THUNDERSTORMS occurred on 25th May about 8 a.m., and 
again on the same day about 10 P.M., continuing until 6 a.M. 
the next morning. Thunder was heard on the 27th of the 
same month, in the early morning. 
A particularly heavy thunderstorm occurred on the 28th 
June, commencing about 7 P.M., and lasting fur several hours. 
This was the heaviest thunderstorm I have seen at Redhill 
since my residence here, commencing in March 1866. The 
lightning was almost incessant from 7 P.M. to 10 P.M., and then 
continued with less frequency until nearly midnight. Heavy 
rain accompanied the electric storm, but the rain did not begin 
to fall heavily until two hours after the electric discharges 
commenced. It was on this occasion that 2°20 inches of rain 
were collected. 
Other thunderstorms occurred. One on the 18th August, 
and another on the morning of the 20th of September, neither 
being very violent, and the one in September being of short 
duration only. 
An Avrora was observed on the evening of the 24th April, 
but the display was feeble and of short continuance.
