STODDARD, In the Clerk's Office of the District Court of the United States, for the Southern District of New York. PREFACE. 5145 I HAVE attempted in this work to present CLEARLY and CONCISELY, all those important principles and properties of numbers, which are necessary to a full comprehension of the higher branches of Mathematics, and their application to practical business and scientific calculations. The arrangement and illustration of these principles will enable the pupil to think for himself, independent of arbitrary rules, and summon to his aid on the instant all his arithmetical knowledge. This work treats extensively of mercantile transactions, interest, trade and barter, abbreviated arithmetical calculations, &c., and contains several principles not heretofore published, of extensive and practical application. A Key containing additional methods of analysis, and answers, (if deemed indispensable,) will be prepared for the use of Teachers. UNIVERSITY OF NORTHERN PENNSYLVANIA, } 4th, 1853. J. F. S.
