Shrinking of the muscles comeson early and is a constant symptom; tenderness topressure may be found over the outer anterior aspect 228 of the head of the humerus, and pain may be com-plained of at the insertion of the deltoid. The progressof the disease, unless aided by art, is from bad to complications are abscess and subluxation. Thetendency of the tuberculous abscess is the same as else-where.

Chronic abscess in the shoulder-jointescapes through the least protected parts of the capsule,and is subsequently directed in its course by structureswhich form a large shield over the joint. The joint is 229 supported and protected by two successive muscularcoats, the first or deeper being intimately associatedwith the fibers of the capsule, the superficial protectionbeing the deltoid muscle. The muscles touching thecapsule consist of the subscapularis, long head of triceps,supraspinatus, infraspinatus, and teres minor, the threelast being intimately blended into a continuous mass.
