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. [Illustration: Fruit bowl.] 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.
