ON 
THE METEOROLOGY OF ENGLAND 
DURING 
THE QUARTER ENDING JUNE 30, 1859. 
Bt JAMES GLAISHEE, Esq., F.K.S., 
EEC. OF THE BBITISR HSTEOBOLOGICAL EOCIEIT. 
Till the 11th of April the air was warm, being 7° above the 
average ; till May 23rd for the most part cold, the average daUy 
defect being 2 J° nearly ; and fi-om May 24th to the end of the 
quarter it was almost always warm ; the average daily excess of 
temperature being 3° nearly. 
Till April 11th the wind was from the S.W., passing at the rate 
of 170 miles daily; to May 23rd it was mostly X.E., with a daily 
horizontal movement of nearly 100 miles; till June 20tb it was 
K.E. and S.E., and S.W. from June 21st till the end of the quarter. 
The average daily movement for these last 37 days was 55 miles. 
The mean temperatui-e of April was 0°*1, of May 0^-3, and of 
June 2°"3, above the average for the last 18 years. Both night 
and day temperatures in the months of April and May were very 
nearly of their average value; and both these elements were 
high in June, and therefore the days and nights in this month were 
warm. 
The mean temperature of the dew-point was below its average value in 
April, and above it in May and June. The mean degree of humidity 
of the ail- in April and May was veiy nearly of its average value, 
and was in excess in Jime. The aii-, therefore, in June was some- 
what humid. 
The reading of the barometer was below the average in April and 
•June, and somewhat above it in May. It increased from April to 
May at all places, the increase being greatest at northern stations. 
The fall of rain in the quarter was nearly that of its average. The 
deficiency from the beginning of the year is li inch. The deficiency 
in the years 1854, 1855, 1856, 1857, and 1858, amounts to the 
average fall of one year, viz. 25 inches. From a careful examination 
of the faU of rain from the year 1815, it would seem that the annual 
fall is becoming smaller, and that there is but little probability that 
this largo deficiency will be made up by excesses in future years. 
The mean temperature of the air at Greenwich for the tkree 
months ending May, constituting the tliree Spring months, was 
48<^-7, being 2°-'6 above the average of 88 years.
