With a supplemental chapter on Gladstone's "Dawn of Creation" and "Proem of Genesis' and on Drummond's "Natural Law in the Spiritual World." The object of this book is to give a clear and concise view of the principal results of modern science and of the revolution which they have effected in modern thought. The author does not pretend to discover new theories or facts, but simply discharges the useful task of presenting what has become the common property of thinking minds, which may interest those who lack time and opportunity for studying special subjects in more technical treatises.
