130 THE GROUSE IN HEALTH AND IN DISEASE 



In each case the fracture was comminuted. The shortening 

 in one leg was from 83 mm. to 76 mm. The union in each was 

 effected by an irregular and immovable mass of bony matter 

 thrown out to include the fibula which is also greatly thickened. 

 The first case (see Fig. 9), was that of a cock bird which 

 lived to be shot on January 7th, 1907, weighing 20 ounces.

The fractured end of the bone had been rendered smooth by 

 absorption, and the deformity caused by overriding of the 

 lower fragment had been partly obliterated. In another case 

 (see Fig. 10), the upper fragment was united to the lower at an 

 angle of 30 degrees. Figure 11 was obtained from a cock, 

 found dead in November 1907, having succumbed to Strongy- 

 losis. The shot which caused the damage can be seen to the 

 left impacted in the bony mass.
