=THE GREAT ICE AGE, and its Relations to the Antiquity of Man.= By
JAMES GEIKIE, F.R.S. E. With Maps, Charts, and numerous Illustrations.
1 vol., thick 12mo. Price, $2.50.

"'The Great Ice Age' is a work of extraordinary interest and
value. The subject is peculiarly attractive in the immensity of
its scope, and exercises a fascination over the imagination so
absorbing that it can scarcely find expression in words. It has
all the charms of wonder-tales, and excites scientific and
unscientific minds alike."--_Boston Gazette._

"Every step in the process is traced with admirable perspicuity
and fullness by Mr. Geikie."--_London Saturday Review._

"'The Great Ice Age,' by James Geikie, is a book that unites the
popular and abstruse elements of scientific research to a
remarkable degree. The author recounts a story that is more
romantic than nine novels out of ten, and we have read the book
from first to last with unflagging interest."--_Boston Commercial
Bulletin._

The above is by far the most complete work on human physiology in the
English language. It treats of the functions of the human body from a
practical point of view, and is enriched by many original experiments
and observations by the author. Considerable space is given to
physiological anatomy, particularly the structure of glandular organs,
the digestive system, nervous system, blood-vessels, organs of special
sense, and organs of generation. It not only considers the various
functions of the body, from an experimental stand-point, but is
peculiarly rich in citations of the literature of physiology. It is
