This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Since the publication of our first paper on the Crinoids, it has been our aim to direct our special attention to studying the morphology of the vari ous groups as they appeared to us, with a view to future classification, and to revise the work of the previous writers. The various classifications which had been proposed were not based upon strictly morphological principles, and in many cases widely distinct forms were placed together in the same group.

Charles Wachsmuth was an American paleontologist born in Hanover.
Background
Charles Wachsmuth was born in the city of Hanover, Germany, the only son of Christian Wachsmuth, a lawyer and member of the Frankfurt Parliament of 1848. Although the boy was in feeble health almost from the hour of his birth, his father decided to prepare him for the law.
Education
He was educated as a lawyer.
Career
He was obliged to give up his studies, and, upon advice of his physician, entered a mercantile house in Hamburg. In 1852 he was sent to New York as an agent of the company, and about two years later he went west, and settled in Burlington, Iowa, where he entered the grocery business. In the meanwhile, in an effort to regain his health in the out-of-doors, he devoted his leisure to the collecting of fossils. In 1865 the business prospered so that he was able to retire and to devote all of his time to collecting and studying - a pursuit that he enjoyed with signal success to his very last day. He acquired large collections of the rare crinoids and a special library on the subject which attracted the attention of scientists the world over. Louis Agassiz, on one of his western lecturing tours, visited him, became very enthusiastic over the acquirements, and in 1873 purchased the material for the Museum of Comparative Zoology at Cambridge. He induced Wachsmuth to go to Cambridge with him, where he could continue his studies to greater advantage, and Wachsmuth worked with Agassiz until the latter's death in December of that year. Returning once more to Burlington, he began to make a new collection, but with very different and much enlarged ideas from those that he had previously held. He soon made the acquaintance of a young lawyer, Frank Springer, who had a strong interest in crinoids, and the friendship of the two men developed into a partnership that lasted through life. The joint plan of Springer and Wachsmuth was a pretentious one. It involved the personal critical examination of all the collections of crinoids throughout the world, and a complete revision of everything ever described. This stupendous undertaking occupied fifty years, the work being carried on by Springer alone for twenty years after Wachsmuth's death.
The resulting monumental monograph, North American Crinoidea Camerata, superbly illustrated, was dedicated to Agassiz and appeared in 1897 as volumes XX and XXI of the Memoirs of the Museum of Comparative Zoology. Usually associated with Springer, Wachsmuth published numerous other memoirs on the morphology of the crinoids. Some of the most important appeared in the Proceedings of the American Academy of Natural Sciences in Philadelphia: "Transition Forms in Crinoids", "The Summit Plates in Blastoids, Crinoids, and Cystids", "Discovery of the Ventral Structure of Taxocrinus and Haplocrinus", and "The Perisomic Plates of Crinoids". His "Notes on the Internal and External Structure of Paleozoic Crinoids" appeared in the American Journal of Science and Art, August 1877. A complete bibliography of his publications is to be found in the American Geologist. After Wachsmuth's death, several monographs left unfinished were completed by Springer. He was interred at Aspen Grove Cemetery, Burlington.
