lower and lower through this stratum, becoming more and more 

 charged, and being for the most part stopped by the bed of earthy 

 lignite, has there given birth to the large masses above mentioned. 

 The stratum of earthy lignite being but a bad filter, the pyrites be- 

 come very scarce beneath, and soon (at two to two and an half 

 feet below it) disappears altogether.

Introductory Remarks. 



Through the medium of this Journalvol. I. pp. 21 4 and 31 7, 

 the public have been already favoured with the observations 

 of the Rev. Mr. Cornelius, on some portions of the southern 

 and south western States. At the request of the Editor, 

 facts and statements, derived from other sources, were ob- 

 tained by Mr. Cornelius ; and relating principally to parts 

 of the country on the Mississippi, winch that gentleman had 

 not the opportunity of seeing. This was the origin of Mr. 

 Bringier's memoir, which peculiar circumstances have pre- 

 vented our publishing till now. 



Although somewhat immethodical, it abounds so much 

 with interesting statements, that we have thought it better to 

 publish it, with some alterations and omissions, (agreeably 

 to the author's permission communicated with the paper,) 

 rather than to attempt a new digest of the subjects: for Mr. 

 Bringier appears to have contemplated little more than the 

 communication of inaterials, to be wrought into a different 

 form. — Editor.
