The unscientific reader who may have perused without thoroughly comprehending, Darwin's much abused work on "The Origin of Species," and that larger class of reader who have only heard of the book in question, will find in the present publication an admirable help to the understanding of Mr. Darwin's somewhat abstruse theory. Prof. Huxley is a firm believer in the bold and original speculations of that writer, and in a series of six lectures to an audience of workingmen in England, undertook to present in the simplest and most popular form the ideas of organic nature advanced in the treatise of Mr. Darwin. The lectures were taken from the speaker's lips by short-hand, and hence have all the clearness, directness and force which belong to the circumstances of their delivery. In this respect the work is of great value. Dealing with the most abstruse and fundamental questions of mind and organization, these subjects are nevertheless presented in so lucid and attractive a manner as to impress vividly the commonest imagination.
