around it pretty freely. This, and confining her some weeks in 

 a box, effected a cure. 



[I lately met with a case of this description which arose from 

 severe struggling after being thrown for an operation. The 

 use of the limb was nearly lost for several days, and the seat of 

 injury was evidently in the triceps muscle, just above the elbow, 

 which became much enlarged. Fomentations, bleeding, and 

 stimulants effected a recovery. 



The symptoms of shoulder lameness are generally detected 

 without much difficulty. The horse is generally lame in the 

 walk as well as the trot, which is not the case with other lame- 

 nesses of equal severity. The lameness is particularly notice- 

 able on going down hill. Unlike other lamenesses, the injured 

 leg is not extended so. far as the other, and is often carried 

 forwards in a circular direction ; there appears, indeed, greater 

 pain evinced in extending the limb than in resting the weiglit 

 of the body upon it. On moving the limb forwards, backwards, 

 and laterally, there is often considerable pain evinced by the 

 animal ; this, however, depends on the severity of the case. 



Horses with thick, upright, and badly formed shoulders are 

 more liable to these injuries than others, from the inability of 

 the parts to respond adequately to exertions demanded, whence 

 they become over exerted and strained. The injuries are there- 

 fore produced in galloping over heavy ground, or over ruts, or 

 going fast down hill in harness, or from some accidental or false 

 step. 



The treatment should consist of bleeding largely from the 

 plate vein as it is commonly termed, just opposite the elbow- 

 joint; three to five quarts may be abstracted with advantage. 

 Should there be considerable pain, and particularly if the parts 

 feel hot and tender, the shoulder should be fomented f?-equently 

 with warm water for a day or two, after which the following 

 liniment should be well rubbed in ; but if there be no visible 

 heat the liniment may be rubbed in at first : — 



Olive oil 2 ounces. 



Spii'its of hartshorn 1 ounce. 



Strong tincture of cantharides ... I ounce. 



Mix. 



"VYe may produce by this liniment what degree of effect Ave 

 please, by rubbing in a greater or lesser portion. If the case 

 be severe, and the temporary loss of hair no consequence, the 

 greater portion may be rubbed on in one day, and a lesser por- 

 tion the next, which will be found to produce considerable 

 swelling and discharge of serum. Its strength may be increased 

 by the addition of the last-mentioned ingredient, and diminished 

 by the addition of the first. In slighter cases one fourth of the
