ANIMAL MANAGEMENT. 



The roiifided end of the coronet bone meets the large smooth surface, 

 on the top of the rear slope of the coffin bone, and rocks to and fro on it 

 as the foot is moved. 



A thick layer of gristle covers those parts of the bones which meet 

 each other, and the whole joint is bathed in "joint oil" to make it work 

 smoothly. 



The cartilages. — Attached to and extending from near the top of the 

 coffin bone on each side, continued all along its edge, and curving round

Liga-

the heel beyond, there is a large springy piece of gristle {the lateral 

 cartilage\ fig. 42. In a fine skinned horse its outline can be clearly seen, 

 extending along the sides of the coronet, and its "spring" may be easily 

 demonstrated by pressing hard on its edge at the heels. 



Ligaments of considerable strength pass from bone to bone ; holding 

 them firmly in position, yet permitting all necessary movements. 



Tendons. — Starting from muscles in the arm above, these run down the 

 limb, both in front and behind, and are attached firmly into the bones. 

 In front there is only one, which is spread out on the pastern and the top
