Carnegie No. 8905, Merrill. Unbranched villi. Although an abnormal leucocytic reaction is present, this specimen “represents the best example in the author’s collection of formation of early primordial villi, active mesogenesis and angiogenesis, completion of the amnion and the transitional phase between the primary and definitive [secondary] yolk sac formation” (Hertig, 1968, who reproduced a photomicrograph as fig. 55). Presumed age, 12-13 days.
