Book excerpt: Excerpt from An Introduction to the Study of the Comparative Anatomy of Animals, Vol. 2 The publication of this volume has been long delayitf^^ing to my having been on military duty throughout the year 1900. As in the first volume, I have been guided in my selection of types of animal organisation by the requirements of students reading for the preliminary and intermediate science examinations in the Universities of Great Britain. A considerable space has been allotted to the leading features of the embryology of the various types, since, as I believe, a just appreciation of the problems of Comparative Anatomy cannot be attained without the study of embryonic as well as adult structures. The second volume has been finished under more favourable circumstances than the first, and I hope that it will be found to be free from any serious errors. In the first volume, besides some slips of minor importance, I made a serious error in my description and figure of the truncus arteriosus of the Frog. This was not because, as a friendly critic has suggested, I drew my figure from an abnormal specimen, but because I attempted, when in barracks, to construct my figure and description from the rough drawings of my preparations, and got into confusion in the attempt. A new figure, with the necessary corrections of the text, will be found in the errata attached to this volume. A full and, at last, an intelligible account of the structure of the truncus and the function of the spiral valve is given in the new edition of Ecker & Wiedersheim's " Anatomie des Frosches," by E. Gaupp, 1899, pp. 260 and 283. I have to express my obligations to Mr O. H. Latter, M.A., of Charterhouse School, who has kindly read through the proof sheets of this volume and assisted me with many valuable criticisms and suggestions, and to Mr J. W. Jenkinson, M.A., of Exeter College, Oxford, who has helped me in many ways, particularly in placing at my disposal his wide and exact knowledge of the placentation of the Mammalia.
