ABNORMAL CONDITIONS OF THE SHOULDER JOINT. 619 flammation of the membranes of the brain, and Dr. Smith* made the post-mortem ex- amination. Upon entering the room his attention was attracted by the appearances which the shoulder joints presented. The de- viations from the normal state were most remarkable at the left side. The muscles of the shoulder and arm were atrophied, the acromion process projected considerably, and the head of the humerus could be perceived lying a little beneath the coracoid process, the apex of which was in a line with the bicipital groove of the humerus. The na- tural roundness of the shoulder did not exist, and the elbow could be readily brought into contact with the side. The right shoulder joint presented similar appearances, but in a slighter degree; the head of the humenis was not placed so directly beneath the coracoid process ; but the flattened form of the shoul- der, the atrophied muscles, and the projection of the acromion, all indicated that the condi- tion of the joint was nearly similar on both sides. From the last circumstance, and the absence of any external sign of disease, it was concluded that the deformities were the result of an original or congenital malformation. The anatomical examination of the joints confirmed this opinion. Upon the left side there existed scarcely any trace of an arti- cular surface in the situation which the gle- noid cavity occupies in the normal state ; but there had been formed on the costal surface of the scapula a socket of a gle- noid shape, measuring an inch and half in its vertical direction, and an inch and a quarter transversely. It reached upwards to the under surface of the coracoid process, from which the head of the humerus was merely separated by the capsular ligament, there being no interval between the summit of the abnormal socket and the coracoid pro- cess. Around this socket the g/enoid liga- ment, perf
