I hâve kept the fundamental principles of the Bubject well to the front from the verjbeginning. At the same time I bave not forgotten, what every mathematical (and other) teacher should bave perpetually in mind, that a gênerai proposition is a property of no value to one that bas not mastered the particulars. The utniost rigour of acciirate logical déduction bas therefore been less mj aim than a graduai development of algebraic ideas. In arranging the exercises I bave acted on a similar principle of keepingoutas far as possible questions that hâve no theoretical or practical interest. — Préface.
