"The earlier chapters describing glacial action, and the traces of it in North America--especially the defining of its limits, such as the terminal moraine of the great movement itself--are of great interest and value. The maps and diagrams are of much assistance in enabling the reader to grasp the vast extent of the movement."--_London Spectator_. New York: D. APPLETON & CO., 72 Fifth Avenue. * * * * * D. APPLETON & CO.'S PUBLICATIONS. _PRINCIPLES OF GEOLOGY; or, the Modern Changes of the Earth and its Inhabitants, considered as illustrative of Geology._ By Sir Charles Lyell, Bart. Illustrated with Maps, Plates, and Woodcuts. Two vols., royal 8vo. Cloth, $8.00. The "Principles of Geology" may be looked upon with pride, not only as a representative of English Science, but as without a rival of its kind anywhere. Growing in fullness and accuracy with the growth of experience and observation in every region of the world, the work has incorporated with itself each established discovery, and has been modified by every hypothesis of value which has been brought to bear upon, or been evolved from, the most recent body of facts. _THE AUTOBIOGRAPHY OF THE EARTH: A Popular Account of Geological history._ By Rev. H. N. Hutchinson, B. A., F. G. S. With 27 Illustrations. Crown 8vo. Cloth, $1.50. "A scientific work, divested of technicalities, and put into a bright, narrative form which can not but attract even the most general reader."--_Boston Transcript_. "It is hardly conceivable that the rich results of the science of geology can be so treated as to prove uninteresting to thinking people, be they young or old. When, therefore, we say that Mr. Hutchinson's book is extremely interesting, no more might be implied than that the author has skillfully used the vast materials at his hand. But Mr. Hutchinson has successfully carried out a difficult design on an admirable plan, and has adhered to that plan throughout. His sketch of historical geology has a genuine continuity."--_Saturday Review_. _A REPRINT OF ANNUAL REPORTS AND OTHER PAPERS OF THE GEOLOGY OF THE VIRGINIAS._ By the late William Barton Rogers, LL. D., etc., Director of the Geological Survey of Virginia from 1835 to 1841. With numerous Maps, Colored Charts, etc. 12mo. Cloth, $5.00. _NATURAL RESOURCES OF THE UNITED STATES._ By Jacob Harris Patton, M. A., Ph. D. 8vo. 523 pages. Cloth, $3.00. "This portly octavo of over 500 pages is an encyclopedic directory to its subject, and a work of comprehensive scope, exhaustive research, scientific spirit, and good literary form.... Capitalists, investors, railroad projectors, land speculators, and all who need to know the distribution of land values, will find a vast amount of information in this well-arranged work, the contents of which, it is safe to say, could not be found assembled in similar compass elsewhere."--_Boston Literary World_.
