Over-Reach, in farriery, signifies a wound upon the coronet, towards the back part of the foot, or heel of a horse : it is occasioned solely by striking the sinew of the fore-heel with the toe of the. hind-shoe on the same side; in consequence of which the animal halts, or walks lame.- See Halting.

Young horses are very apt to cut. their heels when travelling; as their hind-foot moves in the same direction with the fore-foot; and as they are generally too spirited in their first excursions.

Although an over-reach is a wound of the complicated kind, yet it is not attended with danger, provided proper applications be made, to induce a suppuration. For this purpose, the most efficacious external application will be a proper poultice :- take oatmeal, or coarse wheaten flour ; digestive ointment (prepared of equal parts of common turpentine, and hog's-lard), two ounces ; beer-grounds a sufficient quantity. This may be repeated at least twice in twenty-four hours, till the wound be well digested, smooth, and free from cavities, or excrescences of proud flesh. Next. the surface of the bruised part should be sprinkled over with the following mild escharotic powder : - Take of burnt lime-stone slaked in the open air, three ounces ; and Armenian bole, one ounce : triturate these ingredients in a mortar, and pass them through a fine sieve. - After sprinkling the wound with this powder, a pledget of dry lint may be laid gently over it; and, when the surface of the contusion is nearly equal with the skin, the powder alone will be sufficient to effect a cure.
