POrrsvILLE, June 16 The June meeting
of the Schuylkill Valley Veterinary Medical
Association was held here this morning and
well attended. All parts Of the county were
represented and the meeting was one OF the
most interesting the association has ever
held. After the transaction Of routine busi-
ness DR.. Potteiger read paper ON pneumonia
and Dr. W. II. Yingst, of Shenandoah, read
one on pathological shoeing. Discussions and
reports of some interesting cases followed
The paper read by DR.. Yingst was as follows:
The subject of my paper, pathological
shoeing, is one that has attracted great deal
of attention aud especially Of late years.
This, of all subjects has met with a great
variance of opinions. 1t is a subject Of such
a nature that If one is interested in it, he Will
find that each day will add TO his knowledge,
and there is no saying how long a man can
study and practice before becoming expert
enough TO Immediately, by looking at
horses foot, know what sort of a shoe to
apply to correct a certain fault. But l be-
lieve by application and Observance man
can acquhe that faculty which means that
the same faults in different horses cannot all
be corrected by certain method. The horny
box contains the lower portion of second
phalanx, third phaanX aud navcular bones,
lateral eastciibro cartilages, having for a
covering a vascular netw ork allowing but
hexor tendons resting on an elastic cushion,
and enveloped IN dense keratogenous box,

besides the bones, in front. are observed
anterior eXtensor of the phalanges, on sides,
the anterior lateral lgiments and posterior
lateral ligiments. The lateral cartilages
occupy space between the pOsteriOr border of
anterior lateral ligiments, and anterior
border, of pOstoror lateral ligiments
The perforans tendon behind, reaches the
navicular bone and spreads into q wide
kentogenous or horn growing) membrane.
The planter cushion is a iihro-iatty mass,
shape like frog, and lies against posterior
portion Of phalanX, and corresponds to faces
of lateral cartilages and is continuous with
their fiTOus capsule; inferior surface res's on
superior face Of frog. 1t is dense aud elastic.
The horny box comprises the wall and sole.
