 whose lectures during' the pa.st winter, wcie exceeding-ly popuiivr, has com- 

 menced a publication under this title. 'Ihe first number is I'ich in tiie variety

Journal of Geolifry. The supervisloii of a gentleman so favonraljly known 

 to the public as i\lr. Featherstonhaug'.i will doubtless secure for the work an 

 ample patronage. — Connecticut Mirror. 



The Monthly American .Tournulof Geology and Natural Science is conducted 

 by Mr. Keatheistonliaugh. The well esuiblished reputation of the editor 

 wdl doubtless secure an extensive and permanent support. — Boston Travilltr. 



Monthly American Journal of Otology. A highly valuable and interesting 

 periodical bearing this title, has been commenced in Philadelphia by Mr. 

 Featherstonhaugh. He has deservedly acquired a high reputation for scien- 

 tific attainments, and his style of communication is strikingly puic and ap- 

 propriate. — Miner's Journal. 



We have received the first numbers of the Monthly American Journal of 

 Geology and Natural Science. Mr. Featherstonhaugh has a wide notoriety, 

 and the amount and value of his scientific attainments are as well known to 

 the public as to us. We feel willing to trust to the reputation of the editor 

 for tJie merit of the publication. — Connecticut Journal. 



American Geology. The geology of the United States has been so imper- 

 fectly explored and determined, tliat we confess it would have given us the 

 most sincere pleasure, had the late Mr. Girard, of Philadelplii.i, left among 

 his princely legacies the interest of $200,000 forever to be expended in geo- 

 logical explorations and surveys. This sum of money would have enabled 

 two or three scientific gentlemen to enter upon a systematic and efficient 

 course of labor that might devclope the geological Ireiisurcs of our gigantic 

 continent, and add incalculably to the perfection and beauty of this noble 

 science. The intimate connexion between geology and mineralogy and agri- 

 culture would have justified a bequest of this magnitude, sufficiently guarded 

 by trustees or some scien:i;'.c institution. The geology of America, like the 

 features of the continent, is rich and grand and di^■ersified, almost beyond 

 comparison — and yet we have but one journal devoted principally to this 

 science in the country. We refer to "the Monthly American Journal of Ge- 

 ology," published in Philadelphia, and edited by the accomplished and per- 

 severing G. VV. Featherstonhaugh, Esq. This periodical is in the first year 

 of its existence, yet we hope it has made a beginning that shall lead to results 

 as auspicious as its field of labor is rich and productive. — Badger's Mcssetigu: 



Journal of Geology. AVe have, at diflcrent times, lent our humble efforts
