A Description of all the 
Sea. VII.

In the courfe of the prefent ye.ar 1786, I was confulted by two patients 
with a confiderable colkaion of fynovia within the burfa which is behind the 
infertion of the extenfors of the leg into the patella. 
In both, after the application of difcufling liquors and of blifters had been 
tried in vain, the liquor was drawn off by a lancet-lhaped trocar pafled oblique- 
ly, with the view of excluding the air. 
It may be worth while to remark, that the liquor brought to a boiling 
• heat was found to contain much more coagulable matter than the fynovia does - 
in a found Hate. In one cafe, the operation was palliative only, and was not 
followed with inflammation or pain : but in the other cafe, the whole knee in- 
flamed violently, and fuppurated, probably from the reftleflfnefs of the patient 
and admiflion of the air ; fo that the amputation of the limb became unavoid- 
able. 
It is therefore evident, that the burfae and capfular ligaments of the joints 
refemble each other in their fenfibility, as well as in their flru£lure otherwife, 
and in their difeafes.
