30 HOW TO JUDGE A HOUSE. 



tion of the wliole columu takes place, and, -with it, a 

 tossing, elastic action, tliougb, on account of the 

 sliortness of the angularly connected bones, with 

 less force than that produced on the hind leg. 



The elbow joint must, therefore, be considered as 

 the h^.icl: joint, that is, the spring joint of the fore leg. 

 "^'ith tjie stille-ioint it lias nothing else in common 

 exce])t being in position of nearly equal height on 

 the rump, the necessity for which there are other 

 reasons. The knee cannot be compared with the 

 hock, because a spring-like action can never be 

 produced by a joint, which, while the leg is in 

 the moment of supporting, permits no consider- 

 able angular variations between the connecting 

 bones. For the better understanding of these 

 facts, the drawing (Fig. 1") is added. The cor- 

 responding joints : shoulder and stifle joints, elbow 

 and hock joints, and the two fetlock joints are 

 connected by dotted lines, while the various bones 

 of equal value are marked by letters : a and «', etc. 

 Especially observe the two lever projections of 

 the elbow and the hock (c and c) so as to become 

 convinced that it is from there that the propelling 

 and the tossing power of the muscles for fore and 

 hind leg is developed in exactly the .same manner; 

 and that the comparison of the respective parts of 

 the legs is correct.
