Dsar Sir, 



RECEIVED your letter of the 3rd of Oct and have, agreea- 

 bly to your request, put up a set of the specimens taken 

 from the diiferent basaltic walls in this neighbourhood, illus- 

 trative of their formation. You will probably receive them 

 shortly by one of the coasting vessels from Wilmingtan to 

 New-York. You also expressed a wish that I would com- 

 municate such informatlonj connected with their history as 

 might be in my possession ; and referred me to several Vols* 



of the Medical Repository, for what had beeo vrritten upon 

 the spbject. J had read and compared the descriptions 

 given by the Rev, Dr. Hall, and the Rev. Zach. tewis, 

 with the walls themselv^esj and found them In many particu- 

 lars correct; and I cannot perbaps better convey my ovrn 

 ricvvs than by quoting occasionally from tbena. 1 shall not 

 however attempt to discuss with these gentlemen, the ques* 

 tion of their ongin or nature : it is a matter so completely 

 Vol, V-....No. L I
