standard books upon those subjects. This Manual has had a
very great sale in England, and its successive editions have
kept pace with the steady progress of geological science. To
the last edition, new and important pages have been added,
containing the latest discoveries In geology. This study has
never before received so great attention as at present, and in
no other country can it be studied so profitably and with such
practical results as in this."--_Providence Journal._

"This is a standard work, on one of the most wonderful of
modern sciences. In connection with the "Principles of
Geology," by the same author, it gives a complete survey of
the science at its present stage of advancement. We commend
these works to the serious attention of those fossil
theologians who esteem it their duty to bring the Bible, if
they can, into conflict with the inductive sciences, and who
think that their interpretation of Genesis is a sufficient
reply to all the inductions of Geology."--_Recorder._

"The author of this volume is among the most eminent of
geologists, and is well qualified to make an exposition of the
science. This "Manual" is not intended as an epitome of
another work, "The Principles of Geology," but occupies a
distinct place, the "Principles" containing a view of the
_Modern_ changes of the Earth and its inhabitants, while the
"Manual" relates to the Monuments of _Ancient_ changes. The
author recommends to the student of geology who wishes to
examine his works, to commence with the "Principles," a new
and thoroughly revised edition of which is just about tube
issued by the Publishers of the present volume. "We are not
among those who apprehend injury to the cause of Scripture
truth, by the study of this science, and we only wish it were
more generally and thoroughly investigated by sound minds. It
is imperative on all theologians, and those designing to
become such, to make this a branch, of study, and thus to be
prepared to defend the truth when it is assayed, as it has
been by men of science. The truth has nothing to fear, but
every thing to gain even from scientific
investigation."--_Observer._
