cripples during the rest of their lives. But the point is now, Mr. W. thinks, 

 cleared up beyond the possibility of a doubt. 



In the 2d vol. of the Memoirs of the Royal Academy of Surgery at Paris, 

 there are 1 cases related to show the resources of nature, where luxations of the 

 thigh-bone have not been reduced. Here it appears (from examination after 

 death), that in the first case the bone was thrown out upwards and outwards, the 

 cotyloid cavity greatly diminished in size, and its figure changed from round to 

 oval. The head of the femur was received into another cavity formed on the os 

 ileum, under the glutaeus minimus, which served it as a capsula to secure it 

 within this preternatural cavity. This accident was occasioned by a fall when 

 the patient was a child. She was afterwards able to walk about, though she 

 continued a cripple to the time of her death, which happened at the age of 68. 

 In the other case the bone was luxated downwards and inwards, and the head 

 fixed on the foramen ovale. 



There is a case too related in the Edinburgh Essays, vol. 2d, of a man at 

 Worcester, who had the head of the bone thrown out of the acetabulum, and 

 lodged in the groin. It was with some difficulty reduced, and the man suffered 

 no other inconvenience than that of the leg's being about a quarter of an inch 

 longer than the other. 



To these Mr. W. adds, that about 30 years ago his father was sent for to a 

 man who had luxated his thigh bone 3 or 4 days before. The head of it lay in 

 the groin, which the surgeon who was first employed did not discover. How- 

 ever, it was immediately replaced, and the patient recovered the use of his limb 

 in a very short time. 



From what he had said, he would by no means have it concluded that the 

 neck of the bone is not sometimes broken, or that it is not even oftener broken 

 than luxated: but from the case which had fallen directly under his notice, joined 

 to those which he had above recited, he thinks it must appear very clear, that 

 it has been frequently luxated, and that in 2 different ways.
