DORSET MONTHLY RAINFALL, 1856-95. 157 



TABLE V. Detailed monthly Rainfall in inches at every Station 

 included in Table III. 



TABLE VI. Summary of Rainfall at Stations of 20 years' stand- 

 ing and upwards. 



In several instances, where the rain was allowed to accumulate 

 for two months in the absence of the Observer, the proportionate 

 fall has been estimated by differentiation from the nearest station 

 or stations, and is shown within brackets. 



Decimal points have been omitted from the tables of ratios, 

 except of the annual Rainfall in the last column of Table II. 

 The number of ciphers to the right ot the unit in the explanatory 

 headlines shows how far the notation has been carried. 



To find the proportionate rate of rainfall of any month to the 

 40 years' average multiply its ratio by that of the year. 



For example January, 1872 ... -146 x 1'43 = -209 

 June, 1870 ... -023 x -70 = '016 



The Author has endeavoured to arrange the Tables in such form 

 that the records of years to come may be easily incorporated with 

 those of the past.
