This volume contains the ripest fruit of the author's varied studies along the several cognate lines of evidence which converge with special power in recent times to shed light upon the foundations of Christianity. Among the subjects discussed are Limits of Scientific Thought, Paradoxes of Science, God and Nature, Darwinism and Design, Mediate Miracles, Beyond Reasonable Doubt, The Newly Discovered External Evidences, The Evidence of Textual Criticism, Internal Evidence of the Early Date of the Gospel, and Positive Results of the Cumulative Evidence. These chapters are an elaboration of the Lowell Institute Lectures delivered in Boston in 1896. GREENLAND ICEFIELDS, AND LIFE IN THE NORTH ATLANTIC.
