by publishing the following recommendations, which form only a part of 

 a very numerous selection. He trusts that these unsolicited evidences of 

 his competency for the task he has luidei'taken, will have a tendency to un- 

 deceive those, who, not knowing him, hdfve been induced to hsten to the per- 

 sons who are interested in injuring the success^of his Journal. 



Until further notice, the publication and distribution of this Journal, will be 

 superintended by the Editor, to Vi'hom correspundents will please, in future, 

 address all their communications. ' 



The publication of the second volume will commence on the first of July 

 next. It has been found necessary to enlarge it. It will contain at least 100 

 more pages, with additional plates and illustrations. The price to subscribers 

 will be five dollars, payable in advance.

COMMUNICATION FROM THIE PRESIDENT OF THE GEOLOGI- 

 CAL SOCIETY OF LONDON, AND OTHER NATURALISTS. 



London, June 18, 1831, 



My Dear Sib, — We, your undersigned friends in England, are happy to 

 learn that you propose to establish a new periodical work in the United 

 States, which, in embracing all subjects connected with the natural history 

 of America, is to be specially devoted to the accumulation of geological 

 facts and phenomena. ^ * 



Knowing your zeal and ability, we have great hopes that a work so directed, 

 will meet with every encouragement in yoin- country, and we are certain that 

 it cannot but be of service to the cause of science in general. 



We shall at all times be desirous of aiding you with any communications 

 in our power, and we subscribe ourselves. 



Yours very faithfuHy, 

 RoDEnicK Impet MtTRCBis^ON, President of me Geological So- 



ciely of London.

P. S. — I cannot refrain in particular on my own part, from expressing the 

 desire which I feel for the appearance of the proposed publication, as likely 

 to conduce, in the most important points, to the effective progress of geology ; 

 to ascertain in detail the suite of formations, and the series of organic re- 

 mains distinguishing them in a new continent, so widely separated from the 

 old, and embracing such a range of various climate :■ so to compare the phe- 

 nomena with those of Europe, lias ever appeared to me the most material 

 desideratuqn in geology ; for we may I>e s\n-c tiiat any analogies which are 

 common to localities geographically so distant, and placed under physical 

 conditions so distinct, are, in trutli, an.alogies belonging generally to the 

 whole globe ; and thus we shall obtain data adequate for the foundation of a 

 general geological theory. 



Well acquainted with the attention you h.ivc paid to the formations on this 

 side the Atlantic, I am convinced that the execution of this task, cannot fall 

 into more competent hands. VV. D. Contbearr.
