    Dissection A very careful examination of the elbow was made, under my superintendence, by my pupil, Mr. Edgar Browne, with the following results:— Bones.—The ulna was dislocated forwards, so that the up- per surface of its olecranon process became placed in front of the capitellum humeri, and had thus assumed the position na- turally occupied by the head of the radius during flexion of the forearm. The radius was supinated and maintained in situ naturale—as regards the ulna—by the coronary and interos- seous ligaments being intact. Ligaments.—Of the anterior ligament, the only part remain- ing at all perfect was a shreddy portion about the centre; all the rest of it had been torn through. The posterior, and both lateral ligaments were completely divided. The coronary and oblique ligaments were uninjured. Muscles.—The triceps extensor was detached from all its points of insertion. The supinator radii longus was uninter- fered with at its origin; but the two radial extensors of the carpus beneath it were torn away from the surfaces whence they spring. All the muscles which arise from the external condyle—with the exception of the supinator radii brevis, and
