LESSON VI. 



THE FORE EXTREMITY. 



The general student may not know what is

 to have fore and hind extremities, corresponding 

 to our upper and lower ones.

 only flat bone, and is called the ^scapula' or 

 'shoulder-blade.' All the other bones are of the 

 long kind, except the little bones in the so-called 

 'knee' joint, we have before alluded to in para- 

 graph 11, and one or two little bones we shall 

 afterwards speak of. 



The bones of the fore extremities are of various 

 lengths, and from the top of the arm bone down
