the United States ; of the immense quantities im- 

 ported into this country, the greater part comes from 

 the Bay of Fundy. Very little is brought from 

 France. Dr. Barton has been informed that very 

 considerable quantities of gypsum have lately been 

 discovered in the state of Virginia, upon one of the 

 head waters of the Staunton, and at the distance of 

 about twenty-five miles from Fincastle : also on the 

 Nine Mile creek, or outlet of the Owasko lake ; at 

 the falls of the Genessee river ; at the falls of Nia- 

 gara on the Canada side ;* at St. Mary's between 

 the Patuxent and Potowmack in Maryland; and in 

 the town of Marcellus in New York, according to 

 Dr. Mitchell. 



Specimens of a very fine gypsum, have also been 

 brought from about 150 leagues up the Missouri; 

 where it is said to abound. 



Fibrous Gyfisum is found in great quantities near 

 Lexington, Kentucky. 



Sky blue sulfihate of Strontian, or Celestine^ was 

 found some years since by Mr. SchUtz, in the neigh- 

 bourhood of Francstown, Pennsylvania, between la- 

 minae of a brownish red slate. f 



Suffihate of Barytes has been found in Sussex 

 county, New Jersey. It is of a very white colour, 

 and of a laminated structure. There is also a vein 

 of it on the west side of Paulin's hill, about six miles 

 from Sussex county, in the state just mentioned. A 

 large quantity of barytes also is found in the Sugar 

 loaf mountain, not far from the junction of the Mo-
