Prof. Evans on the Guernsey Oo. (O.) Meteor of May 1, 1860. 37 . 
no pains have been spared to collect and examine all the obser- 
vations from the west side, by personal communication with the 
witnesses. 
The conclusions which we have derived from the evidence 
may now be briefly summed up as follows. The course of the 
meteor was about 40° west of north. It was first seen over the 
81° 34’), at a height of 38 miles, nearly. Its velocity relatively 
to the surface of the earth, was from 8 to 4 miles a second.*

* Assuming that these stones are of extra-terrestrial origin, their velocity on en- 
tering the aliasigihees was greater than 4'9 miles per second, the velocity necessary 
to a circular orbit, Otherwise the major axis of their orbit would be less than 4000 
miles, and the orbit traced backward would again enter the atmosphere.—E
