SHOULDER LAMENESS. 



There are three forms of shoulder lameness, which may exist 

 independently of each other. One of them is illustrated in 

 Photo-lithograph, Plate II., Pig. 1. These three causes are — 

 (1st.) Disease of the shoulder-joint. Photo-lithograph, Plate III., 

 Fig. 1 ; (2d.) Sprain of the flexor brachii, Photo-lithograph, 

 Plate I., Fig. 5 ; and (3d.) Sprain of the antea and postea 

 spinati, teres major and minor, muscles, but more particularly 

 of the spinati, as they are mostly concerned in performing the 

 function of binding ligaments, connecting the scapula and the 

 humerus. 



Mr. Percivall and others were of opinion that injury to the 

 serratus magnus was a frequent cause of shoulder lameness. 

 Professors Dick and Barlow taught that such could hardly 

 be the case, and my experence leads me to endorse their 

 opinion. 



The three above mentioned are the usual causes, but there 

 are others sometimes met with, namely, rheumatism; liver 

 disease ; formation of abscesses in the brachial glands, as a 

 sequence to, or sometimes a primary manifestation of strangles ; 

 open joint and necrosis of scapula. — (See Photo-lithograph, Plate 

 I, I'ig. 6.) 



Disease of the Shoulder-Joint may arise from a variety of 

 causes, as sprains or rheumatism. Inflammation having been 

 set up in the structures of the joint; the capsular ligament
