COMPARATIVE RAINFALL, DORSET AND THE R.O., GREENWICH, 

 185695. 



EXPLANATION OF TABLES IN THE APPENDIX. 



TABLE I. Number of Dorset Rainfall Stations, with the average 

 rainfall in every year from 1856 to 1895. The depth of rain in 

 different years is not comparable, owing to the constant changes of 

 stations. 



TABLE II. Proportionate rate of fall, corrected for inequality in 

 the length of the months by dividing the Rainfall, Table I., by the 

 number of days January by 31, February by 28 and in leap year 

 29, and so on, and then ascertaining the ratio to the annual fall. 



TABLE III. Total rainfall when a register has been uninterrupted 

 through any Decade. The Decades are independent, but the rain 

 at any Station in one Decade is comparable with the rain at the 

 same Station in the others. 



TABLE IV. Ratio of the monthly to the annual Rainfall, deduced 

 from Table III.
