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.
