Meteorological Observations for June 1828. 159 



and three till nearly six o'clock in the morning of the 15th, the weather 

 was very awful here ; the lightning, which was chiefly forked, flashed vividly 

 at short intervals ; its colour was dark-red ; it continued a long time in the 

 zenith, and the explosions were so near, that the rushing of the adjacent 

 air into the displacement to restore its equilibrium, shook the foundations 

 of the houses. There were two winds at the same time ; viz. a strong gale 

 next the earth from due North, surmounted by a slow moving current from 

 S.E. as ascertained by the black thunder-clouds which the latter wind 

 carried with it : by the inosculation of these winds, and clouds of unequal 

 temperatures from nearly opposite points of the compass, the lightning was 

 generated, and was awfully grand for upwards of two hours. No damage 

 was done by the storm in this neighbourhood, but it was severely felt in 

 the upper part of the country. The same morning between four and five 

 o'clock, just before the heavy rain came on, a beautiful double rainbow ap- 

 peared in a large nimbus to the westward ; the arc of the exterior bow ex- 

 tended from about S.S.W. to W.N.W. The electric fluid which accom- 

 panied the recent thunder-storms in this county was very powerful, having 

 killed several men and horses. 



On the 20th, about 5 o'clock in the afternoon, an anthelion appeared 

 in the eastern prime vertical, opposite to and 120 degrees distant from the 

 sun. This rare phenomenon presented itself in a light brown cumulostratus 

 cloud, from which it was distinguished by its circular silvery colour, which 

 repeatedly contracted and expanded according to the effulgence of the sun. 

 It continued in sight nearly two minutes, by which time the cloud had 

 moved oft' too far to the north-east to exhibit the sun by reflection. 



The 28th and 29th were hot sunny days, the thermometer in the shade 

 in the afternoons being at 80° and 81°, and in the sun's rays at 106°. 



The mean temperature of the external air this month is 2£ degrees higher 

 than the mean of June for the last twelve years. 



The atmospheric and meteoric phenomena that have come within our 

 observations this month, are one anthelion, one parhelion, four solar halos, 

 two double rainbows, lightning and thunder on four different days ; and 

 eight gales of wind, or days on which they have prevailed ; namely, one 

 from the North, one from the North-east, one from the East, three from 

 the South-west, and two from the West.
