go CtC(“‘ Objervations on Fire-Balts. 
The only inftance of a foft, frothy mafs beimg found i 
the place where a fire-ball fell is that which occurred in 
Lufatia, and the neighbouring diftriéts, on the 8th of March 
1796; and of which an account was given, in particular 
by Mr. Von Gerfdorf and Mr. Bauer, in the Lufatian 
Monat/chrift for April and May 1796. The fallen mafs ap- 
peared to be only a part which had been broke off, or which 
had, in fome meafure, dropped from one of thefe fire-balls. 
It is much to be lamented that the apparent courfe of this 
body, as far as could be done by the eye, was not obferved 
with fome accuracy, as has been the cafe with others men- 
tioned in my Treatife upon Iron Maffes, &c. that by calcu- 
lating their parallax their real path might be difcovered. 
Its velocity muft have been as great as that of many other 
fire-balls, which have moved at the rate of feveral German 
miles per fecond, and equal to the velocity of the planets 
in their courfes. This fire-ball, as was the cafe with that 
obferved on the 22d of July 1762, and with others, was 
firft vifible at a confiderable height above the horizon in the 
form of a fhining pot; moved along in a fomewhat fer- 
pentine direction, and increafed fuddenly to a confiderable 
fize: the duration of the whole phenomenon was about 
two feconds. 
It is much to’ be wifhed that fome one’ could give a more: 
accurate account of the fire-ball which, as I have been in- 
formed, fell a few years‘ago in the fea near Genoa, and oc- 
eafioned a ftrong ebullition in the water. 
I confider it as not fuperfluous to give here a fhort account 
of fome more inftances of ftones and mafles of iron which: 
have fallen from the atmofphere, as mentioned in my Effay,. 
becaufe fome, on account of my apparent paradoxical me- 
thod of explaining thefe phenomena, may have been pre~ 
vented from reading that work; and to take fome-notice of | 
the circumftances attending them, which, on. account of 
their great conformity, cannot be denied. A very remark- 
able
