29. : -Problems of Life and Reproduction. By MARCUS HARTOG, 

 D. Sc., Professor of Zoology in University College, Cork. 8vo. 



The author uses all the legitimate arms of scientific controversy in assailing 

 certain views that have been widely pressed on the general public with an assurance 

 that must have given many the impression that they were protected by the universal 

 consensus of biologists. Among the subjects considered are: "The Cellular Pedi- 

 gree and the Problem of Heredity"; "The Relation of Brood-Formation to Ordinary 

 Cell-Division"; "The New Force, Mitokinetism"; /'Nuclear Reduction and the 

 Function of Chroism"; " Fertilization"; " The Transmission of Acquired Characters"; 

 "Mechanism and Life"; "The Biological Writings of Samuel Butler"; "Interpola- 

 tion in Memory"; "The Teaching of Nature Study." 



30. Problems of the Sexes. By JEAN FINOT, Author of "The Science 

 of Happiness," etc. Translated under authority by Mary J. 

 Safford. 8vo. 



A masterly presentation of the attitude of the ages toward women and an elo- 

 quent plea for her further enfranchisement from imposed and unnatural limitations. 

 The range of scholarship that has been enlisted in the writing may well excite one's 

 wonder, but the tone of the book is popular and its appeal is not to any small section 

 of the reading public but to all the classes and degrees of an age that, from present 

 indications, will go down in history as the century of Woman. 



31. The Positive Evolution of Religion. Its Moral and Social Re- 

 action. By FREDERIC HARRISON. 8vo. 



The author has undertaken to estimate the moral and social reaction of various 

 forms of Religion beginning with Nature Worship, Polytheism, Catholicism, 

 Protestantism, and Deism. The volume may be looked upon as the final word, the 

 summary of the celebrated author's philosophy a systematic study of the entire 

 religious problem. 



32. The Science of Happiness. By JEAN FINOT, Author of "Prob- 

 lems of the Sexes, " etc. Translated from the French by Mary J. 

 Safford. 8. 



In this work, which was crowned by the Academy, the author considers a 

 subject, the solution of which offers more enticement to the well-wisher of the race 

 than the gold of the Incas did to the treasure-seekers of Spain, who themselves 

 doubtless looked upon the coveted yellow metal, however mistakenly, as a key to 

 the happiness which all are trying to find. "Amid the noisy tumult of life, amid the 

 dissonance that divides man from man," remarks M. Finot, "the Science of Happiness 

 tries to discover the divine link which binds humanity to happiness through the soul 

 and through the union of souls." The author considers the nature of happiness and 

 the means of its attainment, as well as many allied questions. 



33. Genetic Theory of Reality. Being the Outcome of Genetic Logic 

 as Issuing in the ^Esthetic Theory of Reality Called Pancalism. 

 By JAMES MARK BALDWIN, Ph.D., D.Sc., LL.D., Foreign Corre- 

 spondent of the Institute of France, Author of " History of Psycho- 

 logy," etc. 



The author here states the general results of the extended studies in genetic and 

 social science and anthropology made by him and others, and gives a critical account 

 of the history of the interpretation of nature and man, both racial and philosophical. 



The book offers an Introduction to Philosophy from a new point of view. It 

 contains, also, a valuable glossary of the terms employed in these and similar 

 discussions. 



34. Mosquito Control in Panama The Eradication of Malaria and 

 Yellow Fever in Cuba and Panama. By J. A. LE PRINCE, C.E., A. 

 M., Chief Sanitary Inspector, Isthmian Canal Commission, 1904- 

 191.}, and A. J. ORENSTEIN, M.D., Assistant Chief Sanitary Inspec- 

 tor, Isthmian Canal Commission. With an introduction by L. O. 

 HOWARD, Ph.D., Entomologist and Chief, Bureau of Entomology, 

 United States Department of Agriculture. 8. 95 illustrations. 



Mr. Le Prince's books will be not only of great practical importance as a 

 guide to future work of the same character, especially in the Tropics, but also 

 of permanent historic value. 



35. The Organism as a Whole. From a Physico-Chemical Viewpoint. 



By JACQUES LOEB, Author of " Comparative Physiology of the 



Brain." 8. 



The author accounts for the harmonious character of the organism on a purely 

 physico-chemical basis, without the assumption of design on the one hand, and 

 without the formulation of too definite a theory of evolution on the other. The 

 book contains, in addition to the text, all the necessary illustrations.
