Produktbeschreibung
Excerpt from Johnson´s Natural Philosophy, and Key to Philosophical Charts: Illustrated With 500 Cuts; Being Reduced Photographic Copies of All the Diagrams Contained in the Author´s Philosophical Series of Indestructible School Charts; For the Use of Schools and Families The rapid diffusion of scientific knowledge, and the continually widening field of its application to the useful pursuits of life, have created an increased demand for new and improved means of teaching the various branches of Natural Philosophy. But no want is more generally felt, especially in common-schools and academies, than the necessity of Philosophical Diagrams, in the form of Wall Charts, to supply the absence of the expensive Philosophical Apparatus. To supply this want is the purpose of the Philosophical Series of the compiler´s Indestructible School Charts; to accompany and explain which, and provide a suitable text-book for schools and academies, are the objects of this volume. Before describing these, reference is here made to a Series of Charts prepared to supply this need, by the same compiler, in 1856; being a set of ten Philosophical Charts, 3 by 4 feet, embracing about two hundred diagrams, a large edition of which was readily sold; but, in consequence of the engravings being destroyed by fire, no subsequent editions were issued. To show the purpose of these Charts and the favor with which they were received at the time of their publication, we give the opinions of a few of the most distinguished men of the age: From Benjamin Silliman, LL.D., Prof. Emeritus in Yale College. Dr. Johnson´s Philosophical Charts are well worthy of the attention of all teachers and learners of the different branches of Natural Philosophy, to which they relate. The diagrams, drawn in colored or contrasted lines upon a black ground, are perfectly distinct and intelligible, and the large size and handsome mounting of the Charts give them a striking and attractive appearance. To teachers without apparatus, they must be an invaluable acquisition, and a very useful one to those who have the instruments. Such illustrations, as they speak to the mind through the eye, admit of indefinite extension to every branch of Natural Science. From Rev. Francis Wayland, D.D., LL.D., formerly Pres. of Brown University. I have carefully examined Dr. Johnson´s Philosophical Charts, and think them well adapted to the purposes for which they are intended. They will afford important aid to instructors in academies and schools where Philosophical Instruments are not furnished to perform illustrative experiments. In many cases they will also be of service even in addition to any ordinary apparatus. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
