Few, it any works on Arithmetic, have received the approbation which has been bestowed upon “Ray's Arithmetic, Part Third;" and the constantly increasing demand for it having rendered another renewal of the stereotype plates necessary. it lias been made the occasion for remodeling and greatly improving the volume in all its parts.
The Inductive and Analytic methods here adopted, lead the learner to an understanding of the principles from which the rules are derived, and teach him to regard rules as results rather than reasons: he will understand the "why and 2 herefore" of every operation performed, and gain a thorough knowledge of the principles of Arithmetic with its applications, wliile the faculties of the mind are strengthened and disciplined.
The leading features of the work are: 1st. Every principle is clearly explained by an analysis or solution of simple examples, from which a Rule is derived. This is followed by graduated exercises designed to render the pupil familiar with its application.
20. The arrangement is strictly philosophical; no principle is anticipated: the pupil is never required to perform any operation until the principle on which it is founded has first been explained. For this reason, those processes of reduction that require the use of fractions, are introduced after fractions.
3d. The subject of Fractions, a thorough understanding of which is almost a knowledge of Aritlimetic, has received that attention which its use and importance demand.
4th. The subject of Proportion is introduced immediately after Decimals; this ena hles the instructor to treat Percentage and its various applications, either by proportion, or by analysis, as he may prefer.
