NIL Aa Account of the Meteor of the 182h of Auguft, 1 783. In 
_a Letter from Richard Lovell Edgeworth, E/g. FR. S: to 
‘Sir Jofeph Banks, Bart, P.R.S. a 
Read Jan. 15, 1784. 
MEAR SIR, ‘Edgeworthflown, Mullingar, Ireland. 
T half paft nine in the evening of the 18th of Auguft, f 
faw the meteor which has been obierved in fo many 
different places. | 
ts fize appeared to be about one third of the moon’s diame- 
ter; and it moved from the noth with an equable velocity, at 
an elevation of ten or twelve degrees, and in a line parallel to 
the horizon. 
It was vilible during ten or fifteen feconds, and feemed to be 
of a parabolic figure, with a luminous tail, twenty or five and 
twenty of its diameters in length. 
It exhibited the moft vivid colours; the foremoft part being 
of the brighteft blue, followed by different’ fhades of red. 
Twice during its flight it was eclipfed or extinguifhed, not 
gradually, but at once, immerging and emerging with undi- 
minifhed luftre. 
I fhall not venture to trouble you with any conjectures upon 
the nature of this phenomenon, as it is probable, that the 
fubje&t has been fully difcuffed long before this time by your 
friends in London. Iam, Gc. 
Sept.s, 1783. RicHARD LovELL EDGEWORTH.
