The advanced lesson book, by E.T. Stevens and C. Hole

to furnish his pupils with examples to be worked at home or otherwise. They have given a collection of short rules and definitions in order that the pupil may be enabled to refresh his memory, if necessary, as to the various processes which have been taught in class. In order that the pupil may be enabled to read the lessons with appreciation, the most difficult words and forms of expression in each extract are explained, as far as possible, in the sense in which they are used. These definitions are prefixed to the lesson, and may be advantageously committed to memory by the pupil before he reads it.

The Editors issue the book in the earnest hope that they may become, through it, humble co-workers with those who are engaged in the noble task of opening up the fountains of knowledge to that class of youths and young men who are destined to play so important a part in the future of this country.
