always been the mainstay of the elementary embryologist. Hence we know more about the processes and transformations by means of which its egg develops than we do about these same occurrences in any other egg; and, as it is believed that the process which goes on in one egg is, in a general way, a counterpart of that which goes on in all other eggs, we can, by studying the development of the frog's egg, get a fairly good idea of the embryology of all the other animals hatched from eggs. This book is a careful microscopic following of the process of development in a frog's egg from the time when the egg is forming to the moment when the young tadpole issues from the jelly membranes. Especial weight, however, is laid on the results of experimental work, tending to modify in various ways the normal process. Illustrations are used wherever they tend to simplify the text.
An essay on The Psychical Correlation of Religious Emotion and Sexual Desire has been published by Dr. James Weir, Jr., in a tastefully got up pamphlet. He shows the connection between erato-mania and religious mania by facts drawn from Greek and Roman history, the history of celibate religious orders, and various anthropological investigations. The author believes that upon this correlation depends, in a great measure, the stability of sexual morality. (The author, Owensboro, Ky.)
Art Education, the True Industrial Education, by W. T. Harris (second edition, Bardeen, 50 cents), is an address delivered before the National Educational Association at the meeting in Nashville in 1889. Dr. Harris contends that æsthetic education—the cultivation of taste, the acquirement of knowledge on the subject of the origin of the idea of beauty (both its historic origin and the philosophical account of its source in human nature), the practice of producing the outlines of the beautiful by the arts of drawing, painting, and modeling, the criticism of works of art—all these things we must claim form the true foundation of the highest success in the industries of any modern nation." Dr. Harris, with his well-known clear and incisive reasoning, supports this thesis through twenty-two pages.
