A, middle of cctoplacental cone; B, ectoplacental end of the proamniotic cavity; C, just above level of junction of the primary embryonic and extraembryonic ectoderm; a little above the middle of primary embryonic ectoderm. The want of any definite bilateral sjinmetry of albino rat egg-cylinders of this stage of development is shown by this series of sections; , parietal or transitorj^ ectoderm; , extraembryonic ectoderm, surrounding mesometrial portion of proamniotic cav- ity; p?;., primary embrj-onic ectoderm; »/., visceral entoderm; ent., primary embryonic entoderm; , proamniotic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Huber, Gotthelf Carl, 1865-.
