FRACTURES OP BONES. 161 



graph poles, etc. One or both Lones may be fractured. Some- 

 times the bones are driven into the nasal sinuses, and more or less 

 hemorrhage ensues. Bring the bones into position and apply an 

 adhesive plaster over the whole fractured surface. If the bones 

 are driven in, wrap a chamois skin or piece of selvyt around a 

 probe and press the bones into position, care being taken to re- 

 move all detached pieces of bone. If they do not remain in posi- 

 tion, one nostril must be plugged. 



FRONTAL BONES. 



Fracture of the frontal bones takes place from causes similar 

 to those of the nasal bones, and is generally of the variety known 

 as comminuted. The symptoms are a raising and lowering of 

 the bones at each inspiration and expiration, hemorrhage, etc. 

 The treatment requires the adhesive plaster, the removing of the 

 detached pieces of bone, etc. It is best sometimes to wait a few 

 days before moving the diseased bones. 



ORBITAL PROCESS. 



This is fractured by external violence, and sometimes produces 

 opacity of the cornea. Bring the bones into position, apply plas- 

 ters, and remove the small portions of detached bone. 



Fracture of the internal plate of the frontal bone is caused by 

 external violence. In receiving the injury the animal usually 

 falls to the ground, remains down for a few minutes, then gets 

 up and appears all right, but in a few days brain symptoms are 

 presented. 



Treatment. — Keep the patient quiet and endeavor to raise the 

 bone. Use cooling food and cold applications to the seat of in- 

 jury. The prognosis is unfavorable. 



PARIETAL. 



Fracture of the parietal bones occasionally occurs, and death 

 results. The operation of trephining and removing the piece of
