ANATOMY OF THE HORSE. 
Relations . —On the outer side, with the psoas magnu.s, vastus 
internus and gracilis; on the inner, with the faschia lata and 
skin. Along its posterior and outer border run branches of the 
femoral bloodvessels. 
Structure. — Fleshy and rather pale; except the extremities, 
which are aponeurotic. Its anterior aponeurotic end is so in¬ 
timately united with the psoas parvus, as it runs forward side 
b y side with it, that it is somewhat difficult to make out the 
distinct lumbar attachments. The inferior termination consists 
of a broad, flat, glistening tendon, which (in union with the 
tendon of the gracilis) expands into an aponeurosis, spread¬ 
ing over the entire inner side of the stifle joint. 
Action , —To assist in bending the leg; and, in the flexed po¬ 
sition, to give it a rotatory motion inwards. 
gracilis.— Sub-pubio-tibialis . 
Situation. —Superficial, on the internal part of the thigh. 
Figure. —Quadrilateral, broad, thin, flattened. 
Attachment. —Superiorly, to the symphysis pubis, extending 
as low down as the ischium; inferiorly, (along with the sar- 
torius) to the supero-internal part of the tibia, and the internal 
condyle of the femoral bone. 
Relations .—Along its antero-internal border, with the pec- 
tineus and sartorius; on its inner side, with the adductors; on 
its outer side, with the faschia lata and skin. 
Structure. —The pubal attachment is tendinous and fleshy: 
inferiorly, it ends in a broad aponeurosis, which, forming a union 
with the tendon of the sartorius, expands upon the inner side 
of the stifle, and is continued upon the leg into the tibial 
faschia. 
Action. —To bend the leg, and (when flexed) to rotate it 
inwards. 
pectineus.— Super-pubio-femoralis. 
Situation .—Inner, upper, and anterior part of the haunch. 
Form. —Fusiform; thickest in the middle; upper extremity 
flattened. 
Attachment .— Superiorly, to the brim and anterior surface of 
the pubes, near the symphysis; and to the infero-anterior part 
of the same bone, near the acetabulum. Inferiorly, to a long 
Tidge extending from the trochanter internus. 
Relations . —On the outer side, with the sartorius; anteriorly 
and internally, with the gracilis; posteriorly, with the ad¬ 
ductors. 
Structure. —The superior attachment consists of a stout bifur-
