SHOTJLDER LAMENESS. 



There are three forms of sLoulder lameness, wliicli may exist 

 independentljr of each other. One of them is illustrated in 

 Photo-lithograph, Plate II., Tig. 1. These three causea are — • 

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

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

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

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

 of the spinairi, as thej are mostly concerned in performing the 

 function of binding ligaments, connecting the scapula and the 

 humerus.

 Profes-sors 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

 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
