    Lee. These gentlemen deny that any connection exists between the uterus and placenta, except, perhaps, by small nutrient vessels. Later still. Dr. H. Ley* has had an opportunity of accurately examining a gravid uterus, and he corroborates the account of Hunter, which is also supported by the testimony of Professor Burns. As yet, I think, we must consider the question as unsettled, al- though probabilities certainly appear to be against the notion that any very large vessels pass di- rectly between the two parts. The internal, or foetal, surface of the placenta is not, like the other, divided into lobes, nor has it the same spongy, glandular appearance, but is formed of an immense congeries of vessels, together with cellular sub- stance and a number of white filaments, the na- ture of which does not appear to be understood: it is covered by a thin layer of decidua, which is very intimately connected to it; and by the chorion and amnion. The internal structure of the placenta has been the subject of much dispute. It can be injected freely from the vessels of the cord ; and it was sup- posed by William Hunter that injections could also be thrown from the uterine vessels into cells in its substance. From these circumstances, and from the fact of distinct uterine and foetal portions ac- tually existing in the placenta of many animals. * Med. Gaz., vol. xii.
