HYDARTHROSIS, 56r 
HyYpDARTHROSIS OF EXTREMITIES. 
L.— Scapulo-Humeral Joint. 
Although very extensible, the synovial of the shoulder-joint does not 
protrude externally when it is dropsical. This condition is accused by 
Jameness and stiffness of' the ex- 
tremity, which is carried forward 
with difficulty ; in some cases, the 
point of the shoulder is deformed 
by a diffuse swelling. The sheath 
of the coraco-radialis, which, in 
Solipeds, is independent of the 
scapulo-humeral synovial, may be 
the seat of a synovitis, sometimes 
mistaken for the lesions of the 
articulation. 
Lines or deep points firing is 
the only beneficial treatment. 
“In tetradactyles, dropsy of 
the articular capsula may be 
manifested by a double soft 
tumor, which appears on both 
sides of the coraco-radialis mus- 
cle, that is, at the antero-inferior 
part of the point of the shoulder. 
‘The reason is that the capsula 
extends downwards and forwards, 
to line the internal face of the 
muscle in question, and that it 
is not longer sufficiently pro-

tected on the sides of this muscle, (from a. photograph. ) 
to be prevented from distending 
on this point when it becomes the seat of a dropsy ” (L. Lafosse). 
Cauterization isalso the choice treatment. 
17--Elbow Joint. 
In his Zrazté de Pathologie, Lafosse wrongly states that this joint is 
never the seat of hydarthrosis. We have seen two cases of it at the 
Alfort clinics; many practitioners have related examples of it. Here is 
.the resumé of one of our observations : 
Five-year-old horse, working for six months. When shown to us, its:
