During this period the leafing of the more forward trees has proceeded, for the 
most part, under the retarding influence of cold breezes: Twice, the temperature 
having risen for a few days, the accumulation appears to have gone off in local 
thunder-storms, In travelling on the 17th inst. from Bristol to Southampton, I 
had the rare opportunity of observing, from a convenient distance, the gradual 
formation and discharge of a prodigious Nimbus, forming part of a series of clouds 
which for several hours continued to pour a flood of rain, accompanied by large 
hail, thunder, and lightning, on the country about Audover and Winchester. As 
the san, which was declining, strongly illuminated these clouds, they reflected a 
lively copper tint above the indigo ground which marked the heavy rain: the 
electrical light which fills the striking cloud at each discharge was, therefore, 
with the stroke itself, imperceptible ; as was the thunder, from the distance: and 
the phenomena I had to supply (as to certain evidence) from subsequent inferma- 
tion as we passed over the tract thus plentifully irrigated. 4
