Excerpt from Text-Book of the Embryology of Man and Mammals The history of the development of the individual, or Ontogeny (embryology), is the science of the growth of an organism 5 it de scribes the morphological changes which an organism passes through from its origin in the ovum up to its complete maturity, and presents these in their natural connection. We can regard the fertilisation of the egg-cell as the beginning of the process of development for Vertebrates, as it also is for all the rest of the higher animals. In giving an account of the changes of the egg-cell, which begin with fertilisation, one may choose between two different methods. According to one method a particular organism is made the basis of the account, and one describes the changes which its germ under goes from the moment of fertilisation onward, from hour to hour, and from day to day. It is in this way that the embryology of the Chick has been worked out by C. E. Von baer in his classical paper, and by foster and balfour in their Elements of Embryology. This method has the advantage that the reader acquires a View of the total condition of an organism in the separate stages of its development. A book of that kind is especially suitable for such persons as desire to acquaint themselves, by their own observation, with the embryology Of a single animal, as, for example, the Chick, by repeating the investigations of others. It is, on the contrary, less adapted to those who wish to acquire a connected view of the development of the separate organs, as the eye, the heart, the brain, etc. For the formation of these will of course be treated of at different places in describing younger and Older embryos. In order to procure a general survey of the course of development of an organ, the reader must consult various places in the text-book, and collect for himself what relates to the subject.

Excerpt from Text-Book of the Embryology of Man and Mammals The rapidly increasing recognition of the importance of Embryology in all morphological studies makes it desirable that the most valuable text-books upon tho subject, in whatever language, be made available for those who are beginning its study. Although tho English-reading student already has at command a number of text-books upon this subject, it is evident to any one familiar with Hertwig's Lehrbuch der Enlwicklungegeschichlt des Menschen und der Wirbeltkiere that this work covers the field of Vertebrate Embryology in a more complete and satisfactory way than any book heretofore published in English. Two important objects to be accomplished in a text-book are: first, a clear and methodical exposition of the well-established facts of the science; and, secondly, such a presentation of unsettled questions as shall stimulate tho reader to further inquiry and research. I believe it is far too common for the second of these aims to be overlooked. Tho present work fulfills both requirements in an eminent degree, and in its historical surveys exhibits an exceptional fairness of treatment, notwithstanding tho author has been one of the foremost contestants in several of the fields reviewed. Tho summaries which follow the discussions of the several topics serve a useful purpose in directing attention to the more important conclusions drawn from each subject. I have aimed to give a clear and accurate reproduction of the author's ideas; while I have endeavored-not always successfully- to avoid awkward renderings and German idioms, I have preferred to err on tho side of a too literal rather than a too liberal translation. There are a few points that demand a brief explanation. The German word Anlage has heretofore been variously rendered into English by rudiment, origin, beginning, basis, foundation, etc., while some writers, recognising tho inadequacy of any of these words to express the idea, have incorporated tho German word itself in their English.
