CORONET
—is the part surrounding the foot of the horse just above the junction of hair and hoof: the bone from which the name is derived, bears great affinity in form to a ducal coronet, and is situate between the lower part of the fetlock-bone and the coffin, into which it is inserted, jointly supported by the nut-bone behind. Ligamentary twists, or distortions, sustained at the superior junction of the coronary bone, frequently occasion a prominence upon the coronet, which becoming first callous, and then ossified, is termed A RINGBONE.
