The works of Francis Maitland Balfour, Volume 3 (of 4) : $b A treatise on comparative embryology: Vertebrata

"The Works of Francis Maitland Balfour, Volume 3" by Francis M. (Francis Maitland) Balfour, is a deep dive into the world of embryos, specifically exploring how creatures called Chordata, including Vertebrata, grow and change from tiny beginnings. Balfour's work takes us through the steps of how different body parts and systems form, like the nervous system and the notochord, using examples like Amphioxus to explain important processes such as segmentation and invagination. It lays out the groundwork for grasping how creatures, from the simple Cephalochorda to more complex vertebrates, develop from organized layers in their early stages.
