3. Loam. In the newest alluvion along the Connecticut. 



4 Fuller'' s Earth. At the bed of iron ore in Kent. (Silli- 

 man.) 



64. Sulphur. This occurs pulverulent in small quantities 

 in mica slate, in Warwick, Shelburne, Conway, Sic. Per- 

 haps it proceeds from the decomposition of some sulphuret. 



65. Graphite. At Cornwall, Connecticut. (Brace.) Also 

 at Tolland. (Webster.) Also at Hebron and Sharon.

Mass.

68. Peat. In small quantities at Leverett, Mass.

 en by Prof. Silliman. (Am. Joura. Sci. Vol. HI. p. 74. 

 note,) no reasonable doubt can remain concerning this last 

 locality. 



70. Sulphuret of Silver. In Connecticut it is said to have 

 been found. (Cleaveland's Mineralogy.) 



71. J^ative Copper. At Bristol, Connecticut, in a vein 

 with the red oxide of copper. (Gibbs.) Also on the Ham- 

 den bills, a mass of about ninety pounds, adhering to the 

 rock. Also twelve miles from New-Haven near the Hart- 

 ford turnpike, a mass of six pounds in alluvial soil. (Silli- 

 man ) Also at Whately, IVJass in geest, on the limit be- 

 tween the primitive and alluvial soil, and about five miles
