24th, and the lowest 20°-8, on the 25th. Owing to the 

 cloudy skies, the solar radiation maximum was never much 

 above the corresponding shade value. Only 24 hours sun- 

 shine was recorded. The precipitation, chiefly in the form 

 of snow, was under an inch. There was a fog on the 10th 

 and 11th. 



Fehruary. — The cold weather of January continued to 

 prevail during the ,first twelve days of February, but the 

 depression of temperature was more apparent in the day than 

 in the night values, the diurnal range being thus very small. 

 The second half of the month was mild and stormy, with a 

 good deal of rain during the last week. During the last 

 fortnight the weather was sunny. A strong gale blew on 

 the 25th, on which evening, at 9 p.m., the sky was cloudless, 

 but the air was saturated, rain falling heavily. No frost 

 was registered after the 12th. 



MarcJi. — Very unsettled stormy weather prevailed through- 

 out March, with little frost. The mean barometric pressure 

 was only 29*481 inches, the lowest since February 1885, 

 while there were only three months since 1769 with a lower 

 value. Only for a few hours on the 7th and 8th did the 

 sea-level pressure exceed 30 inches. The winds were almost 

 wholly from the south and west. Kain fell on 24 days, 

 the only really fine day being the 29th. Snow fell on the 

 4th, 10th, 28th, 30th, and 31st, but did not lie on the ground, 

 the temperature of which was high. 



April. — The weather of April was cold, dry, and, com- 

 paratively speaking, sunless. The mean temperature was 

 only 42°'6, the lowest since 1886, and the highest temper- 

 ature recorded 57°'3, the lowest absolute maximum since 

 1879. At no time during the month was anything like 

 spring weather experienced, for although no frost was 

 registered after the 8th, the cold, humid winds off the North 

 Sea made conditions exceedingly trying. There was a fog on 

 the 8th, and snow fell on the 14th. 



May. — The characteristic features of the weather of May 

 were a low mean temperature, small rainfall, and excess of 

 sunshine. There was again a deficit of warmth, the absolute 

 maximum of 67°*9 being one of the lowest May maximums
