XII. Meteorological Observations for Portions of the Years 

 1836 and 1837, made at Bermuda; and a Notice of an 

 Aurora Bor calls seeti in low Latitudes, By Lieut, -Col. 

 A. Emmett, Royal Engineers, 



To the Editors of the Philosophical Magazine and Journal, 

 Gentlemen, 

 nPHE great attention now given to meteorology induces me 

 -*■ to forward for the Philosophical Magazine asummary of the 

 observations taken by me within the period of twelve months*. 

 Every attention has been given to their accuracy ; and from 

 the character of the instrument-maker, Mr. Newman, I think 

 they may be received with confidence. I am well aware that 

 the observations of twelve months are insufficient for establish- 

 ing'many data, yet there are two or three points which merit 

 attention, particularly that of the horary changes. 



I shall not at present trespass further on your pages than 

 to notice that a most splendid aurora borealis was seen here 

 on the 25th of January, as also even down to the tropics, re- 

 specting which I transcribe an extract from the journal of 

 Captain Willis of H.M.S. Cruiser, which he was kind enough 

 to send me from Jamaica : 



" In lat. 22° north, long. 57° west, at 8 p.m., the aurora 

 borealis was observed very brightly ; it began at 8 by a red 

 flush suddenly spreading itself over a great part of the 

 northern hemisphere, extending in altitude to about S0« ; then 

 a number of streamers showed themselves shooting upwards 

 with great brilliancy. They continued about fifteen minutes, 

 then ceased, leaving that part of the sky for a time blood red." 



The appearance here was very similar, but more extensive 

 and of longer continuance. 



I remain, &c. 



Bermuda, Julv 1 1 , 1837. A. Emmett, 



Lieut.-Col., R. E. 



P.S. This aurora appears to have been seen over a large 

 extent of North America. 



♦ Lieut.-Col. Enmiett's observations for the period from July 1 to Sep- 

 tember 30, 1836, having already appeared, in the paper prepared by Dr. 

 Dalton, inserted in our last volume, p. 44.0, we have omitted them in the 

 tables which follow; retaining, however, the means for the entire six 

 months, from July 1 to December 31, 1836.— Edit.
