The' three inferior sesamoidean hgaments were ruptured on the 

 same hne at their upper insertion. Here again the ligaments had torn 

 away the portion of bone to which they were attached. The internal 

 sesamoid was fractured transversel) . 



There were no other bony changes. The lower extremity of the 

 metacarpus and the first phalanx were intact. The synovial capsule 

 of the joint was torn and ecchymosed throughout the greater part of 

 its surface. Finally, there was a great difference in size between the 

 two terminal branches of the superior sesamoidean ligament (suspen- 

 sory ligament) ; the internal was chronically inflamed, and double the 

 size of the external. 



Most of the lesions in the right fetlock were similar to those above 

 described. Both sesamoids showed comminuted fracture.
