was in the North, and a little to the Weft. There 
were neither Pyramids, nor luminous Streamings, fo 
common in Aurora Bore ales ; nor even the lcaft 
Appearance of the horizontal black Cloud at North. 
The following Day was equally dark with the pre- 
ceding, yet without the leaft Remains of the Rednefs. 
Such was the Face of the Heavens at Wittemberg , 
and in the Neighbourhood. And, foon after, the 
public News gave an Account of the like ‘Pheno- 
menon being feen at Vienna , Venice y Mantua , Flo- 
rence , Rome , and fome other Places. At Vienna 
the greateft Brightnefs was obferved at s>h. 15'. The 
mod enlightened Parts were the North-weft and 
South-fouth-eaft 5 and there were fome Returns of 
the Brightnefs on the 17th and 18th. But in Italy t 
at Mantua , Florence y and Rome , the Rednefs was 
accompanied with lucid Columns and Pyramids. 
And from Rome y in particular, they write, that this 
Aurora Borealis exceeded in Brightnefs all thofe that 
had been hitherto obferved. From thefc Obferva- 
tions it is no difficult Matter to deduce the Caufes of 
thefe red Lights. 
That this Aurora Borealis , on the 16th, was a very 
confiderable one, appears both by the great Expan- 
fion of the luminous Matter from its Rife in the 
North towards the South, and by the Return of the 
Brightnefs feen at Vienna on the fubfequent Days. 
At Mantua the Northern Light reached the Zenit h t 
and it is more than probable it did fo in our more 
Northern Horizon: Wherefore, as the Matter was 
collected at th z Zenith y the Light was refle&ed thence 
to all Parts of the Sky. But as the lower Region of 
our Atmofphere was at the fame time overfpread
