 inside of the hock-joint, either by 

 feeling or comparing it with the 

 other joint, will show an enlarge- 

 ment, or bunch, that may vary 

 in size, according to circum- 

 stances. The size of the bunch 

 does not indicate the severity of 

 the disease. The most severe 

 cases of spavin (occult) may oc-

 horse usually rests the spavined 

 leg by carrying the foot slightly

 joint a little. Figs. 43, 44. 



In treating spavins, the ob-

 inflamed, reduce the inflammation
