found in speculative philosophy. Christianity in its appeal to historical evidence allies itself with modern science rather than with the glittering generalities of transcendentalism.

It is proper, also, that the author should from his own experience bear testimony that the engrossing cares of a clergyman, in the midst of which these studies have been pursued, need not dull one's interest in scientific study; and, on the other hand, that prolonged study of science does not of itself diminish one's respect for Christianity, and one's interest in the all-important work it is accomplishing for the world.

The first chapter was published nearly in its present form in the New Englander, October 1871. The next four chapters appeared at various intervals in the Bibliotheca Sacra; these have, however, been rewritten and enlarged to meet the demands of the present time. Chapter sixth is in the line of the author's original investigations, and will, with its illustrations, it is hoped, enlarge somewhat the boundary of human knowledge.

The last chapter, upon the Relations of the Bible to Science, might be longer; but it is probably best, in general, to treat the subject with

corresponding brevity. There is great danger of making too much of apparent conflict between science and religion. Before the scientific discoverer affirms a discrepancy to exist, he should ask if correct principles have been applied to the interpretation of the portion of the Bible in question; and the religious teacher may often evade a conflict by asking concerning an alleged scientific discovery, What of it? and then provisionally revising his interpretation of Scripture. He may be confident that the conflicts between science and religion will be concerning non-essential forms of expression; for science cannot penetrate to the depths in which the springs of religious activity are hidden. Unless he knows well the ground, the religious leader is unwise if he abandons his strongholds of defense, "to carry the war into Africa," and to wage an uncertain contest in a field with which he is not familiar.

Thanks are due to Mr. Geo. A. Bates of Salem, Mass., to Professor F. W. Putnam, Curator of the Peabody Museum of Archaeology in Cambridge, Mass., to Dr. C. C. Abbott of Trenton, N. J., and to Professor H. Carvill Lewis of Philadelphia, Pa., for the illustrations on pages 293, 297, 325, taken

Palaeolith from Abbeville, France,

The geological conditions under which the implements figured on this and the following page are found are very similar. For their relation to the glacial age see chapter VI.

from Dr. Abbott's recent, valuable, and exhaustive work on Primitive Industry of the Native Races of the Northern Atlantic Seaboard of America (Geo. A. Bates, Salem, Mass., 1881); and to Professor Dana for the cut on page 342 from the American Journal of Science. Of the five maps, II. is original; I. is adapted from a map by Hitchcock, in New Hampshire Geological Report, Vol. 3; III. from Cook's Geological Report of New Jersey for 1878; IV. from Lyell's Travels in America (First Series); and V. from N. H. Winchell's Fifth Annual Report on the Geology of Minnesota. Important additions from original information have been made to I. and III.

In addition to the cuts in the body of the chapter, two made specially for this work are here presented, facing each other that the reader may compare the rough stone implements found in New Jersey with those found in similar conditions in Europe. The one on page eight is natural size, and is No. 3034 of the Mortillet Collection from Abbeville, France. The one on page nine is shortened one inch in the cut, and is proportionally narrow, the original being 59 inches long, and 3 wide. This is No. 19723 in Dr. Abbott's col
