rNaylcular Arthritis.

Prof. Greasy said that in the foot of {
horse we have three bones and three
joints. The bones of the pedal, or coffiI
bone; the navicular, or shuttle bone
and the coronet, or lower pastern. The
joints are first the coffin joint, or join
ing of the pedal and the coronet bones
next the llaviculo-pedal, joining thu
shuttle and pedal bones, and the navi
eulo-coronet, joining the shuttle and co
rotiet bones. ! In Founder, the hors,

In navicular arthritis the horse step
short and on his toes, like man who
is groggy, and the name has come t.
be very generally adopted, some of the
best Scotch authorities so naming it
This disease may be induced by out
ward injury, as by stepping on angular
stones, as in roads paved with trar
rock, when a point of stone may bt
driven between the frog and the hoof
giving direct injury to The large liga
ment, causing inflammation, exndatiol
and suppuration, which, remaining {
long time, works down through The
bottom of the foot, giving a diseased
condition, which may result in thrush
and this, after long standing, may be
come fistula. In describing this, the
lecturer remarked that tho frog is about
half as hard as the sole and the sole
about half as hard as the hoof.
Such cases as these cannot be cured
by applying some wash or little oint.
ment, or by the treatment of some
quack who promises that the trouble
can be cured in twenty-four hours. II
is necessary to apply the knife, making
a clean, clear opening into the cavity
where the injury had its origin, and
then a solution of carbolic acid, made
by dissolying the crystals, should be
thrownup into The sore by asyringe
This can be done when The foot is down
by having the nose of the syringe
slightly crooked.
Sometimes the sore appears back OF
and above the hoof; in such cases it is
not u primary disease, but trouble re.
sulting from either iaminitus or navicu.
lar arthritis.
! Horses having tender spongy feet
and straight. pastern are more liable to
this last disease. A hard, well-round.
ed foot, with an obliquc pastern, will
rarely show this trouble, except from
some mechanical injury, the oblique
pastern nccessiating a strong tendon fol
its support, and thus affording q better
profession to the shuttle bone = 40
This discsse may also be in some
measure Hereditary, induced by breed
ing from horses in an unhealthy con.
dition. One English veterinarian gives
an instance where all three of these
joints were entirely joined. These dis
eases -laminitis, or founder, and navi.
cular arthritis, or naviculitus-may be
aileviated by a rnode,of shoeing which
would give relief to the inflamed parts
and aid the cure. The foot should be
shod with a shoe having calks of equal
height all around. In shooting a foun-
dcred horse the toe should be raised
high by toe calk and there should be
no heel calks. In shooinR for navicular
rthris the heels should b high with no
toe calk. I'm these cases hree-fourths
of an inch is not too much difference to
make between the heighth of the heel
and toe From lecture at the YER
