_ Technic. Prior to attempting the operation, it is well
to make a rectal exploration and determine as far as may
be, the location of the testicle, whether it be on the right
or left side, and its character, should it be in any way
pathologic. Confine the animal by casting in the dorsal
position with the hocks well flexed and both posterior
limbs completely abducted so as to fully expose the inguinal
region. Or secure upon the operating table on the side
opposite to the retained gland and abduct -the upper poste-
rior limb by drawing it upward by means of a pulley.
Cleanse and disinfect the inguinal region. Anaesthetize.
Make an incision about ro to 12 cm. long through the skin
and dartos directly over the normal position of the scrotum,
parallel to the median raphe and about 4 or 5 cm. distant from
it. Insert the two index fingers in the wound, press them
into the areolar tissue toward the external inguinal ring
and drawing them apart, separate the tissues sufficiently to.
permit the entrance of the hand. into the inguinal space.
With the fingers held in the shape of a cone, bore a passage
in the areolar tissue through the external abdominal ring
and continue in a direction approximately toward the ex-
ternal angle of the ilium until the aponeurosis of the small
oblique muscle near the crural arch is reached. Unless.
rectal exploration has shown that the testicle is within the
abdomen, take care in traversing the inguinal space between.
the external and internal rings that the gland is not passed
by unrecognized (inguinal cryptorchidy), lying in this re-
gion covered by peritoneum and the cremasteric fascia.
