LESSON VL 



THE FORE EXTREMITY. 



The general student may not know what is meant 

 by the fore extremity, so I shall have to explain it. 

 Our arms and hands are called our upper extremi- 

 ties, our legs and feet our lower extremities. The 

 words upper and lower being used on account of 

 our upright position of body. Quadrupeds having 

 horizontally placed bodies are said to have fore and 

 hind extremities, corresponding to our upper and 

 lower ones. 



43. — The horse's fore extremities are made up of 

 all three kinds of bones, long, flat, and irregular. The 

 topmost bone is a flat bone, and the 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 paragraph 11, and one or two 

 little bones we shall afterwards speak of.
