Text-Fig. 4. M‘Intyre embryo

Photomicrograph by Professor J. H. TEACHER of a section of the body-stalk. The prolongation of the amnion also appears, and is seen passing off from the dorsal aspect. The allantoic duct can be recognised about the centre of the stalk. On either side of it an umbilical artery is present; behind it on one side a venous space is seen and on the other side an angioblastic mass (the dark elongated area). In the mesoderm of the amnion wall the “blisters” referred to in the text are shown.

x 120. Section No. 154. See text-fig. 2.
