It will be seen that it is only during the wettest and driest 

 months of the year that Greenwich corresponds with Redhill. 



From April 18th to 21st, 1885, the sky was, so far as my 

 observation extended, quite cloudless, and again from May

The barometer was over 30 in. for 180 days, over 29 in. for 

 183 days, and fell below 29 in, on two occasions only, 

 Jan. 11th and Oct. 10th. 



The thermometer had an extreme range of 66-5°, the lowest 

 bemg 20° on Dee. 11th, and the highest 86-50° on July 26th. 

 I have recorded, since my residence at Redhill, an extreme 

 range of over 90°. 



The thermometer reached 80° and upwards on 5 days ; 

 70° and upwards on 43 days ; and sank to 32° and under 

 on 79 days. The thermometer fell to freezing-point and
