Twelve Lectures On Comparative Embryology (1849) - Louis Agassiz

Twelve Lectures on Comparative Embryology is a book written by Louis Agassiz, a Swiss-American biologist and geologist, in 1849. The book is a collection of twelve lectures that Agassiz delivered at the Lowell Institute in Boston, Massachusetts, in 1848. The lectures explore the topic of embryology, which is the study of the development of embryos from fertilization to birth. Agassiz compares the embryonic development of different species of animals, including fish, reptiles, birds, and mammals. He discusses the similarities and differences in their development, as well as the evolutionary implications of these differences.The book is divided into twelve chapters, each of which covers a different aspect of embryology. Agassiz begins by discussing the history of embryology and the various theories that have been proposed to explain embryonic development. He then goes on to discuss the early stages of development, including fertilization, cleavage, and gastrulation.In later chapters, Agassiz focuses on specific groups of animals, such as fish and reptiles, and compares their embryonic development to that of other groups. He also discusses the role of the environment in embryonic development, and how different environmental factors can affect the development of embryos.Overall, Twelve Lectures on Comparative Embryology is a comprehensive and detailed exploration of the topic of embryology. It is a valuable resource for anyone interested in the field of biology, evolution, or animal development.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
