LAMENESS, FROM VARIOUS CAUSES. 341 
im tas furm which they long afterward preserve. For the most 
part, chronic disease and lameness are not marked by any violent 
symptoms, nor are they accompanied with much pain, if the horse 
be kept at rest. 
Suppose the disease to have first made its appearance, the parta 
will be hot and jsainful; but the idea of curing ring-bone—that 
is, restoring the parts to their normal condition—is really absurd ; 
for, when once the bones are anchylosed, the joint never can per- 
form its natural function again. The new growths (exostosis), 
and the changes of structure that occur within and about the 
region of disease, are a part of Nature’s own handiwork, in view 
of strengthening a weak bone or joint. Our object in the treat- 
ment, therefore, is merely to aid Nature. Excuse the animal from 
work, and apply sedative lotions (cold-water dressings) so long as 
the acute stage lasts; then, when the case passes into the chronie 
stage, apply counter-irritants for a week or two, and, finally, turn 
the patient out to grass, The following will be found an effective 
sedative lotion:

Apply once or twice daily, until a crop of pustules appear ; then 
omit the application, and reapply it at the expiration of two or 
three intermitting periods. 
The remedies used by veterinary surgeons generally, are oil of 
eantharides, acetate of cantharides, blistering ointment, ointment 
of hiniodide of mercury, and, lastly, the actual cautery, or heated 
iron. I have tried all except the latter, which savors too much 
of barbarity, and I never found any thing to equal the preparation 
here recommended-—namely, cod-liver oil and kerosene.
