Eluor Spar in Tennessee.— Extract of a ti from H. H. 
Hayden, Esq. to the Ldito 
Baltimore, August 28th, 1821. 
This fluate of lime which I have sent you, was collected 
and brought t to me by a young gentleman | from Tennessee, 
who was g y about two years 
since. He informed me that it was found in Smith Coun- 
ty, Tennessee, where it was abundant: that it was known 
to the inhabitants by no other name than the blossoms of 
lead, of which it was considered a manifest indication : that 
considerable excavations had been made in search o 
in in fining which, the fluate of lime was discovered in isolated 
of various sizes, which were broken up and thrown 
From these he gathered the specimens 
Bhan: Sas 
a I have. 
As to its geological situation, T have no means of ascer- 
taining at present; but believe it to be in the primitive 
range, and if I remember correctly, he informed me that it 
occurred on the side of the mountain, and near the road 
leading to the Atlantic States. 
is substance he brought me perhaps a dozen pieces, 
all shales either whole or parts of cubes. The most 
predominant colour is that t of a beautiful violet or purple. 
ae of a yellow, and filled with brilliant pyrites. Amon, 
them is a specimen of two cubes united, (though mutilated, 
having the angles accuminated, and such as isr 
in the Abby Hauy’s work, plate 32d, fig. 87, and which 
he terms, ‘*Chaux flua tee Bordee.” OF this locality I have 
not the smallest reason to doubt, being well acanines “— 
“ Sry scour ;* and rend ork I think the mineral 
ost interesting of the kind that I have a pti from on 
eae of the United States. 
Crystalized Gypsum.—We are indebted to > William Lef- 
fingwell, Esq. for a very fine crystal from Ellsworth, pal
