Sir RONALD ROSS Published at the beginning of JANUARY, APRIL, JULY, OCTOBER Each number consists of about 192 pages, contributed by authorities in their respective subjects. Illustrated. 6s. net. Annual Subscription, including postage, 25s. 6d. SCIENCE PROGRESS owes its origin to an endeavor to found a scientific journal containing original papers and summaries of the present state of knowledge in all branches of science. The necessity for such a journal is to be found in the fact that, with the specialization which necessarily accompanies the modern development of scientific thought and work, it is increasingly difficult for even the professional man of science to keep in touch with the trend of thought and the progress achieved in subjects other than those in which his immediate interests lie. This difficulty is felt by teachers and students in colleges and schools, and by the general educated public interested in scientific questions. SCIENCE PROGRESS claims to have filled this want.

"Described in more of detail, the book as a whole constitutes a constructive and systematic survey of the whole field of the principles of the exact sciences from the standpoint of a logical idealism which is historically derived from Kant, but which lacks 'the fatal rigidity' of the latter's system. As the author develops his idealistic view, it becomes a doctrine of creative intelligence, showing it to be neither idealism, pragmatism nor realism; as these terms are understood by us, it is rather 'a positivistic and non-static rationalism which seeks to preserve the spirit that unites Plato, Descartes, Leibnitz and Kant, and to show how this spirit reaches its fulfillment in the modern development of mathematical and physical theory."-Boston Evening Transcript. "In the last hundred pages or so of the book, the author comes to the exposition of Einstein's theory proper, and here his manuscript has been revised by Einstein himself. This is a most noteworthy contribution and brings the abstract mathematical conceptions of relativity clearly into the philosophical and even psychological field better than anything which has yet appeared."-The Pedagogical Seminary.
