    from the iliac fossa, till the junction of the cervix and vagina is reached. An opening is then made into the vagina, and the os is dilated; the child is then extracted through the vaginal wound and out through the abdominal opening. Symphysiotomy. Division of the symphysis pubis was formerly practised, with a view to widening the pelvic canal, and allowing the passage of the foetus in cases where Csesarian section would otherwise have been necessary. The conjugate diameter is very little increased by division of the symphysis, hence the operation has fallen into disuse. XLVI.—ANAESTHESIA IN LABOUE. During the first stage of labour anaesthetics should be avoided, as they tend to weaken uterine contractions ; in cases, however, where the cervix is rigid and great pain occurs during its dilata- tion, chloral is often of service. Chloral, like chloroform, lessens the pain, but unlike chloroform, it does not enfeeble the action of the uterus. In the second stage chloroform is of great use in lessening the suffering, and it should be given during the pains, not, however, to complete anaesthesia. During the intervals it should not be administered. Chloroform predisposes to post-partum haemor- rhage, hence during and after the third stage it is necessary to guard against it by securing efficient contraction of the uterus. During the third stage of labour chloroform should not be given. In obstetric operations, when it is decided to give chloroform, complete insensibility and relaxation should be produced by administering it to its full extent. XLVIL—TEANSFUSION OF BLOOD. Indications.—Transfusion is indicated in cases of extreme collapse following post or ante-partum haemorrhage. Its object is chiefly to stimulate the heart of the patient to
