A. 5. EducT 758.61.300 Standard Text-Books. MATHEMATICAL WORKS, BY GEO. R. PERKINS, LL. D., Perkins' Arithmetical Series Embraces four text-books, which cover the whole ground, from the State Normal School at Salem. take precedence of the more difficult; and nothing is anticipated to the bewilderment of the pupil. 5. They are inductive. General laws are deduced from individual cases. 6. They are practical, constructed with direct reference to the wants of the pupil when he shall enter on the actual business of life. 7. Rules and explanations are given tersely. Their point is not lost in a mass of words. 8. The examples, particularly those given first under the rules, do not involve tedious operations. 9. Each rule is illustrated by every variety of example that can fall under it. 10. The examples are so constructed as to require thought on the part of the pupil. 11. A principle once taught is not allowed to be forgotten. In one form or other it is made the subject of constant review. Standard Text-Books. 12. Finally, these Arithmetics teach the shortest, simplest, and most easy to be remembered modes of performing the different operations of which they treat. I. PRIMARY ARITHMETIC. 18mo. 160 pages. Price 21 cents. This work presupposes no knowledge of Arithmetic. It commences with Elementary principles, and lays a sure foundation for what is to follow. II. ELEMENTARY ARITHMETIC. 16mo. 347 pages. Price 42 cents. From the Primary the pupil proceeds to the Elementary, in which it is aimed to discipline the mind, to develop the reasoning powers, and to prepare the pupil for the advanced departments of Mathematics. In the author's treatment of Vulgar Fractions, Percentage, and Interest, his new method of finding the cash balance in Equation of Payments, and his improved method of Extracting the Cube Root, he has certainly made a great advance on the other Elementary Arithmetics now before the public. III. PRACTICAL ARITHMETIC. 12mo. 356 pages. Price, Cloth, 62 cents.—This work covers nearly the same ground as the Elementary, differing from it principally in presenting a greater number of examples. It may, therefore, either follow the Elementary, or be substituted for it. 324 pages. Cloth. IV. HIGHER ARITHMETIC. 12mo. Price 75 cents. This is intended as a finishing book for those who would complete a thorough arithmetical course. Perkins' Algebraic Series. I. ELEMENTS OF ALGEBRA. 12mo. 244 pages. Price 75 cents.-Adapted to the use of Common Schools and Academies. [SEE END OF THIS VOLUME. |
