Veterinary obstetrics, including the diseases of breeding animals and of the new-born . oom. If the pelvis of thefetus is too small to admit the hand of the operator at all beforesevering the sciatic ligament, this may be accomplished by cau-tiously cutting from behind forward with Colins scalpel or withthe chisel. When this has been severed and sufficient operating room, at-tained, carry the chisel in the hand and place it against the shaftof the ilium, as shown between I and I, as nearly perpendicularto the long axis of the iliac shaft as possible. Keeping the handin touch with the chisel blade, have an assistant drive it throughthe bone until it and its periosteum are completely rotate the chisel upon its long axis, in order to completethe division of the bone and attached soft parts. Disengage thechisel, and then place it against the symphysis pubis or 654 Veterinary Obstetrics against the ischium opposite the foramen ovale, and driveit through the ischium and pubis at one of these points. Againrevolve the chisel upon its long axis and, using it as a. lever, separate the isolated portion of the pelvis as com-pletely as practicable from the surrounding tissues. With thefingers, aided by the chisel if necessary, detach the muscles from E?nbryoto?ny. 655 the isolated segment of the pelvic girdle for a short distancefrom each severed end. Attach a strong looped cord about the de-tached pelvic segment, and tighten the noose. Have one or moreassistants apply traction as indicated in Fig. 111 B. The chiefobstacle to the withdrawal of the limb is the great gluteus muscle,which should be sought for, identified, and torn through with thefingers at a distance of 5 or 6 cm. from its attachment to thegreat trochanter of the femur. This is best done while steady,firm traction is being applied to the limb by an assistant, thustensing the muscle. Other important points of resistance are the attachments, pos-teriorly, of the skin, vulva and anus to the ischium t
