guished without any explosion, several pieces of red matter, like 

 cinders, falling perpendicularly downwards, which were evident- 

 ly the burnt remains of the nucleus. — St Andrew's. On Sun- 

 day evening last, at about a quarter before nine, there was seen 

 in this city (St Andrew''s), a highly luminous meteor to the 

 south-east of the city. When it was first observed, it had the 

 appearance of a comet of transcendent brightness, having a nu- 

 cleus of about half a degree in diameter. It appeared to shoot 

 forth in a direction from SW. to NE. over a circular path of 

 about 35°, and gradually diminishing in magnitude, until it fi- 

 nally disappeared. What was perhaps most remarkable in this 

 meteor was, that in its orbit it did not present an unbroken vo- 

 lume of light, but appeared to throw out bright sparks in all di- 

 rections, resembling, in some degree, a sky-rocket. The same 

 appearance was observed at Cupar at the same time. — Bridling- 

 ton. Sunday evening 27th, about nine o'clock, a luminous 

 meteor of dazzling brilliancy was seen at Bridlington, for several 

 seconds, in a NNE. direction ; in disappearing, which might be 

 compared to bursting, it presented bright sparklings of a reddish 

 yellow colour. The night was beautifully clear and serene. 



7. RemarJcable Rainbow. — On the 18th May of this year, 

 1826, at six o'clock p. m., lightning appeared in the eastern 

 part of the heavens, and a little rain fell. There, where it was 

 darkest, I, and many of the inhabitants of Lengsfeldt in Eise- 

 nach, observed a very remarkable rainbow. We saw not only, 

 as is commonly the case, the feebly coloured interior rainbow, 

 and the darker coloured exterior rainbow, with all their transi- 

 tion of colours, but among these also the following threefold 

 repetition of them in the following order : — Most exterior rain- 

 bow, violet, blue, green, yellow, and red ; under a dark layer, 

 and below these with diminished intensity of colour, first the 

 common interior bow, with red, orange, yellow, green, blue, 

 violet ; then the following three ; purple, orange, green, violet ; 

 purple, orange, green, violet ; purple, orange, and finally a dull 

 green arched stripe. — Kdisten Archiv.
