coidal thickening of the animal pole of the egg, to which the subsequent cleavage
will be restricted' (Figs. 9/1-9/6). 'Vogt (1842)' described that the 'Keim' (germ) of ...

Early Embryology of the Chick, Fourth Edition
The central portion of the blastodisc is surrounded by a somewhat darker
appearing marginal area known as the periblast. The protoplasm of the
blastodisc, especially in the periblast region, blends into the underlying white
yolk so that it is ...

Daedalus: Journal of the American Academy of Arts and Sciences
At every clearing up we observe that the blastodisc is increasing in size, while the
periblast becomes thinner and thinner. There can be no doubt about the fact that
the blastodisc actually draws the larger portion of the periblast into itself during ...

These smaller vacuoles surround the germinal vesicle (g. v.) symmetrically on all
sides, except where it adjoins the peripheral protoplasm and from this area the
blastodisc is differentiated. The same conditions may be observed in figure 27 in

Pamphlets on Biology: Kofoid collection
A study of meridional sections of many eggs in this stage shows that the
blastodisc takes on different forms. In most eggs it is distinctly crescentic, but in
some it is lenticular. When it takes on the crescentic form, as shown in Fig. 21,
there is ...
