PROCTOR, B.A. F.R.A.S. Author of 'Saturn and its System' &c. 'The idea of Mr. PROCTOR's book has manifestly been suggested by the famous controversy between Dr. WHEWELL and Sir DAVID BREWSTER respecting the plurality of worlds. Since the date of that combat a flood of new light has been thrown on the constitution of the solar system by the revelations obtained through the solar spectrum. We can now tell the materials of which the several planets are composed. We have ascertained with something like certainty which of these bodies are fitted to be the dwelling-place of such life as exists on our own earth. The surface of JUPITER is no longer a complete mystery; we know something of SATURN; and MARS has been so successfully surveyed that we possess something like an accurate chart of his continents and seas. Mr. PROCTOR describes many of the more recent scientific revelations on these subjects with such force and vividness that, even to the unscientific reader, his book is one of considerable interest.' DAILY TELEGRAPH. A book treating learnedly, yet simply and intelligibly, of those great questions concerning the laws of the universe of which the outside world has lately heard so much and understood so little, and written in such excellent English that its literary merits are nearly equal to its scientific value. ... The work differs from most of its class in being full of original matter, which though familiar to the astronomer is quite new to the general reader.' SCIENTIFIC OPINION. 'We can assure the reader that he will find in this volume the latest information and much that is interesting and important. The views expressed as to the constitution of the sidereal universe differ from those usually held, are clearly expressed and supported by strong arguments and original and forcible evidence. Mr. PROCTOR has evidently considered this subject carefully. In the part of the book which relates to the solar system useful information is more especially given to the non-scientific reader.' ATHENEUM. 'Probably no science during the last few years has made such rapid strides as astronomy. This advance is mainly owing to the discovery of the spectroscope, and its application to astronomical purposes. That wonderful instrument, more wonderful, perhaps, than the telescope, may be appropriately termed a light-sifter, and is used to analyse the light which comes to us from other orbs across the ocean of space, so as to set before us their general character and structure. The Author of the present work attempts to make use of the startling discoveries effected by the aid of the spectroscope, in order to form juster views of the structure and relations of the planetary and stellar systems. He again raises the question of the plurality of worlds, which a few years ago employed the scientific and dialectic skill of such men as Dr. WHEWELL and Sir DAVID BREWSTER, and ages before fascinated the early philosophers of ancient Greece. Mr. PROCTOR considers that science has progressed so rapidly of late that the subject of life in other worlds has assumed a new aspect since WHEWELL'S Plurality of Worlds and BREWSTER'S More Worlds than One, were written. Arguments which were hypothetical thirty years ago have either become certainties or been disproved. Doubtful points have been cleared up; a new meaning has been found even in those facts which were well known to both the disputants; and, lastly, a new mode of research has been devised, which has not only revealed a number of surprising facts, but promises to work yet greater marvels in the years which are to come. tainly Mr. PROCTOR has taken some pains and trouble to expound and illustrate his arguments and theories, and his work shews, moreover, much patient research and wide scientific reading. If we are occasionally compelled to differ from some of his conclusions, we cannot deny the fact that he has produced a most interesting work on a very fascinating subject.' EXAMINER.
