Meteorological Observatioiis fo7- June 1831,. 159 



General Observations.— This month has been alternately dry and showery; 

 but from the powerful influence of the solar rays in June, the showers of 

 rain were seasonable, and aided the growth of the crops. 



In the moruing of the 9th at nine o'clock, a large double halo appeared 

 round the sun, with two parhelia outside of the exterior halo; the inner 

 edge of the interior halo was twenty degrees distant from the sun's centre, 

 and the inner edge of the exterior halo was 22° 35', while each of the 

 parhelia was twenty-six degrees from his centre, and they had white trains 

 seven or eight degrees long. 



In the night of the 12th there was sheet-lightning from ten P.M. till 

 three A. M.^ when it was accompanied with thunder and heavy rain; the 

 lightning, which was vivid and of a blueish colour, had nearly ceased to dis- 

 charge itself from the clouds when the rain came on. 



In the afternoon of the 14th two parhelia appeared at the exterior edge 

 of a large solar halo, from half-past four P.M. till sunset. 



Hay-making began here about the middle of the month : the hay was ricked 

 in dry order, and was found to be average crops, and more in some places. 

 The wind having prevailed nearly the whole period from the western side 

 of the meridian, there has been no arid, but rather a moist air, which, with 

 much sunshine, has had a beneficial efFect on the growth of the wheat, 

 so much so, that with a fortnight's tine, dry weather it would be fit for the 

 sickle. Comparatively speaking the barley and oats are rather backward 

 in growth, yet, like the wheat, they have a promising and plentiful ap- 

 pearance. 



The mean temperature of the external air this month, is equal to the 

 mean of June for many years past. 



The atmospheric and meteoric phaenomena that have come within our 

 observations this month, are, four parhelia ; one lunar and six solar halos ; 

 four meteors ; one rainbow ; thunder on one day and lightning on two days; 

 and five gales of wind, namely, four from the South-west, and one from 

 the West.
