GUERNSEY COUNTY (OHIO) METEORITES. 



reach us at all, or if so, in the manner described by observers? 

 This question is a more important one to consider, as some 

 observers on similar data have calculated the elevation of mete- 

 orites where they were first heard to explode at one hundred 

 miles. 



As regards the size of the meteorite I have but to refer the 

 reader to my experiments made in 1854, and published 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 important 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 seemed to have 

 manifested itself; yet we

hear nothing of its fu- 

 ture career by reports 

 from observers north of 

 this, while its approach 

 from the south to this 

 point was noticed by a 

 number of observers. 



I need hardly state 

 that my own convictions 

 are that the meteorite 

 terminated its career in 

 G-uernsey County, and 

 that the group of stones 

 which constituted it were 

 scattered broadcast over 

 that county. Many have 

 been collected, and many 

 lie buried in the soil 

 to moulder and min- 

 gle their elements with 

 those of this earth. 



We come now to con- 

 sider the stones that fell and

were collected. Their number 

 was over thirty, and their places of falling have been plotted 

 with some care in the accompanying map (fig. 2.) 



The localities of twenty-four have been fixed with precision,
