The Amphioxus: And Its Development is a scientific book written by Berthold Hatschek in 1893. The book is a detailed study of the amphioxus, a small, fish-like creature that is considered to be a primitive ancestor of the vertebrates. The author provides a comprehensive overview of the morphology, anatomy, and embryology of the amphioxus, as well as its life cycle and behavior. The book is divided into several chapters, each focusing on a specific aspect of the amphioxus. Hatschek's work is notable for its detailed illustrations and descriptions of the amphioxus, which were based on extensive research and observation. The book is considered to be a classic in the field of zoology and is still widely cited by researchers today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
