4. Sex. 



It has often been asserted that sex has influence as a pre- 

 disposing cause, and that horses are more liable to the 

 defect than mares. This notion was started by Girard, jun., 

 and is ahuded to by Percivall, who writes : " Mares seldom 

 become Koarers, at least in comparison with horses. This 

 is a fact, I believe, too notorious among men of horse 

 experience to admit of doubt, though it is one for which it 

 appears diflicult, if not impossible, to assign any satisfac- 

 tory reason. However, as I am informed, so stands the fact."
