We have now reached a stage where it becomes necessary to subject the legs to careful manipulation in search of defects which may not hitherto have been patent.
Capped elbow (Vol. II, p. 359) will, of course, be perceptible at a glance. It is of varying importance. Sometimes, when of recent formation, and attended with inflammation and lameness, it would constitute unsoundness, but after the inflammatory action has subsided it becomes merely an eye-sore, unless of course it is large and specially liable to injury from the cause which produced it. Before proceeding down the limb the finger should be directed to the seat of median neurectomy (p. 165 of this volume), when evidence of the kind referred to in connection with other neurectomies may be discovered (see Fetlock, p. 377).
As we pass down the leg we may meet with sprain or rheumatism affecting the muscles of the arm, and the only evidence of it then present may be a tenderness to pressure along their course with more or less lameness. The writer has in mind the case of a horse which he knew went sound on one day, and was quite lame from this cause on the next.
