strange food of any kind, inducing indigestion. In all these cases, the 

 symptoms of the lameness are much alike, the limb is carried stiffly, 

 and swung in a round-about outward manner, with dragging of the 

 toe. To detect from what source it arises, the history of the case is 

 necessary, accompanied by the eye and finger of an expert. It may 

 be from any one of those already enumerated, or others not mentioned, 

 so that a careful and proper examination must be made before any 

 treatment is adopted. If from injury, cold water irrigation daily, 

 followed by blisters and long rest, should be resorted to ; if from 

 indigestion, or change of food, one ounce of carbonate of soda daily, 

 for a few days, in the food, will be found very beneficial. 



140. The Shoulder Joint is also frequently the seat of disease, either 

 from injury of the joint itself or through the muscle — Flexor Brachii 

 — as it passes over the head of the humerus, being sprained, or from 

 the sprain of some of the muscles in the near neigbourhood of the 

 joint. The point of the shoulder is occasionally damaged by the 

 animal running against some hard substance, such as a stone wall, &c. 

 Any one of these injuries causes great pain, lameness, and enlargement 

 of the parts.

 applications of water may be tried, followed by blistering. Setons act 

 well at tunes in such cases, with a run out on grass. 



142. Again, shoulder lameness may be due to Rheumatism, a 

 disease that is both acute and chronic, and which may be regarded as 

 being due to some peculiarity in the blood, the exact nature of which 

 is not as yet known. Nearly all the structures of the body are subject 

 to its baneful influence. It is not, however, so common in the horse 

 as in the human subject, but, from long observation, I have met with 

 it m certain breeds of horses, and have generally traced it to hereditary 

 causes, and have usually found it associated with heart affections. 



143. As in the human subject, Treatment of Rheumatism is not 

 very satisfactory, but when much pain and constitutional fever are 

 present, ounce doses of Sulphate of Magnesia or Sulphate of Soda, along
