Plate 4, fig. 4. Teacher-Bryce Ovum No. 2

Photomicrograph of Section 28.2.2 for comparison with the drawing. This section passes through the centre of the operculum. Only the yolksac appears in it.

Note the tearing of the blastocyst wall from the blood of the intervillous space close to the operculum, the coaguluin and its situation at the dependent aspect of the blastocyst (dorsal decubitus of body) and the large venous sinus below the ovum.
