ELBOW-JOINT LAMENESS. 233 



Post-mortem Account. 



The Elbow Joints proved the seats of disease. The infe- 

 rior or broader half of the articulatory surface of the ulna presented 

 a patch of ulceration, of the shape of a square whose sides mea- 

 sured about an inch each. The transverse portion of the articu- 

 latory surface of the radius, which naturally is an eminence, had 

 become a fissure of ulceration of about a quarter of an inch in 

 breadth at its widest, which was its posterior part : this ulceration 

 extended but little more than half way across the surface, the 

 portion of surface in front of it being sound. There was likewise 

 a patch of ulceration in the interval between the condyles of the 

 humerus, of a triangular shape, but which, in that situation, 

 would not be opposed, either in action or at rest, to the ulceration 

 upon the ulna. There was a patch of discolouration upon the front 

 of the outer condyle, a seeming precursory to ulceration. From 

 the surface of the ulcer upon the olecranon there were granula- 

 tions springing up, which, it is to be believed, would in the course 

 of time have turned osseous, and formed the nucleus for an an- 

 chylosis of the joint. In this instance, however, there existed no 

 disease whatever of the periosteal or ligamentary tissues outside 

 the joint, though I believe that would speedily have supervened 

 upon the morbid condition afore described. 



At no period of the duration of time the case was under treat- 

 ment — seven months — was any satisfactory opinion given of the 

 lameness, or the seat to it. The lameness came on very gradually, 

 in a manner imperceptibly, and fluctuated in intensity, being 

 sometimes more evident than at others. It followed no hard 

 day's work or known injury. And it increased, though tardily, 

 by degrees from first to last, and in the face of all kinds of treat- 

 ment (to parts not affected), until at length it became intolerable. 

 And so mysterious was its nature all the way through the case 

 that nobody, by the merest conjecture, ever hit upon its seat. 

 And yet, when its seat and nature came to be developed and con- 

 sidered, the symptoms appeared such as might have indicated it; 

 and, moreover, inclined to the belief that there possibly might have
