Fig. 205. Three-germ-layered blastoderm or late gastrula of chick, showing the mosaic distribution of developmental tendencies. (AC after Rawles, '36; D and E after Rudnick, '44, from various sources.) (A-C) The lines transversely placed across embryo are at levels of 0.3 mm. and 0.7 mm. from the center one, considered as 0.0 mm. (A) Ecto- dermal or external layer: neural plate area is indicated in black, epidermal area in white. (B) Mesodermal or middle germ layer. (C) Entodermal or inner germ layer. (D) Ectodermal layer shown on left, mesodermal and entodermal on right. (E) Superficial or ectodermal layer shown at left, deeper layer, at right. (Note: These diagrams should be considered only in a suggestive way; final knowledge relative to exact limits of poten- cies, especially in the mesodermal layer, should be more thoroughly explored.)
