consistence of soft cheese, and in part an orange yellow fluid, 
of which last the quantity was about half a pint, and which, 
on standing, deposited a copious (much lighter yellow) sedi¬

had destroyed the tube v cular body, crypts or cavities only 
remained, filled with this fluid alone. From wherever these 
changes had taken place, organisation had altogether dis¬ 
appeared ; nor did it exist but in very low degree in parts 
which had not yet become converted. The tumour appeared

Synovitis , with Open Joint. 
From a good many cases of the above, which I have 
treated, I am inclined to think that, generally, the open 
joint receives undue anxiety and attention from the veteri¬ 
nary surgeon ; while the synovitis (the real evil) is thus 
thrown into the back-ground. 
The principal effort of treatment, in all the treatises I have 
read, is directed to closure of the wound , mechanical or natural; 
which, at first, I have found rather injurious than otherwise. 
I tried the experiment on a case I had last December, 
where the wound was on the outside of the back, by putting 
a compress on the opening; and, instead of removing it
