318 ARTHRITIS— GOUT, 
In tho lour articulations of the fetlocks a purulent serous 
matter was found of a grey colour, and in a very considerable 
quantity. The synovial capsules of these articulations presented 
on their inner face traces of inflammation, but less decided on the 
cartilage than where the points of the synovial membrane are 
free. The articulations of the knee exhibited the same lesions 
as well in the augmentation of the synovial fluid as in the in- 
flammation of the lining membranes. The articulations of the 
hock were in a healthy state. 
The tendo-perforans of the left fore foot presented at its pos- 
terior part, and a little above the fetlock, a black patch, an inch 
in length, and reaching across the tendon. There existed ano- 
ther on the perforatus tendon, and precisely at the corresponding 
situation. A little below the channel between the sessamoids, 
the tendon was ruptured, and each of the ends was rough- 
ened and black. Above and below the rupture were several spots 
of inflammation, and also about the suspensory ligament, and 
all the ligaments belonging to the fetlock. Every part also of 
the cellular substance connected with the joint partook of the 
inflammatory disorganization. 
The pastern joint presented lesions of the same nature as 
those of the fetlock, and there was a separation of a quarter of 
an inch between the cartilaginous surfaces of these bones, and 
particularly at the anterior edge. There were not, however, any 
concretions similar to those found in the joints of the human 
being. 
This case appears to M. Ollivier to have much resemblance to 
the gout of the human being, not only in the change of inflam- 
mation from part to part, but in the lesions which were after- 
wards found in the articulations which were the seat of disease. 
The infiltration of the ligaments, and of the fibrous tissues which 
surround the joints — the altered character of the synovia — the 
traces of inflammation in the synovial capsules, and the occa- 
sional caries of the cartilages— these are very striking points of 
resemblance. It is true, that there were not the chalky concre- 
tions which are met with in the human being, nor the return of 
the fit : but who can tell that, if this disease had not been attend- 
ed by complications that destroyed the animal, it would not have 
returned, and with it the chalky concretions, and the caries of 
the articular cartilages ? 
It may, perhaps, be objected to me, that if I believed there 
was so much analogy between this disease and gout, I should 
not have had recourse to cold bathings. I reply, that the lame- 
ness came on suddenly, and, shifting from one limb to another, 
j was afraid that acute founder would soon follow. 1 soon,
