94 J. L. Smith on the Guernsey County (Ohio) Meteorites. 
As regards the size of the meteorite, I have but to refer the 
reader to my experiments made in 1854, and published in this 
Journal in 1855,* to show the perfect fallacy of calculating the 
, size of luminous objects by their apparent disks, and I shall have 
more to say on the same subject in a future paper. It is import- 
ant to note that the nearest approach of the meteor to the earth 
must have been in the northern part of Noble and in Guernsey 
counties, the point from which its most wonderful display seem- 
ed to have manifested itself, yet we hear nothing of its future 
career by reports from observers north of this, while its approach 
from ig south to this point was noticed by a number of ob- 
serve 
I ned hardly state my own convictions are, that the me- 
teorite terminated its career in Guernsey county, and that the 
group of stones which constituted it were scattered broad cast 
over that county: many have been collected, and many lie buried
