On Thursday evening last, at 7 o'clock, I observed a very beau- 

 tiful rainbow, from Duke Street, extending in a brilliant and un- 

 broken arch in a westerly direction ; the south end spi'inging from 

 the west end of Queen Street, and the north end stretching to the 

 eastern extremity of Abercromby Place, compi'ising a space in the 

 horizon of 60° or 70°, and rising 16° or 18° in altitude. 



The prevailing colour was whitish, but occasionally the prismatic 

 colours shone out very distinctly, particularly the red and the blue. 



The weather was squally, with showers, and the bow appeared for 

 at least half an hour. 



Last night (Sunday evening) the same appearance was seen with 

 beautiful effect at 11 p.m., and continued for upwards of half an 

 hour.
