Volcanos. 1 07 



Scrope, Daubeny and others have given us accurate state- 

 ments of facts, and have reasoned upon them with direct 

 reference to the present state of physical science. 



To Mr. Scrope and Professor Daubeny we are particular- 

 ly indebted, for recent and very valuable observations and 

 discussions. Mr. Scrope published in 1825 his "Considera- 

 tions on Volcanos," and last year his " Memoir on the Geology 

 of Central France." Professor Daubeny has also very recently 

 published his " Description of active and extinct Volcanos." 



All these works are of great value, and as they have not 

 been republished in this country, and are probably possessed 

 by very few persons among us, it is our wish to make our rea- 

 ders acquainted with their character, which will be best done, 

 by giving some account of their leading features. 



Other engagements prevented us from doing this a year 

 since, with respect to the " Considerations on Volcanos," of 

 which we early received a copy from the author, and if we 

 now adopt the analysis of an Edinburgh Journal,* it is be- 

 cause we cannot present a better view of the work — a view 

 remarkable for its candor, its accuracy and completeness. 

 Some things may perhaps also be drawn from the " Journal 

 of the Royal Institution,"! and should there be occasion, we 

 may add some remarks of our own. 



It is our wish also, to present at a future time, some account 

 of Mr. Scrope's work on the extinct volcanos of France, &c. 

 and of Professor Daubeny's Lectures on Volcanos, but the 

 length of the present article will necessarily exclude a notice 

 of them from the present number. 



As this Journal has consisted, almost exclusively of original 

 American productions, we trust that the extensive quotations 

 which we shall now have occasion to make, will not be con- 

 sidered as a deviation from our plan, and that the high inter- 

 est and importance of the subject will prove a full justification 

 for occupying with it so much space, and for the postpone- 

 ment of some original articles. 



While we entertain and express the highest respect for the 

 authors of the works alluded to above, we wish to be under- 

 stood, to attach the principal value to their precise, methodi- 

 zed, and copious statements of facts ; with most of their con- 

 clusions we do indeed, fully agree, but there are theoretical
