THE PUBLISHERS BEG LEAVE TO CALL THE ATTENTION OF THE PUBLIC TO THE FOLLOWING UNSOLICITED NOTICES OF THE ELEMENTARY GEOLOGY, FROM GENTLEMEN EMINENTLY QUALIFIED TO JUDGE OF ITS MERITS. FROM PROF. B. SILLIMAN, LL. D. OF YALE COLLEGE. "I am greatly in fault in not having answered your kind letter of Aug. 20th. with a copy of your valuable work on Geology. I took the work with me to the west in the expectation of looking it over: and although I failed to read it satisfactorily, I glanced at it enough to convince me of its high value, and shall recommend it in my Lectures." FROM PROF. J. W. WEBSTER, OF HARVARD UNIVERSITY. "I have just received a copy of your "Elementary Geology," for which I beg you to accept many thanks. I am thankful that you have found time to present us with so excellent a view of the science, and shall recommend the work warmly to the class attending my lectures." FROM PROF. C. DEWEY, OF ROCHESTER, N. Y. "I introduced your Geology into our Academy. Part of it is hard reasoning for minds not pretty well matured. Still it is so vastly better than any thing in the English language with which I am acquainted, that I boast over it. It is admirable for the College course." FROM PROF. HENRY D. ROGERS, OF THE UNIVERSITY OF PENNSYL VANIA. "I thank you sincerely for a copy of your work, and yet more for presenting us with an Elementary Treatise on Geology in a form so well adapted to the wants of instructors. Having for several years past felt the want of just such a book for my Class in the University, I hailed its appearance with real satisfaction. FROM PROF. W. W. MATHER, GEOLOGIST TO ONE OF THE DISTRICTS OF N. YORK, AND TO THE STATE OF OHIO. "I have examined your little work on Geology with much interest and satisfaction. It presents a large mass of matter in a small compass; is lucid, concise, and its materials are arranged in the most convenient form for the student. It seems to form a happy medium between the more elementary books for schools, and those for the more advanced students of geology. Its copious references to various works on geology, will be a great advantage to those who choose to go to the original sources and dive deeper into the various subjects discussed." FROM PROF. J. W. BAILEY, OF THE MILITARY ACADEMY, WEST POINT. "I have recently perused with much pleasure, your Elementary Geology, and consider it a most valuable contribution to science, and highly creditable to yourself and our country. I am glad we have such a work to which to refer students. If I had known of your publication 2 sooner, I should have adopted it as our text book: but the Class had already provided themselves with Lyell's work. I shall recommend its adoption next year, if, as is almost certain, I meet with no work in the mean time better suited to our peculiar wants at this Institution." FROM PROF. C. B. ADAMS, OF MIDDLEBURY COLLEGE. "Your elementary book on geology has afforded me great pleasure : and I have, since our Catalogue was printed, adopted it as a text book." The following notices of the work, from among the many that have appeared, have been selected from some of the leading periodicals of the country. FROM THE AMERICAN JOURNAL OF SCIENCE AND ARTS, FOR OCTOBER, 1840. "The readers of this Journal and those who know the progress of American Geology, are well aware of the important services Prof. Hitchcock has rendered to this branch of science, through a period of many years, both by his laborious explorations and his written works. In the present instance, he has attempted to prepare a work which shall fill a vacancy long felt by the instructers of geology in this country, a work which, while it gives a good view of the progress of the science in other countries, draws its illustrations mainly from American facts. From the rapid glance which we have been able to bestow upon this performance, we should think that Prof. Hitchcock had succeeded in imparting this feature to his book." FROM THE AMERICAN BIBLICAL REPOSITORY, FOR OCTOBER, 1840. "The appearance of this volume from the pen of Prof. Hitchcock, will be peculiarly gratifying to many in the community. It is designed to be used as a Text Book for classes in geology, in Colleges and other Seminaries of learning, and also, to supply the wants of the general reader, who has not the leisure to study the numerous and extended treatises that have been written on different heads of this subject. The plan of it, we think, is admirably adapted to the first of these uses, and nearly or quite as well suited to the second." FROM THE NORTH AMERICAN REVIEW, FOR JANUARY, 1841. "Professor Hitchcock has been too long and favorably known to scientific men, both of the new world and of the old, to make it necessary for us to say, with what ample qualifications he undertakes the task before him. His work is no "secondary formation," based on the published works of European writers, but in every part bears the impress of acute and original observation, and happy tact in presenting the immense variety of subjects treated in the following Sections into which the book is divided." "The fifth Section is devoted to Organic Remains. It occupies one fourth of the whole work, and is illustrated with the best cuts in the book. We venture to say that there is not in our language so neat and compressed, yet so clear and correct, an account of the "Wonders of Geology." ELEMENTARY GEOLOGY. BY EDWARD HITCHCOCK, LL. D.
