T^j Sterling, near Cockey Moor, in 
this-county, aged i6, of a fcrophulous habit of body, 
was admitted into the Manchefter infirmary, April 
6, 1768. The account I received with him was, 
that he had been fuddenly feized, about a fortnight 
before, with a violent inflammation in his left Ihoul- 
der, which ’ threatened a mortification, but at lafl: 
terminated in a large abfcefs, which was opened with 
a lancet a few days before his admiflion. The ori- 
fice was fituated near the axilla^ upon the lower edge 
of the peSioralis major ^ and through it, I could di- 
ftindtly feel the head of the os humeri totally divefted 
of its burfal ligament. The matter, which was very 
offenfive, and in great quantity, had made its way 
down to the middle of the humerus^ and had likewile 
burft: out at another orifice juft below the procejfiis 
acromion', through which the head of the os humeri 
might eafily be feen. The whole arm and hand were 
fwelled
