Abstract
IT is now twenty years since Prof. Hubrecht published, in the pages of the Quarterly Journal of Microscopical Science, his classic researches on the trophoblast and allantoic placenta of the hedgehog, Erinaceus europaeus. This work, along with the investigations of. Eduard van Beneden and M. Duval, may be said to have revolutionised our knowledge of the placental phenomena in the mammalia. By it new light was thrown on the egg-cleavage, the so-called gastrulation, and, especially, on the mode of origin and the nature of the “fœtal membranes,” the chorion (trophoblast), amnion, and allantoic placenta. For the Dutch investigator this was the starting-point of a long period of painstaking researches into the placental conditions of diverse mammals, and of these the present work is an author's translation of the English version, published (November, 1908) in the journal containing his earlier results.
