ARTHUR HOLMES
THE AGE OF THE EARTH
And Associated Problems. Illustrated

Gives us the result of the latest research into this field of enquiry. The radioactive minerals are shown to be recording their own age with the exquisite accuracy of a chronometer—their records checking physical, astronomical, and geological methods of computation.

PROF. A. W. BICKERTON
THE BIRTH OF WORLDS AND SYSTEMS
Illustrated
Preface by Prof. Ernest Rutherford, F.R.S.

A graphic account of the formation of new stars from the collision of dead suns or other celestial bodies. The theory throws light on many astronomical problems, and with its conception of an immortal cosmos, is of great philosophical importance.

PROF. SVANTE ARRHENIUS
THE LIFE OF THE UNIVERSE
2 Vols. Illustrated

“We can thoroughly recommend these volumes. The information is accurate, useful, and most suggestive. There are many for whom the first chapters of Genesis are a subtle allegory covering the profoundest truths, and we are grateful to the author for having set out this mass of facts.”—The Globe.
