Excerpt from Ohio FossilsDuring the preparation of this bulletin we have had much help and encouragement which it is a pleasure to acknowledge. Dr. J. E. Carman allowed us to draw on his thorough and detailed knowledge of Ohio stratigraphy and paleontology; his kindly and searching criticism of the manuscript is much appreciated. Mr. R. E. Lamborn and Miss Pauline Smyth of the Ohio Division of Geological Survey read parts of the manuscript and contributed information on topics with which they are particularly familiar. Mr. W. C. Brown, also of the Survey, gave us much good advice on many points important to the non-geologist. Dr. J. M. Schopf, of the United States Geological Survey, read the part of the text dealing with fossil plants and his advice on that subject is gratefully acknowledged. Mr. R. S. Bowman gave us much information on Silurian fossils. Dr. E. S. Thomas, Curator of Natural History at the Ohio State Museum, gave us his impressions of the text from the standpoint of a naturalist. Our colleagues in the department of geology at the Ohio State University, Drs. C. A. Lamey, J. O. Fuller, R. P. Goldthwait, H. J. Pincus, M. P. Weiss, ands. E. White, have read the manuscript in its final stages and have contributed useful information on many points.Finally, we realize that in spite of much care and revision we may have made inadvertent errors or failed to mention or emphasize pertinent topics. We shall be grateful to anyone who will be good enough to call our attention to these faults and we shall endeavor to correct them in later editions of this bulletin.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
