Fractures in the Lovjer Animals. 183 



3. 393. United Fracture of the Femur of a Domestic Fowl. 



— Right femur of a domestic fowl — macerated, showing the 

 mode of union. The broken ends have overlapped greatly, and 

 the lower fragment has been rotated outwards. A bridge of 

 new bone unites the adjacent parts, and the medullary cavity 

 in each case has been covered in by new bone. G. C. 1540. 

 Presented by Dr Gairdnee. 



3. 394. United Fracture of the Tibia of a Pheasant.— 



Right and left tibia and fibula of a pheasant — macerated, 

 showing a united fracture of the right. 



The bone is shortened by half an inch, and there is a great 

 deal of thickening round the seat of fracture. G. C. 3256. 

 Presented by Chaeles W. Cathcart, F.R.C.S.E. 



3. 395. Ununited Fracture of the Neck of a Fox's Femur. 



Left femur of a fox — macerated, showing changes following the 

 above injury. 



The neck of the bone has entirely disappeared, but at the 

 seat of fracture much irregular new bone has been thrown out, 

 and partly fills the hollow of the great trochanter. The adjacent 

 surfaces of the remains of the head and of the root of the neck 

 have been eburnated by friction. The remains of the head, which 

 was loose, and is now attached to the bone by a wire, shows 

 great irregularity of the articular surface. These changes 

 resemble those found in arthritis deformans. G. C. 1754.

3. 396. Compound Fracture of the Femur of a Rabbit.— 



Left femur, apparently of a rabbit — macerated, showing 

 changes after the above injury. 



At the seat of fracture some of the original shaft is shown,
