i. Tue preceding specimens of sulphur, being such as 
were formed in the dry way, or by means of fire or subter- 
raneous heat. Here follow some which have been produced 
in the moist way, or by means of water. 
(a) Native sulphur, from West Point, Orange county, 
New-York, not far from the Military Academy. The ad- 
mixtures of foreign ingredients render it blackish, like an 
Ethiop’s mineral. 
(6) Sulphureous sediment, from the trough of a spring, 
three miles west of Athens village, New-¥ork.—Seeley. 
(c) Sulphureous depositions, in proper form, on moss 
and leaves; from the spring at Clifton, Phelpstown, On- 
tario county, New-York.—Adriance and Miller. 
(d) Another sample of the deposit, after artificial evapo- — 
ration ; brimstone, leaves, &c., as they had consolidated in 
a cup.—The same.
