and other fruits, the thermometer falling 10° below freezing, and 

 it was also 7° below that point on the night of the '26ih. Snow 

 fell on the morning of the y5th. There was a very heavy 

 thunder-storm in London on the 8th between 1 and 2 p.m. ; 

 some hail fell in the Garden in the afternoon. 



May. — This month was still unfavourable to vegetation ; for 

 the winds were generally cold and diy, from north, north-east, and 

 east ; and in six nights the thermometer indicated below freezing. 

 On the 10th it was 5° below that point. The mean temperature 

 of the month was upwards of 2^° below the average, and there 

 was scarcely the usual quantity of rain. None fell between the 

 15th and 27th inclusive. The 9th and- 10th were boisterous, 

 with rain. There was lightning on the evening of the 27th, and 

 the 29th was cold and cloudy with thunder-showers. 



June. — Dry weather prevailed till the ^th, and between this 

 and the 14th there fell an abundant supply of rain. The weather 

 on the whole was favourable to vegetation. The mean temperature 

 was little more than a degree below the average, whilst the 

 amount of rain was upwards of half an inch above the usual 

 quantity, and nearly one-third of it fell on the 13th alone. 

 South-west winds set in on the 24th, and were strong from the 

 27th to the end of the month; the 28th and 29th were even 

 boisterous. Heavy thunder-showers occurred on the 1 4th between 

 2 and 3 p.m. 



July. — The mean temperature was nearly 1^° below the 

 average. The mean minimum was however j° higher than 

 usual; whilst the mean maximum was 2 "69° lower than its 

 average for July. These conditions may be thus respectively 

 accounted for : twenty-three days in this month of warm south 

 and south-west winds maintained a mild temperature at night, 

 but the great amount of vapour which they brought along with 

 them prevented the sun's rays from raising the temperature 

 of the days to its usual height. The quantity of rain was about 

 one and one-third of an inch above the average. On two days, 

 the 13th and 27th, nearly an inch of rain fell on each day, and 

 on the 14th more than half an inch in four hours. There was 

 much lightning, with thunder and rain, on the nights of the 8th 

 and 27th. The 30th was very boisterous. 



August. — The mean temperature was upwards of 2° below the 

 average ; and, as in the last month, the diminution was owing 

 more to lowness of day temperature than that of the night, the 

 former being 3° below its average, the latter but little more than
