Localities of Minerals. 
Art. V.—Localities of Minerals. 
To the Editor of the American Journal of Science, $c. 
New-York, Dec. 21, 1818. 
Dear Sir, 
Ir is desirable that some mode should be adopted by which 
the public may become acquainted with all the Vew American 
Localities of Minerals, as they are discovered from time to time. 
With deference I would suggest, that in each number of yout 
Scientific Journal, new localities might be recorded in alpha 
betical order, for present information and future reference. 
The following localities, which have come under my obser- 
vation, and which are probably not noticed in any work, are a 
your service. :
