"... To the great advance that has been made in late years in the
accuracy and cheapness of processes of photographic reproduction is due
a further signal advantage that Dr. Wright's work possesses over his
predecessors'. He has thus been able to illustrate most of the natural
phenomena to which he refers by views taken in the field, many of which
have been generously loaned by the United States Geological Survey, in
some cases from unpublished material; and he has admirably supplemented
them by numerous maps and diagrams."--_The Nation_.
_MAN AND THE GLACIAL PERIOD_. By G. FREDERICK WRIGHT, D. D., LL. D.,
author of "The Ice Age in North America," "Logic of Christian
Evidences," etc. International Scientific Series. With numerous
Illustrations. 12mo. Cloth, $1.75.
"It may be described in a word as the best summary of scientific
conclusions concerning the question of man's antiquity as affected by
his known relations to geological time."--_Philadelphia Press_.
"The earlier chapters describing glacial action, and the traces of it in
North America--especially the defining of its limits, such as the
terminal moraine of the great movement itself--are of great interest and
value. The maps and diagrams are of much assistance in enabling the
reader to grasp the vast extent of the movement."--_London Spectator_.
