Modern surgery, general and operative . g fromunder the latissimus dorsi muscle, but it is now known to be due to paralysis ofthe serratns magnus muscle, the bone being acted upon by the trapezius, pecto-ralis minor, levator anguli scapula?, the rhomboid muscles. Examination showsthat the scapula will not rotate normally forward. This is demonstrated by ex-tending the arms in front to a right angle, the gliding forward of the scapula uponthe sound side being marked, but upon the diseased side being slight or absent. Treatment of paralysis of the serratus magnus muscle comprises massage,electricity, passive motion, and deep injections of strychnin. Katzenstein advocates operation for serratus palsy. He makes an incisionnear to the midline of the back, exposes portions of origin of the trapezius andrhomboideus major, divides them, carries the cut muscles downward and out-ward, and sutures them to the periosteum of the seventh, eighth, and ninth ribsand to the latissimus dorsi. He then makes an incision along the inner surface.

Dislocation of the Humerus (Shoulder-joint).—This mjury is quite fre-quent because of the free mobility of the shoulder-joint, its anatomical in-security, and its ex-posed situation; it rarely occurs in the very young and inthe aged, and is oftenest encountered in muscular young adults. _ Shoulderdislocation is produced by throwing the arm into abduction. In this positionthe head of the humerus presses against the lower and front part, that is,agamst the thinnest and most poorly supported portion of the capsule. Inalmost ah cases the tear in the capsule occurs between the tendon of the sub-sc
