Meteorological Observations. 



[August, 



by a warm and hazy day. The two parhelia on the sides were 

 first observed, which slowly extending formed nearly the entire 

 arc of the central halo. The parhelion on the north side was by far 

 the brightest, and both were brilliantly colored. Soon after these 

 were formed, there appeared above the halo an arc apparently of 

 a parabola, also brightly irised. Finally and faintly there was 

 seen on the north side the arc of a large halo distinctly irised, 

 and the order of the colors were observed to be the same as those 

 in the smaller halo. The red of this, as of the smaller one, was 

 towards the sun, but the violet was its most conspicuous color. 

 During the whole continuance of this phenomenon, there was seen 

 by indirect vision a column of light extending upwards from the 

 sun and to a short distance below it. The irised colors of the two 

 parhelia were so bright as to attract general notice. The day 

 following was stormy, with a strong wind and driving sleet from 

 the west.
