ON THE DISEASES OF THE HOCK.

First .—That a particular portion of the tibia, and the astra¬ 
galus (before specified), is liable to inflammation and ulceration. 
Secondly .—That it may be diseased with or without spavin. 
Thirdly .—That when diseased, from its greater extent of mo¬ 
tion, it is more likely to occasion lameness than any other part 
of the joint. 
Hid, Fourthly .—That it is most commonly the morbid seat, in 
cases presenting no outward enlargement. 
With respect to treatment, I should consider it of the last im¬ 
portance to put the animal under remedial care as soon as the 
lameness is perceived, when inflammation alone exists, and be¬ 
fore we have reason to infer that ulceration has commenced. 
Bleeding from the saphena vein may be of some service (if the 
vein has sufficient communication with the joint), but counter¬ 
irritation must, I should imagine, be the chief hope, and none 
better than the old means of firing and blistering, continued, 
perhaps, higher up than is commonly the case. A great advan¬ 
tage attending this strong stimulus, has, I think, been generally 
lost sight of; “ it forces the animal for some time to put the limb 
in a state of rest.” I would thank the Editors of The Veterinarian 
to express their opinion, whether in cases of joint disease, gone 
on to a state of ulceration, the articulating cartilage and synovial 
membrane can be again secreted; whether, in short, a cure may 
be effected. The point is as interesting as it is important, either 
as respecting the hock, or navicular joints; and I should imagine 
that Mr. Turner, from his sanguine expectation of cure in cases 
of the latter complaint, is of opinion (though he does not act¬ 
ually express it) that new cartilage and membrane may be 
secreted. If the foregoing observations should induce other 
practitioners to make minute examination of diseased hocks, and 
state their remarks upon them, I do not imagine (though the 
length of this paper requires an apology) that it has altogether 
been written in vain. ~
