HAVE RECENTLY PUBLISHED NEW EDITIONS OF 
I. 
A MANUAL 
OF 
ELEMENTARY GEOLOGY; 
Or, the Ancient Changes of the Earth and its Inhabitants, 
AS ILLUSTRATED BY GEOLOGICAL MONUMENTS. 
BY SIR CHARLES LYELL. M. A., F. R. S., 
Author of''’ Princiyles of Geology <&c. &c. 
Reprinted from the last London, Entirely Revised Edition. Illustrated with 500 Wood-Cuts, 
One large 8vo. Price $1 75. 
“ The author of this work stands in the very front rank of scientific men, and his works upon 
tlie sciences, to which he has devoted his great powers, and his indefatigable study, are the 
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 connec 
tion 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 con 
flict with the Inductive sciences, and who think that their interpretation of Genesis is a 
sufficient reply to all the inductions of Geology.” — Recorder.

PRINCIPLES OF GEOLOGY ; 
Or, the Modern Changes of the Earth and its Inhabitants. 
New and Entirely Revised Edition. Illustrated with numerous Maps, Plates, and Wood- 
Cuts. 1vol. 8 VO., pp. 846. $2 25. 
“Limited space precludes our enlarging on the contents of this rich volume, exhibiting the 
history of our planet and the theory of our species, of the duration of past time, of igneoxis 
force and its effects, and of those causes producing the various phenomena disporting over the 
ever-changing surface of our globe. 
Geology is intimately related to nearly all the physical sciences, and it were therefore 
desirable that the student be well versed in chemistry, mineralogy, zoology, botany, and in 
every branch embracing the subjects of organic and inorganic nature. Cosmogony, or the 
origination of the earth, with which this science has been often confounded, is a distinct theory 
and in no wise concerned with geology .’’ — The Cultivator.
