They have been the standard in the leading colleges of the country since their publication. Chauvenet's Geometry is used at Harvard, Yale, West Point, and Annapolis. It has been copied by nearly every author who has written a geometry since its appearance. RECOMMENDATIONS, "I am glad to see at last an American text-book on this subject which is not from seventy-five to two thousand years behind the time, and which, without casting away what is good in the old, does not totally exclude the brilliant geometrical discoveries of the present century. I shall recommend its adoption as a text-book in this university."-PROF. J. W. SAFFORD, Director of the Dearborn Observatory, Chicago, Ill. "I regard Chauvenet's works on 'Geometry' and 'Trigonometry' as far above all others in merit. Their simplicity and scientific precision are everywhere praised. They are written from the stand-point of the higher analysis, but are made so clear that the most elementary minds may master them."-WM. T. HARRIS, ESQ., Superintendent of Public Schools, St. Louis, Mo. |
