cutaneous quittors ; if the pus has filtrated into the synovial 
sheaths, tendinous or articular, it gives rise to tendinous 
synovitis, and to traumatic arthritis. In muscular interspaces 
suppuration may become very abundant, weaken the patients, 
spread extensively, give rise to extensive sloughing and terminate 
by septic infection. 
Round the rectum, abscesses may extend towards the depth of 
the cavity into the loose cellular tissue and open in the peritoneum, 
to soon give rise to fatal complications. It is the same for those 
which are formed in the thickness of the abdominal walls, in the 
ganglions of the groin or in the testicular cord after castration. 
Those developed in the thickness of the walls of the chest and 
in the prepectoral ganglions may similarly produce pleurisies no 
less difficult to cure. 
M. Ch. Martin cites several similar cases. 
He has found these abscesses in the sub-lumbar and the bron¬ 
chia] ganglions. Probably other practitioners have. I have 
observed several cases myself. 
What are the causes of these abscesses, whose consequences 
are so serious ? Such is now the question to solve, as from it 
will come the indications necessary to follow to prevent them 
They all are due to two causes. The first acts in all cases; it 
is the pyogenic attitude of the horse, upon which I have already 
treated. 
The second varies as whether we consider the subcutaneous and 
intermuscular abscesses or those of the lymphatic ganglions. For 
the former it must be a contusion more or less powerful, or some 
violent external action exercised on the region. It may even be 
said that by this means, one could produce experimentally at will 
upon a gourmy horse, similar purulent collections. For the 
latter, the occasional or determining cause, probably unique, is 
the absorption by the lymphatic vessels and the accumulation in 
the ganglions of the phlogogenous products resulting from the 
pathological exudation from the sores, or perhaps contained in the 
purulent cavities, or open externally. This a fact which belongs to 
no special disease. It can take place in all cases where the 
necessary condition of its development is existing, to wit: the
