Text Fig. 3. Teacher-Bryce Ovum No. 1. Surface plan of the lobule of decidua reconstructed from the sections

X 20. The spaces between the lines represent the total thickness of the sections on each slide with the extra sections from the “ series at intervals” preparation added. Gl. 1, 2, 3, 4. Mouths of glands in close relationship to the implantation cavity. The straight lines and splay mouths indicate that the glands have been stretched over the growing ovum. The faint lines passing from Gl. 1 to Gl. 2 indicate a shallow groove. The light circle near Gl. 1 shows the position and size of the aperture of entrance. The heavily outlined pearshaped area represents the blastocyst enclosing the two vesicles also heavily outlined. The oval one is arnnio-embryonic. Drawn to scale by J. H. T.
