Professor Lang has here successfully carried out the very difficult task of selecting the most important results from the bewildering mass of new material afforded by the extensive researches of the last decades, and of combining them with great judgment. Besides this he has, more than any former writer, utilized the comparative history of development in explaining the structure of the animal body, and has endeavored always to give the phylogenetic significance of ontogenetic facts.—From Professor Haeckel’s Preface.
