The placenta may be adherent as the result of syphil-itic or other inflammation of the endometrium during pregnancy,and, becoming partially detached in the third stage, may causelemorrhage. It is very commonly simply retained in.

Insome cases the atmospheric pressure obstructs the delivery of aretained placenta so effectually that it is necessary to hook onesfinger over the edge of it, to allow the access ol air behind it, before its expression is possible. Retention of the placenta maybe due to its great bulk, as in twin placentae, or to tumorsincreasing its size. In such eases it may be necessary to extractthe placenta manually.
