This fascinating essay by David Low explores in detail what divides members of the animal kingdom, as well as the concept of "external form". Low looks at history, geography, biology, and natural history in an adventurous attempt to better understand our animal counterparts. "Divisions of the Animal Kingdom and Properties of External Form" is highly recommended for those with an interest in animal biology, and it would make for a fantastic addition to collections of related literature. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in a modern, high-quality edition complete with the original text and artwork.
