"This genial little volume is a child's book as to shortness, cheapness, and simplicity of style, though the author reasonably hopes that older people will use it as a source of information not popularly accessible elsewhere as to the life of Primitive Man and its relation to our own. . . . This book, if the time has come for the public to take to it, will have a certain effect in the world. It is not a mere compilation from the authors mentioned in the preface, but takes its own ground and stands by itself and for itself.

I have no doubt it will do good, and hope you will continue your work.

In the first of these books, after several chapters on the probable origin and mode of formation of the material universe at large, and on the nature and manner of operation of the solar energies, the chief part of the work is devoted to a consideration of organic life, its phenomena, origin, and perpetuation. The views of Mr. Darwin, his supporters and opponents, are fully discussed, and the evidences on either side carefully weighed. In a second part, the modern theories are compared with the Hebrew narrative, and the possibility of their reconciliation considered. The illustrations exhibit the beauties displayed by even the lowest organisms, and the evidences of intelligent design which they present. The second book reviews the scriptural evidences in favour of a future life, and is mainly an attempt to interpret and illustrate the symbolism under which information respecting that future life is conveyed. It is designed to combat materialism on the one hand, and spiritualism on the other. London: LONGMANS, GREEN, & CO., Paternoster Row.
