About This Book

The text introduces young readers to foundational physical principles through short, plain explanations and practical examples. Chapters cover the solar system and day–night cycles, properties of light and color, heat and its transfer, properties of air and water, sound and vibration, basic matter and forces including cohesion and gravity, motion and centres of gravity, mechanical powers such as levers, wheels, pulleys, and screws, and elementary electricity and magnetism. Each topic is explained in accessible language with diagrams, everyday illustrations, and questions designed to train observation and reasoning.

What must each station have?

Each station must have both a key and a receiver, so as to send as well as receive messages.

What is the Atlantic cable?

The Atlantic cable is a telegraphic wire reaching across the Atlantic Ocean, from America to Europe.

When was the first Atlantic cable laid?

The first Atlantic cable was successfully laid in 1866, between Newfoundland and Ireland. It is eighteen hundred and sixty-four miles long, and its success is chiefly due to Cyrus W. Field.

Of what use is the Atlantic cable?

The Atlantic cable forms a telegraphic connection between Europe and America, so that news may be sent from one country to the other in a few moments of time; thus the people of the two continents, although so far apart, can communicate with each other many times in a single day.

THE
Elements of Natural Philosophy

By E. J. HOUSTON, A.M.,
Professor of Physics and Physical Geography in the Central High School, Philadelphia, Pa.

This book is intended for Graded Schools, Academies, Seminaries, Normal Schools, etc. It gives the elements of the science in a concise form and in logical sequence, so that the book forms a system of Natural Philosophy, and not a mere collection of disconnected facts. It is fully “up to the times” in every respect, and gives full descriptions of the more important discoveries lately made in Physical Science; the Electric Light, the Telephone, the Microphone, the Phonograph, etc., are all described and illustrated. An examination of the work will show that no expense has been spared to bring it up to the highest standard as regards illustration and typography.

We invite the attention of Teachers to our Publications, a Catalogue of which will be sent on application. On our List will be found some of the most popular of modern Text-Books.
