In a brief historical survey, the importance of Wilhelm His, senior, to human embryology is emphasized. He provided the impetus to Mall to establish the Carnegie Embryological Collection, which serves as a 'Bureau of Standards' for early human development. The Carnegie system of 23 stages for the embryonic period proper (first 8 postovulatory wk) is outlined, and some common misusages are noted. Finally, because of the difficulty in tracking down data based on staged human embryos, an annotated list of more than 40 key references is provided.
在一个简短的历史概述中，强调了老威廉·希斯对人类胚胎学的重要性。他推动了马尔建立卡内基胚胎学收藏馆，该收藏馆作为早期人类发育的“标准局”。文中概述了适用于胚胎期（排卵后前8周）的23个阶段的卡内基系统，并指出了一些常见的误用情况。最后，由于基于分期人类胚胎的数据难以查找，提供了一份40多篇关键参考文献的注释清单。
