This subject is too apt to be neglected, but the fault has been with the text books. Here is a book which gives the latest view of the whole subject adequate treatment in the briefest space and most entertaining manner. Price, $1.00.

BARNES’ NEW ARITHMETICS.

In two books. This series is the work of Prof. Joseph Ficklin and others, and may be said to represent the outgrowth of our previous mathematical publications by Charles Davies, William G. Peck, etc. They present the clearest possible course of instruction, giving a minimum of theory with a maximum of practice. They are very widely approved. Prices, elementary, 35c.; national, 75c.

BARNES’ BRIEF HISTORY SERIES.

The United States, France, Greece, ancient peoples, mediæval and modern peoples, and the General History of the world, are treated in separate volumes, all of moderate size, profusely but judiciously illustrated, and skillfully arranged with the necessities of the class room constantly in view. They have been the models upon which other subsequent publications have been made, but are still unrivaled and alone. They are more widely introduced in some sections than all other series combined.

STEELE’S SCIENCE TEXTS.

Seven volumes. Each volume on a separate subject, viz.: Philosophy, Chemistry, Astronomy, Geology, Zoology, Botany and Physiology. No one has ever succeeded in awakening a love for science in young minds equal to Steele. His plan is scientific and treatment popular. In each branch he has had the co-operation of specialists.
