 tablespoonful to one pint of distilled water or Bichlo-

 as it predisposes him to splints. The weaker the bones 

 of the hock in comparison to the weight of the body the 

 more inclined will the animal naturally be to contract

Symptoms: Spasmodic catching up of the spavined 

 limb, the moment the heel of the foot touches the ground,
