4/4 Mr. Howard's Meteorological Journal. [Dec. 1818. 



REMARKS. 



Tenth Month. — 23. Windy. 24. Cold wind: some rain, evening. 29, a. m 

 misty. 



Eleventh Month. — 1. Foggy morning. 6. Foggy evening. 7. Very fine, 

 a.m. 10. Much wind, with heavy rain, in the night : about 10, p.m. the 

 clouds were passing over rapidly from SE. 11. Small rain, a.m.: gloomy, 

 p. m. 12. The moon at night rose gold coloured, and slightly veiled at 

 intervalii by the lighter modifications, with a mixture of haze : on these clouds 

 were afterwards displayed a succession of halos, strongly coloured with green and 

 red. I found by attentive observation that the halo in this instance, together with 

 a corona, which appeared constantly within it, was not formed in the substance 

 of the clouds above-mentioned, but in the haze, which was probably situated near 

 the earth ; for the colours of the halo always survived (though faintly) the passing 

 away of the white skreens of cloud by which at intervals they were set off and 

 made conspicuous. 13. A fine day : large Cumuli beneath Cirri, the latter ranging 

 at night from SE to NW very conspicuously : the moon again rose gold-coloured. 

 14. Rain, a.m.: and again in the fore part of the night, with much wind from the 

 southward. 15. Windy, cloudy, a.m.: lunar halo: rain in the night. 16. Wet 

 morning: fair, p.m., with Cirrus, Cirrostratus, and Cumulus. 17 — 20. Fair: the 

 sensible evaporation somewhat reinstated, with a brisk wind at the close.

* * * On the 26th of tenth month, a little before eight in the evening, I observed 

 from the neighbourhood of Lowestoft, Suffolk, a distinct commencement of Aurora 

 B ore alls in the north, in white streamers ascending to a considerable elevation, 

 which after a minute or two became converted into a still light : the latter, remain- 

 ing for an hour or two after, was at length obscured by clouds.
