BLOOD SPAVIN
—is a preternatural and puffy enlargement on the inside of a horse's hock, proceeding from a distension of the vein crossing the internal junction of the inferior part of the thigh bone with the superior part of the shank; and whenever such injury is observed, it may rather be supposed to have originated in a blow, a kick, or more probably from a ligamentary twist or distortion, (by a short and sudden turn in the small stall of an ill constructed stable,) than by any continued exertion of speed, either on a journey or in the chase.
