This historic 1920 paper by Bradley Patten described the understanding of chicken development. If like me you are interested in development, then these historic embryology textbooks are fascinating in the detail and interpretation of embryology at that given point in time. As with all historic texts, terminology and developmental descriptions may differ from our current understanding. There may also be errors in transcription or interpretation from the original text. Currently only the text has been made available online, figures will be added at a later date. My thanks to the Internet Archive for making the original scanned book available.

Contents • • • • • • • • Introduction Historically, an important way of teaching embryology is by direct observation of histological sections at different stages of development. Even today the best way to observe anatomical development and relationships is by direct observation in serial sections through the embryo and fetus. The sections below are from the original teaching set prepared at UNSW that were digitized and put online in 1996 as a teaching resource. The Stage 13 and 22 images are available in at least two formats, an unlabeled set (image 1 - 49) and a labeled set (image 50 - 98) in a rostro-caudal sequence (head to tail). Stage 22 embryo also has a set of selected images showing more detail of some organ and tissue development. In addition, there are now 3D animations based upon reconstruction of the embryos from these serial sections. 2011 - Selected slides are currently being rescanned at to show specific developmental details.
Author Comments Start here by looking through the early (week 4) embryo (stage 13) labeled images. It is not so important to identify every single feature, observe what structures are present and where they are in the middle of the embryonic period (week 4). Then if you like, look through the unlabeled images. What can you now recognise? Next look through the late (week 8) embryo (stage 22) labeled images as you did before. Then look through the same embryo stage selected labeled images.
