J. L. Smith on the Guernsey County (Ohio) Meteorites. 93 
height will be greatly augmented. I have found two persons 
living near Bear Creek, nine miles north of Marietta, who make 
statements closely corroborating that of Mr. Richardson. 
‘““D, Mackley, Esq., a lawyer of Jackson, Ohio, who at the time 
of the occurrence happened to be at Berlin, about six miles 
northeast from the former place, and seventy miles from the near- 
est point under the meteor’s path. He took pains to note all the 
facts as accurately as he could at that time; and he afterwards. 
returned to the spot in order to determine more definitely the 
points of the compass. His testimony, in answer to my interro- 
gatories is substantially as follows:— 
“The meteor first appeared to me at a point about 55° east of 
north. It moved northward in a line very nearly parallel with 
the horizon. When it disappeared it had described an are of 
about 15°. Jt was in sight about 6 seconds. Its altitude was 
about 30°. In regard to its size, I have since looked at the sun 
through a thin cloud, and I think the apparent diameter of the 
meteor was one-half that of the sun.” 
“These data give the meteor a height of 41 miles over the 
northern boundary of Noble county; a diameter of three-eighths 
of a mile; and a relative velocity of nearly four miles a second. 
The results agree sufficiently well with those before given.” 
emperature of the Stones.—Several of the largest stones were 
picked up ten minutes after their fall, and are described as being 
about as warm as a stone that had lain in the sun in summer. 
not rarer than the best air pump can produce, would reach us at 
all, or if so, in the manner described a observers? This 
‘lon 1s a more important one to consider, as some observers on 
fimilar data have calculated the elevation of meteorites, where 
they were first heard to explode, at one hundred miles.
