120 Mr. F. Campbell-Bayard’s Report of the 
the average. At all three stations February had a large number 
of rainy days. The other months are somewhat alike at all 
three stations, though the number of rainy days is on the whole 
smaller at Reigate Hill than at Wallington and Greenwich, 
except in August, when Reigate Hill had a number slightly 
larger than the other two stations. 
The number of falls of one inch and upwards given in 
Appendix II. are only eight, and are relatively very small, the 
highest being 1:55 in. on July 25th at Greenwich. It will be 
noticed how small also is the area of the different falls.

Mr. Baldwin Latham has most kindly furnished me with a 
table (Table V.) giving the duration of rainfall at Duppas House, 
Croydon. If we study this very valuable table we shall note 
how small the rate of fall has been. The total number of hours 
during which rain fell is 598:28 hours, which gives the actual

actual annual rate of fall as ‘0377 in. per hour. The greatest
