HOW TO KNOW HIM. 37 



the junction of the knee, are the three carpal-bones, of 

 which we need not speak. In reference to the fore-arm 

 we observe, that it can scarcely be too long, or too 

 heavily clothed upon with nuscles ; for all the muscles 

 which move the leg and foot are located here. Now, 

 please remember that the muscles are the only moving 

 power in the animal, and that all the muscles to lift and 

 extend the foot and leg are placed along this fore-arm, 

 and you will at once conclude that the size and fashion 

 of the fore-arm is a matter of the utmost importance. 

 No strength of shoulder can make good a defective de- 

 velopment of those muscles wrapped around the radius ; 

 because the strength above cannot make good the 

 lack of strength below. Mr. Youatt well says, that, 

 " whatever other good points the animal may possess, if 

 the arm is narrow in front and near the shoulder, flat on 

 the side, and altogether deficient in muscular appear- 

 ance, that horse is radically defective. He can neither 

 raise his knee for rapid action, nor throw his leg suffi- 

 ciently forward." 



The arm should be large at the point of union with 

 the body ; taking a strong hold, as it were, of the trunk, 

 in order to give a sufficient basis for the attachment of 

 muscles. On the back part of the top of the ann, 

 where it joins the body, is a projection of bone, called 

 the elbow. Without explaining the reason why, — be- 

 cause it would require an examination of mechanical 

 principles not within the province of this book, — I 

 would say, that it is of the greatest importance that
