Excerpt from The Complete Arithmetic: Oral and Written Great pains have also been taken to make this work superior to all others in its typographical arrangement and finish, and in the general tastefulness of its mechanical execution. The author takes pleasure in acknowledging his indebtedness for many valuable suggestions received from teachers of experience and others interested in the work of education; especially to Joseph Ficklin, Ph. D., Professor of Mathematics in the University of Missouri, by whom chiefly the sections upon Involution, Evolution, Progressions, and Annuities have been prepared as well as to Henry Kiddle, A. M., Superintendent of Schools in the city of New York, for valuable assistance, especially in the higher departments of Percentage, and for important suggestions in relation to other parts of the work. How nearly the author has accomplished his purpose, to give to the public, in one volume, a clear, scientific, and complete treatise on this subject, combining and systematizing many real improvements of practical value and importance to the business man and the student, the intelligent and experienced educator must decide.
