IN submitting to the public a translation of Lefébure de Fourcy's admirable treatise on Trigonometry, I have thought it not inappropriate to associate your name with this effort to promote the interests of education. You have given your influence, by precept and example, to this important cause, and in dedicating this work to you, I only give expression to the general sentiment of those who appreciate the weight of this great influence. The personal and official relations which it has been my privilege to sustain towards you, during a period of more than thirty years, add a peculiar gratification to me in rendering this tribute of affectionate regard and esteem. VIRGINIA MILITARY INSTITUTE, Lexington, Va., September 19, 1867. FRANCIS H. SMITH. (iii) |
