Key, to a mathematical work, is very proper in its place ;but to be constantly at hand, and consulted too often, might prove injurious: we must not, however, confound the improper use of a thing with the thing itself. Those who condemn keys, in general terms, should condemn teachers also; for a key is neither more nor less than a teacher, in another shape. The self-taught are generally sound and vigorous; but if they disregard the works and teachings of others, they will be found to be wanting in that certain symmetry and polish of mind, so characteristic of educated men. So it is with an algebraist; he may go through his text-books, solve every problem, independent of all external aid, and if he does not compare his work with the works of others, he cannot know whether he is skillful or otherwise; for it is only by comparison that we measure excellence. No solution of a problem, or of an equation, should be called good, if better can be found; hence it is important that more than one standard of attainment should be before the pupil; and those who really become eminent, in any science, are those whose talents and dispositions enable them to gather knowledge from every possible source.

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
