Price, $5.00. _From the London Saturday Review._ “In this excellent translation of Professor Haeckel’s work, the English reader has access to the latest doctrines of the Continental school of evolution, in its application to the history or man. It is in Germany, beyond any other European country, that the impulse given by Darwin twenty years ago to the theory of evolution has influenced the whole tenor of philosophical opinion. There may be, and are, differences in the degree to which the doctrine may be held capable of extension into the domain of mind and morals; but there is no denying, in scientific circles at least, that as regards the physical history of organic nature much has been done toward making good a continuous scheme of being.” THE HISTORY OF CREATION; or, the Development of the Earth and its Inhabitants by the Action of Natural Causes.
