THE METEOROLOGY OF ENGLAND 
DURING 
THE QUAJH'ER ENDING JUNE 30, 18G0. 
By JAMES G L A I S II E E, Esq., F.R.S., 
EEC. or THE BltlTISH METEOKOLOalCAL SOOIETV. 
The cold weather ■which set in on January 25, and which was 
prevalent to the end of the last quarter, continued, excepting the 
19 days following May 8, till the end of the present quarter. 
The mean daily deficiency of temperature for the 38 days begin- 
ning April 1 amounted to 3j°, and for the 34 days ending June 30 
was as large as 4|-° ; the average daily deficiency for these 72 days 
was 3J°. The remaining 19 days, viz., from May 8 to May 26, 
were warm, and their temperatures were daily in excess of the 
average to the amount of 3-|°. 
Both the days and nights in April were remarkably cold, and to 
an almost equal amount ; in May both were somewhat warmer than 
usual ; and in Juno botli were cold, particulai'ly the days, the 
mean temperature of which was lower tlian in May, although it is 
usually higher to the amount of 7 degrees. 
The temperature of April was 3°-G in defect ; that of May l°-0 
in excess ; that of June •±°-4 in defect, as compared with the averages 
of the preceding 19 years. The month of April was colder than 
any April since the year 1839, and we must travel back to the year 
1821 to find so cold a June. 
The mean pressure of the atmosphere in April was a little above, 
in May a little below, and in June much below, the average. 
The range of the barometer readings at extreme southern stations 
was 1*2 inch in Aj^ril ; 1-0 inch in May; and somewhat less than 
an inch in Jime; these values gradually increased on going nortli- 
ward to 1-9 inch in April ; to 1-3 inch in May : and somewhat more 
than an inch in June at extreme northern stations. 
The temperatiire of the dew point in April was 3^-4 in defect, 
being very nearly the same in amount as that of the air ; and there- 
fore the degree of humidity was of its average value ; in May it 
was 0"8 in excess, being somewhat less than the excess of tempera- 
ture of tlie air, and the air was slightly drier than the average ; in 
June its defect was l°-3, whilst that of the air was 4°-4, so that the 
air in June was remarkably humid. 
The fall of rain at Greenwich in April was 0*8 inch in defect ; in 
May 1-8 inch in excess, and in June 3-9 inches in excess. The total 
Ml was 10'7 inches, being 4-9 inches over the average for this quarter. 
Gales of wind have been frequent during the quarter. 
The mean temperature of the air at Greenwich, for the three 
months ending May, constituting the three spring months, was 
4,j°-9, being O^'o below the average of the preceding 89 years.
