442 PHILOSOPHICAL TRANSACTIONS. [aNNO 17 IQ. 



the night following a strange streaming of lights was seen in the air, which I 

 attended from 94- to 11, when a fog came on so thick, as to put an end to my 

 prospect. But during that whole time there ascended out of the E. N. E. 

 and N. E. a continued succession of whitish striae, arising from below ; and 

 after changing as it were into a sort of luminous smoke, past over head with an 

 incredible swiftness, not inferior to that of lightning ; and as it passed, in some 

 part of its passage, seemed as it were gilded, or rather as if the smoke had 

 been strongly illuminated by a blaze of fire below. Some of the striae would 

 begin high in the air, and a whole set of them subordinate to each other, like 

 organ pipes, would present themselves with more rapidity than if a curtain had 

 been drawn from before them ; some of which would die away where they first 

 appeared, and others change into a luminous smoke, and pass on to the west- 

 wards with an immense swiftness. And I am of opinion, that had it not been 

 for the moon, then 10 days old, and very bright, this for the time would 

 have been reckoned as considerable an appearance as that of the 6th of 

 March, 17 16. 



An Account of the same Appearance, seen at Cruwys Morchard in Devonshire, 

 Being part of a Letter to Sam. Cruwys, Esq. R. S. S. and by him com- 

 municated to the Royal Society. N° 363, p. 1 101. 



A further Account of the same Appearance as seen at Dublin. N°363, p. 1 104. 



An Account of another very considerable Aurora Borealis observed at Streatham 

 in Surry. By Mr. Thomas Hearne. N° 363, p. II07. 



It is deemed quite sufficient to print only the titles of these last three ac- 

 counts, as they contain nothing new, the appearances being the same as in Dr. 

 Halley's account preceding, expressed only in words a little varied from his. 



Nupera Observationes Astronomicce cum Regia Societate communicate. 



N° 363, p. 1 109. 



The astronomical obser\-ations were made by the Rev. Mr. Pound. They 

 describe two or three lunar eclipses ; but they chiefly relate to observations of 

 the near appulses of the planets to certain fixed stars, or distances from them 

 And are not of sufficient importance to be reprinted on this occasion.
