158 Letter from Dr. Wm. Meade, 



Art. X. — Letter from Dr. William Meade, communicating 

 an account of a travelled stone, ^c. 



TO PROFESSOR SILLIMAN. 



Sir, 



In your Journal for June, 1822, an anonymous commu- 

 nication appeared, giving an account of certain rocks sup- 

 posed to have moved without any apparent cause, in the 

 town of Salisbury in Connecticut. Finding that this ac- 

 count though very circumstantially related, has been gener- 

 ally received with great incredulity, I beg leave to send 

 you the following very well authenticated statement, on a 

 similar subject, which I have copied from the Memoirs of 

 the Wernerian Society of Edinburgh for the year 1819, a 

 publication of great merit and respectability. 



You will perceive, Sir, that the circumstances attending 

 the movement of this Travelled Stone, as the journalist em- 

 phatically calls it, are so very similar to those detailed by 

 vour anonymous correspondent, that there can remain no 

 doubt of the main facts, or that they were produced by the 

 same causes. 



I am farther induced to send you this paper, from the 

 transactions of the Wernerian Society, not alone from its 

 establishing the fact of the occasional change of position of 

 certain large masses of stone, but from its tendency to ex- 

 plain some Geological facts, which as yet appear to be lit- 

 tle understood. 



I have the honor to be, Sir, 



your very obedient servant, 



WM. MEADE.

This stone is a large mass of conglomerate, being a con- 

 cretion composed of distinct irregular fragments of granite, 

 gneiss, quartz, and other rocks of the primitive series, ce- 

 mented together by a highly indurated and ferruginous clay
