The wind, during the whole continuance of the 
Antbeliwiy was almoft full N. as it had been the 
greateft part of the day. The weather was for this 
time of the year remarkably cold, and much colder 
than it had been for above a month before. There 
was even that morning a fmart white froft, and in 
fome places fmall collections of particles of fnow, 
though four or five of the preceding days were ex- 
ceflively hot. The wind was not high on the 24.th, 
but fomewhat fbarp. It was a bright fun-fhiny day, 
refembling a clear frofty day in December ; but not, by 
feveral degrees, fo cold. The following night the air 
feemed ftill replete with the fame fort of particles that 
had chilled it the day before. Hence will farther ap- 
pear the probability of the moft received opinion, rela- 
tive to the formation of this kind of meteors; which 
makes them to proceed from a multitude of minute 
icy or fnowy particles fufpended in the air, and either 
refraCting or reflecting the folar rays in fuch manner 
as to multiply the image of the fun. However the 
theory of Anthelia , for want of a proper number of 
obfervations, feems not yet to be arrived at fuch a 
degree of perfection as by every lover of phyflology 
could be delired. 
Inftances of Anthelia are extremely rare. I have 
hitherto been able to meet with only two of them, 
viz. that obferved near Dantzick ( i ) by Hevelius, 
Sept, dth, N. S. 1661. and that feen at Wittemberg 
in Saxony, Jan. 18th, N. S. 1738. a defcription of 
which was foon after communicated to the Royal 
(1) Johan. Hevel. Phanometi. Aer. p. 174, 176.
