18. Mr. Lyell and Mr. Murchison.—Mr. Lyell, the distinguished Eng- 
ES lish geologist, now in the United States, | having finished his course of 
___ lectures in the Lowell Institute in Boston, is warmly solicited by many 
: of the first citizens of Philadelphia, to repeat his lectures in that city ; 
~ we understand that he will comply with their wishes, and thus afford to 
= them, as he has done to the citizens of Boston, a rich intellectual treat. 
tS Mr. Lyell’s lectures, like his writings, are analytical ; unfolding the co- 
pious and accurate results of his own wide-spread and scrutinizing re- 
a? searches in many countries, he leads his audience forward through the 
i very paths which, for twenty years he has himself trod, in acquiring the 
knowledge whose rich stores he lucidly displays along with that which 
others have contributed. The elementary information which he im- 
parts, is the result rather than the text of his instructions. 
It were to be desired that this highly gifted philosopher were al- 
: lowed sufficient time to follow out this most instructive mode of teach- 
SS ing, until every department of the science shall have been fully iilus- 
3 When, in conclusion, a synthetical summary of general princi- 
ples, founded on the ample basis of his own detailed and exact observa- 
tions, combined with those of other geologists, would present in one 
perspicuous and convincing view, the grand elements of the science. 
His pictorial illustrations are ample, and some of them of magnificent 
dimensions and imposing splendor. Mr. Lyell’s writings present a 
model of skillful analysis of geological phenomena, conducted with 
logical accuracy and with great candor. _ They are > adorned bya style 
the highest order of scientific classical literature, and we trust that his 
active and successful researches will be continued for many years, 
cheered and aided as they are by one to whom, as the companion of 
a his travels, all his views and efforts are as familiar as they are inter- 
He now proceeds to the Southern States, as far as South Caro- 
_ lina and Georgia, and will return to give his course in Philadelphia in 
‘February. The Middle, Western and Northern States, and Canada, 
z will oceupy his spring and summer; and he will embark for England 
Ses _ in August, at the end of a year from the time of his arriv 
oe ? . Mr. Lyell’s visit is most acceptable to the American geologists, who 
~ @xpect his presence and assistance in Boston, at their meeting, April 
25, 1842, and we trust that the subsequent year may afford them the 
additional gratification of the presence of Mr. Murchison, than whom 
No oné is more eminent in active and successful labors in the common 
cause. This naa has just returned to England from a second 
visit to the Russian empire. ‘He has been to Moscow, and to the 
Asiatic flank of the Ural Mountains. His tour has been most success- 
ful, and he will be able to throw much light on the geology of @ great
