 scratching, and tearing the wool off their back and sides, 

 they will scarcely ever be seen grazing or lying down 

 quietly and remasticating their food, as is the case with 

 sheep in perfect health. This disease in sheep is the same 

 as mange in horses, dogs and cattle ; and it is the result of
