PREFACE.

In revising this edition of Walkinghame's Arithmetic, I have carefully endeavoured to adapt it to the requirements of the present day, and in doing so, have completely altered some portions of the work.

I have placed Fractions (both Vulgar and Decimal) before Proportion; clearly explained the system of working sums in Mensuration by Vulgar Fractions; have added new and useful Examples in many of the Rules, and considerably increased the number of Miscellaneous Examples, I trust, with considerable advantage to this favourite School-book.
