74 DISEASES OF 



FRACTURE OF THE ILIUM. 



THE illeum is seen at 13 iii the figure of the skeleton. 

 Next to fracture of the lower jaw this is the most fre-

 is broken off from the main bone ; at other times only 

 a small piece is chipped off. 



Causes. External violence, such as catching the pro-

 moved about. The animal will be slightly lame at first 

 which soon increases and may become quite pronounced. 

 There will probably be some pain on pressing on the 

 illeum. If a string is passed from the middle of the 

 spine to the point of the illeum that has not been in- 

 jured and the exact measurement taken, it will be found 

 to be longer than the measurement when taken on the 

 side of the fracture. 



Treatment. Rest, and the application three times a 

 day of HEARD'S AMERICAN EMBROCATION, well rubbed in. 

 This to be continued until the quarter is well blistered. 

 With this treatment these cases always become useful 

 for slow work and often make good driving horses. To 

 a close observer, however no matter how small a
