wards towards the middle line, the artery lies close to the
inner side of the bone. It is divided into common, super-
ficial and deep femorals. The common femoral begins,
above, immediately beneath Poupart’s ligament, and ends
where the other two begin, generally about one and a half
inches below Poupart’s ligament. elations.—lIt lies in
Scarpa’s triangle, having the integument, the superficial
and deep fasciz, transversalis fascia, the crural branch of
the genito-crural nerve, and the superficial circumflex
iliac vein, in front; behind, it rests on the psoas tendon,
which separates it from the brim of the pelvis and the cap-

sule of the hip joint; lower down, it rests on the pectineus
muscle, being separated from it by some fatty tissue. In-
side, is the femoral vein, and outside, is the anterior crural
nerve. The superficial femoral is superficial, only, while
contained in Scarpa’s triangle, since, below this, it is
covered by the sartorius. It has, in front of it, the integu-
ment, superficial and deep fascize, and a branch of the in-
ternal cutaneous nerve crossing it near the apex of the tri-
angle. Behind, it has the pectineus, being separated, near
the lower end of Scarpa’s triangle, fromthe muscle, by the
following structures in the order named: Femoral vein,
profunda vein and profunda artery. Lower down, it lies on
the upper part of the adductor longus muscle. On the outer
side, is the long saphenous nerve and the nerve to the
vastus internus. Inside, is the -femoral vein, above,
although, as the apex of the triangle is approached, this
vein gradually gets behind the artery. This portion of
the superficial femoral is about three and a half inches in
length, while the rest of the vessel, viz., that contained in
Hunter’s canal, is about five inches long. Hunter's canal
is a triangular-shaped space bounded by the vastus inter-
nus, externally, the adductor longus and magnus, internal-
ly, while, in front, is an aponeurosis, which stretches across
from these boundaries and consists of transverse fibres
especially marked over the lower part of the canal. The
artery has in front of it, in this situation, the integument,
superficial and deep fasciz, the sartorius, the aponeurotic
covering of the canal and the long saphenous nerve lying
in front and to its outer side.
