 flatness. The bigness is really so. Now to all squares 

 there are four sides and four angles, and so in our square

 you find them formed by — 



1. The internal maleolus (Fig. 6,'). 



2. The point of the hock (Fig. 6,^). 



3. Head of tibia (inner anterior aspect) (Fig. 6,^). 



4. Head of inner splint-bone (Fig. 6,*), 



Please to notice that the last three of these never alter 

 their relative positions. You do not find the point of 

 the hock approaching or receding from the head of the 

 inner splint bone ; neither do you find the head of the 

 inner splint bone approaching or receding from the inner 

 anterior aspect of the head of the tibia. These points 

 are always the same distance from one another. The re- 

 maining point, however, formed by the internal maleolus, 

 approaches ^ and recedes from ^^ whenever the hock 

 bends {see Fig. 7), when our square disappears. So that
