78 Meteorological Journal for June. 



of nearly 40 degrees, and a point and a half to the eastward 

 of due North. 



In the afternoon of the 28th it was very sultry in London, 

 when the heat and sudden inosculation of the clouds brought 

 on a heavy thunder- and hail-storm, which did considerable 

 damage, particularly in its neighbourhood. 



Hay-making was commenced generally in this neighbour- 

 hood in the middle of the month ; and the hay, which was much 

 short of an average crop, was got in in a few hot sunn}' days 

 without rain. The wheat came into ear at the beginning of 

 the month, and will be fit for the sickle in the middle of July; 

 and there is every appearance for average crops. Fruits of 

 all kinds, particularly grapes, which bloomed well, have been 

 much improved in appearance by the warm weather. 



Lamentable complaints prevail in several parts of Scotland 

 respecting the effects of the solar heat and continued drought 

 upon the pastures and vegetation, and the great probability, 

 without rain, of a very scanty corn harvest. The effects of 

 the continued heat and drought, although they have been very 

 injurious to the pasture lands, are not, however, so alarming 

 in the South of England. 



The mean temperature of the external air this month is 

 nearly four degrees higher than the mean of June for the last 

 ten years, and within one degree and six-tenths of the hot June 

 in 1 822. The mean temperature of spring water has increased 

 nearly two degrees this month ; and the average evaporation 

 was one-fifth of an inch per day. 



The atmospheric and meteoric phaenomena that have come 

 within our observations this month, are, one anthelion, three 

 solar halos, two meteors, one rainbow ; sheet lightning ema- 

 nated from the clouds in the nights of the 26th, 27th, and 30th ; 

 and four gales of wind, namely, one from the N. and three 

 from N.E.
