the round head, with its cartilage, is wanting ; and, 
I believe, there are few inftances where the whole 
head of any bone is fo entirely deftroyed, in two or 
three weeks (*z) by a cartes, as that drawing repre-

capfular ligament, remained in a found ftate. We 
fhall be farther confirmed in this opinion, if we 
attend to the defcription he has given of his mode of 
performing the operation, (vide p. 58.) where he 
fays, “ that he began his incifions at the orifice

little over the joint, his beginning his incifion below

mary turner, a farmer’s daughter, of ipstones, 
in this county, applied to me in October 1771, on

with which fhe had been afflided near three years. 
Upon examining it, I found three apertures; two

the third, near the infertion of the pedtoral mufcle 
into the humerus. By introducing two probes, from 
the upper and lower orifices, they eafily met in the 
joint, the opening into which, through the liga- 
ment, feemed to be very fmall, and X could per-

cafe, there feemed nothing to be propofed for her 
relief, but either to amputate the arm ; or, by
