UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margwis, and improper alignment can adversely affect reproduction. in the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to t>e removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawir^gs, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overiaps. Photographs included in the original manuscript have t>een reproduced xerographically in this copy. Higher quality 6' x 9' t>lack and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directiy to order.

Special thanks also to the libraries of the University of Maryland at College Park, which quite helpfully extended library privileges, and the Johns Hopkins University; to the Library' of Congress; and to Marylene Altieri of Gutman Library Special Collections at the Harvard University Graduate School of Education. The interlibrar\' loan departments of the University of Maryland at College Park and Iowa State Universit}' also proffered assistance with obtaining materials for the project. A long-distance move made this dissertation even more of an independent project than most, but the advice and guidance of major professor David B. Wilson was still indispensable. The author acknowledges her committee as well; Andrejs Plakans, Alan I Marcus, James Murdock, and Amy Sue Bix. Various members of the Canadian Society for the History and Philosophy of Mathematics have also provided encouragement along the way. Finally, thanks to Nelson Hastings for funding the research and cooking dinner. ix ABSTRACT The stor\' of geometry' education in the American college has been subject to neglect, with most historians assuming that all available information was published in
