WARD CUTLER, D.Sc., M.A., Chief Protozoologist to the Rothamsted Experi- mental Station. With a bibliography and many diagrams. (Christophers, London). Designed primarily for the use of students, this survey of the fundamental facts of Biology will be of considerable interest to a wide general public, since it will serve as an introduction to the subject which underlies the approach to all the problems of Sociological investigation. The book,presents without bias and in a clear form the conclusions arrived at by twentieth century science on this subject of universal concern. 4s. 6d. net; a cheaper edition, for use in schools 3s. 6d.

His insistence on effort and character is of the utmost value in these supine days, and the book is well fitted for parents to put into the hands of adolescent sons. The author has not shirked the sex difficulty and devotes a chapter to it full of excellent advice to the growing youth; though those who have given attention to this difficult subject will hardly find it sufficient for those enter- ing on manhood. Nor will the evolutionist quite assent to the author's views on -the universe. Nevertheless "Rovering to Success" is a welcome relief from the nauseating literature of our day which insists on rights and an easy existence with- out effort or social obligation. C.V.D.

THIS book is intended to present in a simple manner some of the results of modern research in the great questions of evolution, heredity, and variation. It is also hoped that it will be useful to pupils in the higher forms of secondary schools. In attempting to compress so much matter into such a small book the author has set himself a difficult task. We consider that he has achieved a considerable degree of success and that his book will be read with interest and profit by unscien- tific people who have a thirst for knowledge. The first two chapters, devoted to the evidence for evolution, are followed by two which give an interesting account of the history of evolutionary ideas from the time of the Greeks. Succeeding chapters devoted to Mendelism and recent cytology in their bearing on evolution form perhaps the best part of the book. The concluding chapters deal with bio- metrics, and variation. The writer speaks with the assurance of the expert, yet expresses himself sufficiently simply to be, on the whole, within the comprehension of intelligent young people of sixteen or seventeen who are studying biology under a competent teacher. At the same time, the book is not so good but that it might be better, and a few words of criticism must be offered, with the hope that these may be of service to the author if a revised edition should be called for. The author's style is somewhat colourless for a popular book, some of his sen- tences are ambiguous, and several errors have escaped correction. For example his statement regarding the distribution of hair on the human extremities is in- complete and inexact, and his attribution of gigantism to deficiency of pituitary secretion is mistaken. Perhaps the least satisfactory chapter is that on biometrics. We have submitted this to several graduates who all agree that the uninitiated RECENT AND PERIODICAL LITERATURE. 197 reader is not likely to make much of Dr. Cutler's exposition. In our opinion it would be an improvement if the greater part of this chapter were replaced by a paragraph stating the value of mathematical methods and referring readers desiring fuller information to some suitable text-book. This would leave space for rele- vant matter omitted or receiving merely casual mention, e.g., the ancestry of the elephant, mimicry, sexual selection, the imperfect adaptation of man to the upright posture, and a summary of recent discoveries of extinct varieties of the human species. As a text-book the utility of the volume would be increased by a greater use of differential type; questions for review; a glossary giving the deriva- tion and meaning of scientific terms likely to be unfamiliar; and direct references to easily accessible sources of fuller information wherever the author feels that his limitations of space have prevented his saying all he would like to. It is a serious fault of the Bibliography that the inquiring reader is referred to oid editions of books of which recent revised editions are available. WV. B. DRUMMOND. Dell, J. A., M.Sc. Animals in the Making: an Introduction to the Study of Development. G. Bell & Sons (Bell's Natural Science Series). London, 1925. Pp. xii-F115. P. 8; figs. 31. Price 2s. 6d. "THE object of this book," in the author's words, "is to introduce the study of the changes in form which animals undergo during their development," and it ,embodies the results of eight years' teaching experience in a boys' school. The nature of growth and reproduction is lucidy set forth in six chapters dealing with the development of the frog, chick and rabbit, and other chapters are devoted to the use of the microscope and lenses, and to the cell-theory. There is a useful appendix ,on apparatus and materials. The wealth of practical detail should make the book of value to teachers faced with the difficult task of instructing children of second- ary school age in the facts of development. A. E. ELLIS. Dublin, Louis I., Ph.D., Statistician. The Excesses of Birth Control. Address delivered before the Sixth International Neo-Malthusian Birth Control Conference, Hotel McAlpin, New York City, 1925. IT is always refreshing to read the other side of a controversy, and Dr. Dublin frankly placed his dissenting views before the convention at the invitation of the President, Mrs. Sanger. He stated at the outset that the "propaganda of the con- vention had been based on an emotional reaction and not on a scientific analysis." He considered that the larger population problem was a bigger issue than the pre- ference of the individual. Dr. Dublin's objections to the programme of the Birth Control Conference were stated in further detail under the following headings: (1) Disregard of the interest of the State. He asserted that their literature presumed that parenthood was entirely an individual affair.
