Meteorolugical Observations. 2lo 



', .'Ct differ from thope above ; and although the Polythalarnhi arc still 

 abundant, and many of the species apjjear to be the same as in tlie 

 strata above, yet they are less easy to observe on account of the 

 greater compactness of the marls, and the adherence of crystalline 

 calcareous particles to the shells. 



" 6. 'I'he marls which you sent from the Cooper River, 35 to 38 

 miles above Charleston, also abound ni Polythalamia, and so many 

 of the species are identical with those found beneath Charleston, that 

 they most proljably belong to the same formation. This place on 

 the Coojjer River may be the outcrop of the very slightly inclined 

 beds which exist under Charleston. [In this conclusion Prof. Bailey 

 is correct. — J. L. S.] 



" 7. The Polythalamia, to whose labours South Carolina owes so 

 large a portion of her territory, are still at work in countless thou- 

 sands upon her coasts, tilling up harbours, forming shoals, and depo- 

 siting their shells to record the present state of the sea-shore, as their 

 predecessors, now entombed beneath Charleston, have done with re- 

 gard to ancient oceans. The mud from Charleston harbour is filled 

 not only with beautiful Polythalamian shells, but is also very rich in 

 siliceous infusoria." — Extract of a letter from Prof, Builoy to J. L. 

 Smit/i, in Silliman's American Journal, Jan. 1845.
