HEAT,

CONSIDERED AS A MODE OF MOTION,

Being a Course of Twelve Lectures delivered before the Royal Institution of Great Britain.
BY JOHN TYNDALL, F. R. S.
PROFESSOR OF NATURAL PHILOSOPHY IN THE ROYAL INSTITUTION—AUTHOR OF THE “GLACIERS OF THE ALPS.”
With One Hundred Illustrations. 8vo., 480 pages. Price, $2.00.

This volume is by the gifted successor of Faraday, the young Professor of Natural Philosophy in the Royal Institution of England. The author, himself celebrated as a discoverer, an ingenious and fertile experimenter, a bold but disciplined thinker, a vivid and imaginative speaker, and dealing with the most splendid generalizations and the grandest phenomena of nature, was listened to with the profoundest attention. The new views of the nature of heat, its connections with the other forms of force, and the sublime part it plays in the scheme of Nature—views which have but recently been adopted in the scientific world—are here for the first time brought forward, and illustrated with a resource of experiment, a brilliancy of illustration, and a clearness and eloquence of style for which Professor Tyndall is unequalled.

From the American Journal of Science.—With all the skill which has made Faraday the master of experimental science in Great Britain, Professor Tyndall enjoys the advantage of a superior general culture, and is thus enabled to set forth his philosophy with all the graces of eloquence and the finish of superior diction. With a simplicity, and absence of technicalities which render his explanations lucid to unscientific minds, and at the same time a thoroughness and originality by which he instructs the most learned, he unfolds all the modern philosophy of heat.

New York Times.—Professor Tyndall’s course of lectures on heat is one of the most beautiful illustrations of a mode of handling scientific subjects, which is comparatively new, and which promises the best results, both to science and to literature generally; we mean the treatment of subjects in a style at once profound and popular. The title of Professor Tyndall’s work indicates the theory of heat held by him, and indeed the only one now held by scientific men—it is a mode of motion.

Boston Journal.—He exhibits the curious and beautiful workings of nature in a most delightful manner. Before the reader particles of water lock themselves or fly asunder with a movement regulated like a dance. They form themselves into liquid flowers with fine serrated petals, or into rosettes of frozen gauze, they bound upward in boiling fountains, or creep slowly onward in stupendous glaciers. Flames burst into music and sing, or cease to sing, as the experimenter pleases, and metals paint themselves upon a screen in dazzling hues as the painter touches his canvas.

New York Tribune.—The most original and important contribution that has yet been made to the theory and literature of thermotics.

Scientific American.—The work is written in a charming style, and is the most valuable contribution to scientific literature that has been published in many years. It is the most popular exposition of the dynamical theory of heat that has yet appeared. The old material theory of heat may be said to be defunct.

Louisville Democrat.—This is one of the most delightful scientific works we have ever met. The lectures are so full of life and spirit that we can almost imagine the lecturer before us, and see his brilliant experiments in every stage of their progress. The theory is so carefully and thoroughly explained that no one can fail to understand it. Such books as these create a love for science.

Troy Whig.—No one can take up these lectures and pursue the general train and scope of thought which they compel, without having attained already to a love of practical science which will inevitably impress itself on his mental habits hereafter.

Independent.—Professor Tyndall’s expositions and experiments are remarkably thoughtful, ingenious, clear and convincing; portions of the book have almost the interest of a romance, so startling are the descriptions and elucidations.

The Life and Correspondence of THEODORE PARKER,

Minister of the Twenty-eighth Congregational Society, Boston. By John Weiss. With two Portraits on Steel, fac-simile of Handwriting, and nineteen Wood Engravings. 2 vols., 8vo. 1,008 pages. Price, $6.

“These volumes contain an account of Mr. Parker’s childhood and self-education; of the development of his theological ideas; of his scholarly and philosophical pursuits; and of his relation to the Anti-Slavery cause, and to the epoch in America which preceded the civil war. His two visits to Europe are described in letters and extracts from his journal. An autobiographical fragment is introduced in relation to Mr. Parker’s early life, and his letters of friendship on literary, speculative, and political topics are freely interspersed. The illustrations represent scenes connected with various periods of Mr. Parker’s life, the houses he dwelt in, his country haunts, the meeting house, his library, and the Music Hall in which he preached.”


Catechism of the Steam Engine,

In its various Applications to Mines, Mills, Steam Navigation, Railways, and Agriculture. With Practical Instructions for the Manufacture and Management of Engines of every Class. By John Bourne, C. E. New and Revised Edition. 1 vol., 12mo. Illustrated. Cloth. $2.

“In offering to the American public a reprint of a work on the Steam Engine so deservedly successful, and so long considered standard, the Publishers have not thought it necessary that it should be an exact copy of the English edition. There were some details in which they thought it could be improved and better adapted to the use of American Engineers. On this account the size of the page has been increased to a full 12mo, to admit of larger illustrations, which, in the English edition, are often on too small a scale, and some of the illustrations themselves have been supplied by others equally applicable, more recent, and to us more familiar examples. The first part of Chapter XI., devoted in the English edition to English portable and fixed agricultural engines, in this edition gives place entirely to illustrations from American practice, of steam engines as applied to different purposes, and of appliances and machines necessary to them. But with the exception of some of the illustrations and the description of them, and the correction of a few typographical errors, this edition is a faithful transcript of the latest English edition.”
