Various Glasses Of corns and Some Of
the Causes Which Produce Them
Meeting Of the Horseshoers Held
Wednesday Evening.

About fifteen Of the ,horseshoers OF
the city have formed a class for the
purpose Of studying the shoeing of
horses from a scientific standpoint,
IT Is the beginning of a movement in
Iowa which the promoters hone NAV
assume such proportions that the leg
islature may eventually be induced to
require all men engaged iii the shoeing
OF horses to have a certificate which
may be obtained only after passing
an examination as to proficiency. The
nrst meeting vas an enthusiastic one
and n Of the features was a paper
regarding corns on horses feet, by
Charles Aldridge. The paper was as
follows:
"Corns.-Under this name is under.
stood an alteration Of the tissues un-
underneath, viz: in the keraphyllous
horses foot by LESSONS of the living
parts in the movements of expansion
of the hoof; by bruises, compress.
sion or commissions. There Is then a
capillary hemorrhage which extends
in the heel of the hoof.
"a corn then is a bruise of the liy-
ing horn at the extreme end of the
braces of the sole, and especially in
the Illuminated tissue Of the folds of
the bars. 1t is a very common disease
and one to which all horses are ex-
posed. Some have them constantly.
Corns are found mostly in the fore
feet, and on the inside more common
ly than on the external side. They
are rare on the hind feet because in
the various gaits the weight of the
body is carried more on the front legs
and on the %posterior part of the foot
while in the hind legs it is the front
part which principally receives 1t.
"Divisions.-La Posses, ST., has dis
tinguished them into natural and ac.
cidental-while Girard considers them
all as accidental. III. Baulay desig-
mates as essential those which come
from other than external causes. We
believe that it would be better to es.
tablish the divisions on pathological
and anatomical bases, and admit a
corn of the wall or laminated. That
which has its seat in the laminae
which unites the wall to the tissues
underneath, viz: in the heraphyllous
and phodophyllous tissues of the heels
and bars, that is a rupture of the blood
vessel, and a corn of the sole or vel
vety, that which has it's seat in the
velyety tissues which unite the sole
to the fieshy parts. The laminated
corn corresponds exactly to the natur-
al of La Posses, and to the essential
of Bouley. 1t is due to decorations in
the movements of expansion of. a
badly made foot. The other is due
to Commissions.
whatever may be the adopted d.
visions we with Girard, and as admit
ed in practice, recognize in each cate
CORY the dry, the moist and the sup
purated corns. All feet are exposed,
but not all predisposed to corns. They
are more frequent in heavy feet with
those where the heels are high or con-
tracted in which there is a motion of
retraction of the hoof which interferes
with the displacement backward of
the third phalanx at the time Of rest;
and hence the decorations are easy.
Besides there is a continual pressure
upon the living parts Of the posterior
regions of the nails.
"Corns are frequently observed In
excessively long feet. where the hoef
does not receive the moisture neces.
sary to its elasticity. 1t then loses it's
suppleness and fails to assist the in
ternal motion of the parts contained
within.
ut is seen whene e- the hoof is
too dry, the posterior iameter of the
feet being then diminished Corns are
seen on weak feet on which the foot
is too thin to resist the dilating effects
