ities from the size of a pea to that of a mustard seed ; ma- 
ny of these are filled with earth and with fibres of the turf 
through which it passed on striking the earth. The whole 
stone, when entire, was said to have weighed about four 
pounds. Its form is nearly spheroidal and its specific gravity 
The facts in relation to its fall, as I obtained them from a. 
friend who visited the spot on the 7th of June, (the day after 
I got possession of the stone,) are as follows. 
An overseer and several negroes were at work in afield 
belonging to a Mr. Matthew Winfree, about 9 o’clock on 
the morning of the fourth—an explosion was heard in the 
direction of Richmond towards the north east, which was 
at first mistaken’ for the report of a. cannon, ead in oe short 
time after, there was a noise which was thought at first to be 
the rumbling of a carriage on a neighboring stony road. 
In a few seconds however it was perceived to be rapidly ap- 
proaching, and presently after, seemed to be just over head, 
when if passed beyond, and ended by a sound resembling. 
the fall of a heavy body on the earth—the persons hastened 
towards the place from which the stroke proceeded, and af- 
ter considerable search, found a hole in the tarf which seem- 
ed to have been made ‘by the entrance of a ball; they dug, 
and got the stone above described. The stone had buried it- 
self about twelve inches—the distance of the hole from. the 
point where the persons were standing when the stroke was. 
heard, was found by measurement, to be two hundred and) 
sixty pac ” 
he sera on who gave the above account saw the hole the: 
third day after it had been made. The bed from which the 
stone was taken was entire when he was there; and of the 
size and shape of the body said to have been taken from it.
