If the animal is yery lame, it should l)e given a narrow stall, and placed in a sling until it can support its weight on the limb. The same treatment is indicated in cattle. It is not adyisable to breed a mare that has had the ileum frac- tured. The bony enlargement that results from the union of the broken ends of the bone may interfere with the passage of the foetus through the pelyic cayity and cause difficult parturition. Luxation of the Patella, " Stifle ;—This is a common accident in horses and mules. Young, immature animals are more prone to displacement of the patella than when mature. The displacement is usually up- ward or outward. Outward dis- placement is comparatiyely rare. The causes of "stifle out " may be described as follows: The patella or knee-cap rests on a pulley-like articular surface belonging to the inferior ex- tremity of the thigh-bone. The external lip of this articular surT face is smaller than the internal lip. The patella is held in place from aboye by the heayy muscles of the anterior region of the thigh, and from below, by straight ligaments that attach it to the leg-bone. If the retaining structures mentioned become relaxed, the patella may, when the limb is extended, become so displaced as to rest on the superior portion of the external lip. Laxness of the muscles and ligaments in young animals is a predisposing factor. Hard work that tires the muscles and causes them to become relaxed, strains, unusual moyements, as kicking in the stable and slip- ping, may cause this accident. Congenital displacement results.
