the disease had progressed far enough, you would 

 find the history of the case quite different, and your 

 subject presenting if the form was acute, consider- 

 able constitutional disturbance with an elevation of 

 temperature, visible membranes injected, constipation 

 present, feces altered in color, respiration accelerated, 

 with lameness of a peculiar kind; and if located 

 around those joints not well protected by muscles 

 giving attachment to tendons, heat, swelling and 

 tenderness upon pressure will exist to a degree. 

 These latter symptoms are due in all probability to 

 rupture of some of the tendinous fibers from their 

 bony attachment, while the partial removal of the 

 articular cartilages which occurs, is sufficient to 

 account for the lameness. 



Again, if the animal affected does not develop at 

 all the facial enlargements, the first symptoms made 

 manifest usually are of the most acute kind, shown 

 by extensive tumefaction around the joints, with 

 evidence of positive rupture of tendinous attach- 

 ments; complete possibly, and probably, fracture or 

 rather a tearing away of some part of the bone itself, 

 which occurs in all probability from muscular con- 

 traction or undue weight being thrown upon it. 

 The proximal end of the humerus will show con-

 would present the same changes. In fact, it is in
