    (1) In some cases of placenta 2mevia, and of accidental hcemorrhage. Operation facilitated by first dilating tlxe cervix. (2) In some cases of urincemic convulsions. Chloroform or nitrite of amy], dilatation of cei-vix and bi-polar turning. (3) In some cases in which lahou7- has been frovohcd before term on account of contraction of pelvis, bi-polar turning preferable to forceps. Dangers to mother and child from turning.—(See note on Statistics under Forceps.) To the mother.—1. In cases from disproportion, in which bi-polar turning can be efifected without difficulty, danger is small. 2. Danger lises when liquor amnii has escaped, and persistent contraction of uterus has set in. 3. Still higher, if in addition, marked contraction of pelvis, or head large and not plastic. In the latter case force in passing hand may rupture the uterus. i. Protracted pressure may result in sloughing; exhaustion. To the child.—The risk is serious :—1. From compression of the cord. 2. From dragging in extraction before cervix i.s dilated. 3. From dragging in a vicious dii-ection so that passage of head is delayed; and 4. Excessive traction made on its tieck. If the child has been some time dead, the pelvis being contracted or not, the neck may give way, and the head be left in uterus. 5. From rotating the child on its long axis to ' give the turns,' the neck may be twisted. 6. From compression of brain in forcible dragging through narrow conjugate. The proximate parietal bone may be broken in. 7. From liquor amnii being spent, direct pressure upon placenta between cliild's head and the uterus. 8. From unintermittent uterine con- traction utero-placental circulation is arrested. In breech cases.—Operations analogous to version sometimes required :—1. Breech-wedging in pelvis, legs flexed. A foot is
