EXPLANATION OF FIGURES
46. A vesicle cut open along the mid-ventral line to show the relationship of
t he embryos to each other and to the wall of the vesicle. Each of the four amniotic
partitions (a), which have been cut off close to the chorionic wall, lies just to the
left of the umbilical cord. These are attached to the wall near the tips of the
placental lobes at the fundus end. The left lateral placental disc is indistinctly
seen thiough the chorionic wall, and the notch separating it from the right
lateral disc is marked with the larger “n”, while that indicating its division into
the two lobes is designated by the smaller “n,” X |.
47. A photograph of vesicle no. 108, which contained five embryos. This
vesicle was cut open along the mid-ventral line. Embryos nos. I, II, and II, are
attached to the large, right lateral placental disc, and embryos III and IV to the
smaller, left lateral. (See text for a fuller description and significance.) X \.
