Emil Selenka on the embryonic membranes of the mouse and placentation in gibbons and orangutans

Selenka's work was thorough and brilliantly illustrated. It was an important influence on his contemporaries and was well known to scientists of the following generation. Embryologists continue to advance our knowledge of fetal membranes and placentation in the mouse, but Selenka's work on gibbons is unique and our knowledge of orangutan placentation is restricted to his specimens.
