Meteorological Observations. 7\\ 



clear blue sky, fully 15° high, and very slender, scarcely the diameter 

 of the sun. 



After the sun had set In a golden sky it became of a rosy hue, 

 brighter and broader at some places than others, as if the brightest 

 strata, or thin laminae of the horizontal clouds, reflected the sun- 

 beams most perfectly. It continued quite perpendicular, and about 

 half-past 9 o'clock, or 45 minutes after sunset, vanished gradually — 

 the last spot of it being 1 or 2 degrees above the horizon. About 

 an hour afterwards, when the moon rose, a pillar of light also ap- 

 peared over her, but fainter and shorter, and after 30 minutes when 

 she had risen a little above the horizon, a similar pillar appeared 

 below her, but they only extended about 3 or 4 diameters of the 

 moon on each side, having her diameter as a base, and tapering away 

 as they receded from her. This continued till 12 o'clock and pro- 

 bably much longer. 



I am told that the sun pillar was again very beautiful before sun- 

 rise next morning, about 3 o'clock.
