, and also the replacement of the dis- 

 placed ends more difficult. 



Why does a broken bone need " setting "? What is the object of 

 " splints "? Why should skilled assistance be obtained as soon as pos- 

 sible after a bone has been fractured? 



APPENDIX TO CHAPTER IV. 



When giving lessons on Chapters III and IV, it is very desirable 

 for a teacher to have at hand an articulated human skeleton. This 

 may be purchased for about $40.00 from Henry Ward, Rochester, N. 

 y., and will last for an indefinite number of years. When the school 

 funds do not permit the purchase of a skeleton, one can almost cer- 

 tainly be borrowed from some medical man or medical school for a 

 few days. When there are several public schools in a city it would 

 probably be possible to induce the school commissioners to purchase 

 a skeleton to be used by the schools in turn.
