34 Prof. Evans on the Guernsey Co. (O.) Meteor of May 1, 1860. 
rately on the spot, with a view to publication. I may add also 
ote I have subjected both of these witnesses to a close examin- 
Mr Welles’ place of observation was in the state of Virginia, 
(lat. 39° 17’, lon. 81° 24’), about three miles east of pbertaic sf 
His testimony is as follows. e saw the meteor thro 
opening in the clouds, first appearing about 50° east of coi ; 
and disappearing about 20° east of north. It was in sight about 
three seconds. Its altitude when 35° east of north was about 
65°. Of this he is most confident. When asked at what altitude 
its visible oo produced would cut the meridian to the north of 
hi from 50° to 55°. It is important to observe that 
. Welles judgment ¢ as to angles 1 18 to be wn relied asec 
: ofiaags is as follows. He saw a brilliant meteor pass over a 
oe space from about = east of north to about 40° east of 
th. It was ea nearly parallel with the horizon. When 
sb os altitude ¥ was about 30°; at its disappearance 
7 tw ower. It was in sight about six see- 
nds ge ee 8 account of the manner in which he esti- 
ted the angles serves to strengthen confidence in his penne 
_ He says that as nearly as he could judge, the meteor appeared at 
_ one third of the distance from the horizon to the zenith, and the 
are which it described, when projected on the horizon, would be 
one half the altitude. He states also that he visited "the place 
again in order by determine, as accurately as possible, the points 
of the compas 
In order soe to make a first approximation, let us assume that 
the path of the meteor, when projected on the earth, would pass 
through New Concord, (lat. 40° 1’, lon. 81° 45’), on either side of 
which the heaviest stones fell. The bearing of this line, as 
shown by the direction of the route along which the stones were 
scattered, by the direction in which different pieces are ascertained 
by Profs. Andrews and Smith to have reached the ground, and 
by the direction to which the successive reports attending their 
fall receded, must have been nearly northwest. Let us then 
suppose, by way of trial, that it was exactly northwest. Mr. 
Mackley saw the meteor from Berlin in a northeast direction. 
. Now these two directions being at right angles to each other, it 
peers that its real path was nearly parallel with the earth’s sur- 
face; for otherwise its apparent path could not, under the given 
conditions, have been nearly parallel with the horizon, as Mr. 
Mackley declares it was. Ié follows also that its height above 
e earth was not far from 40 miles; for the altitude given by _ 
Mr. Mackley is from 28° to 30°, and the distance northeast from s
