" 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- 
osed to have moved without any apparent cause, in the 
town of Salisbury in Connecticut. Finding that this ac- 
our anonymous correspondent, that there can remain no 
doubt of the main facts, or that they were produced by the 
same causes. 
lam 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 understoo . 
I have the honor to be, Sir, 
your very obedient servant, 
WM. MEADE.
