PREFACE.

In the following work it has been the endeavor to put the science of Arithmetic on a sound basis, and to give clear and complete explanations of all the fundamental principles and processes. It has not been the aim to introduce novelties, but to promote accuracy and clearness of conception, so as to make the study of Arithmetic not only of practical utility, but also of great educational value.

Í am indebted to many friends for their kindness in looking over the proof sheets, for help in the verification of the answers, and for valuable criticisms and suggestions. My special thanks are due to Mr. J. Barnard, M. A., Head Mathematical Master at Christ's Hospital.

PREFACE.

My share in this work has been performed with the expectation of giving to the teachers of our Preparatory Schools an Arithmetic which will induce close thought by the student and at the same time open to him a knowledge of the reasons for the several processes which he will be compelled to investigate.

I am under special obligations to Mr. E. H. Schuyler for his kindly criticisms, and to Mr. C. H. Gorsline for his suggestions in regard to the Chapters on the applications of Arithmetic to business calculations and forms.
