I hâve kept the fundamental prinoiples of the subject well to the front from the very beginning. At the same time I bave not forgotten, what every mathematical (and other) teacher should hâve perpetually in mind, that a genei-al proposition is a propertjof no value to one that bas not mastered the particulars. The utmost rigour of accurate logical déduction bas therefore been less my aim than a graduai development of algebraic ideas. In arranging the exercises I bave actcd on a similar principle of keepingoutas far as possible questions that bave no theoretical or practical interest. — Préface.
