A. Description of a large stone of the Linn Co., Iowa, fail of 
_ Feb. 25, 1847 : 
This stone, weighing twenty pounds, has lately come into my 
hands through the agency of Rev. R. Gaylord, of Hartford, lowa, 
the same gentleman who procured for me the specimens which 
were picked up at the time of the explosion of the meteor, and 
of which an account was given at a former meeting of the Asso- 
ciation, (see vol. iv, 288, 289, of this Journal. ) 
The following statement respecting it is from the Rev. Mr. 
Gaylord’s letter of July 3d, 1850. “It was found (in the sum- 
mer of 1847) in Hooshier grove by Abner Cox. He was in 
company with John Hollis, of whom I obtained two fragments 
three years ago. ‘They have had the stone two years or more, 
and by lying in the loft of a smoky cabin, it is somewhat dingy 
in appearance. This John Hollis is the man who ground up so 
much of the stones that were seen to fall, in order to get silver. 
He was the means, however, of the careful preservation of the 
present mass. Dr. Knight found they had the stone, and wrote 
me respecting it. : 
“'The three pieces into which it broke on striking the ground 
fit together exactly, so as to reproduce the original stone, with a 
complete coating over the whole, except on one side where sev- 
eral small fragments were broken out by the fall. ‘These were 
gathered up carefully and preserved by the finder.” : 
is stone is perhaps the most remarkable one thus far. de-— 
can the geologist look upon 
it without feeling almost cer- 
tain, that it once formed part 
of some extensive formation 
in the world from whence it 
came. 
Its dimensions will be best 
understood from an examina- 
tion of the annexed figure.

and the diagonal of 6 to the line gf, under 100°. The surfaces. 
and P’ are nearly flat, and agree in presenting a peculiar wavy, 
undulating surface and a deeper black color than belong to the 
other faces of the stone, a difference which appears to ¢
