244 THE MODERN HORSE DOCTOR. 



the sheath through which the flexor tendons pass. If seen in 

 its early stage, it would, in all probability, yield to rest and cold 

 Mater bandages. But if neglected until effusion takes place, or 

 the surrounding tissues become injected and thickened, and the 

 horse becomes lame, then a different course of treatment must be

Acetic acid, 4 ounces, 



Powdered bloodroot, 1 ounce, 



Turpentine 1 ounce.

 defines navicularthritis to be " a disease of the navicular joint, 

 giving rise to lameness." 



The Nature of the Disease. — It consists in deep-seated sprain,

Symptoms. — The most important diagnostic symptom is, that 

 the horse generally points the foot, viz., advances it, while stand-
