A theoretical and practical treatise on midwifery : including the diseases of pregnancy and parturition and the attentions required by the child from birth to the period of weaning . Fig. 53. The internal, or foetal surface of the 54. The external, or uterine surface of the placenta. so that after its expulsion, the cotyledons appear to be separated from each otherby deep furrows or fissures. The external surface of the placenta is covered by the decidua, or inter-utero-placental mucous membrane \ a true maternal placenta, which is thrown off inconnection with the fetal placenta (see Structure of the Placenta), and whichcovers the convex surface of the cotyledons to the depth of about one-eighth ofan inch. This maternal placenta is traversed by numerous vessels, the openorifices of which are seen upon the external surface of the after-birth (utero-placental vessels). The placental circumference is thin and irregular, and its extent, althoughvery variable, is generally about twenty-five inches. The margin, according toM.
