The chapter of Miscellaneous Examples will afford a valuable and thorough drill to the advanced student of arithmetic or algebra. They contain a great variety of principles, and while they may be considered difficult, yet the full analysis given of every principle, and the selection of numbers so adapted to the conditions of the question as to produce results free from large and difficult fractions, will render a mental solution of them comparatively easy. In conclusion, we may be allowed to express the belief, that in this work the thorough teacher will find a desideratum long sought in this department of science, the means of mental discipline and development such as has been furnished by no similar treatise. THE AUTHOR. SUGGESTIONS TO TEACHERS. Pupils of nearly the same degree of advancement should be classed together. Regular exercises should be assigned to the class, and sufficient time allowed them to thoroughly examine their lesson before being called upon to recite. The use of the book at the time of recitation should be strictly prohibited, except, perhaps, in some of the more difficult lessons in the latter part of the work. Each example should be read but once, slowly and distinctly, the pupils called upon promiscuously, who should arise, stand erect, repeat the example, and then give the analysis. This will secure close attention. Every question should be clearly and thoroughly analyzed, and the pupil required to adhere strictly to the forms of solution given, unless better ones can be substituted; and in no case should he be allowed to omit the conclusion, commencing with "Therefore." The class should be encouraged to detect and correct errors in statement or analysis, to criticise and make proper inquiries, all of which should be signaled by the uplifted hand. 66 It is suggested that the class be occasionally exercised upon Ringing the Changes," as explained in the Appendix, and which may be applied to a great number and variety of examples. It will not only afford a valuable drill, but a pleasant and enlivening exercise. INTELLECTUAL ARITHMETIC. CHAPTER I. ADDITION. 1. 1.

Eli paid 9 shillings for a pair of skates, and 6 shillings for a cap; how many shillings did he pay for both? ANALYSIS.
