BONE SPAWN.

From a paper by Mr.. James Mclaughlin
the Montreal Veterinary Medical Assacia
ton, we make the following extracts:
"Bone SPAWN as a rule produces lame
ness, sooner or later. Although so few
cases have come under my observation
where one or both hooks bore thoroughly
developed spayins, and yet for a number OF
years showed no lameness therefrom. ]
cannot but maintain that when we have
such direct interference with this most i'm
portant and complicated joint, it will some
day cause lameness; and whether the lame
ness attends its early formation or subse-
quent growth, once bone is thrown out, the
disease becomes established, and the ami
NAL is rendered unsound through life. The
lameness attendant on this disease is very
remarkable, and easily distinguished from
any other. The animal, on starting, draws
the limb up with a quick, sudden motion,
and yet there is an evident dragging Of the
leg, indicative of pain, and a loss of action
In the joint. AS the horse proceeds on his
journey, a perceptible reduction ofthe lame
ness ensues, and when quite a distance is
travelled, it very often disappears entirely;
but allow the animal to again rest, and on
starting anew a recurrence of the lameness
takes place. The departure of the lameness
depends not only on the amount of exer-
else, but principally on the extent of growth
in the SPAWN; if be newly forming, the
lameness may cease after a few. miles have
been travelled, but if it has acquired consid-
cradle growth, exercise will but slightly
abate it. The degree of interference with
the action OF the joint by the bony deposit
determines the extent of the lameness.
which is further aggravated by the difficulty
experienced by the periosteum in
dating itself to the bony growth beneath it.
Veterinary practice in the treatment of this
disease presents a wide field for differences
OF opinion to arise, and this difference is
based solely on one fact. They all agree
upon the necessity Of reducing the inf1am-
nation as far as possible as a primary step,
also upon the advantage derived from ele-
Vaung the caiKings, whereby tensinn is re-
moved from the joint, and further the ulti-
mate and unavoidable application of coun-
ter-irritants to destroy the lameness but in
the latter they seem to disagree to a great
extent, individually each one claiming an adj
vantage for his treatment over all others.
Some deem repeated blisters as sufficient.
and leave a comparatively slight blemish.
"Others Introduce a seton and thereby
keep up an incessant counter irritation, and
from this also but little blemish accruses.
Farmers and. quacks can even at this day be
found who resort to the application of ac-
IDS, and their success is generally character
lZed by the destruction of the entire limb.
But we find a number who most sensiblv
consider a still severer c~ounterirritant nee
essary, and with repeated success use the
actual cautery, and consider it a serious
mistake on the part of those who try to dis
it's use In this respect. What we
wish to produce by counter-irritation in the
spawn, is an increased effuslon oflymph by
exciting extreme Inflammation, and as the
effilsed lymph is quickly converted into
bone, and a complete union of the joint eff
lected, the sooner this is accomplished, the
sooner IS the lameness removed; and the
