The following table is arranged in the manner of the two previous tables, and 

 refers to the amount of the rainfall in inches :—

Eight of the months show a higher death-rate with a greater rain-fall, whilst 

 the remaining four present a higher death-rate with a smaller rain-fall ; never- 

 theless the average quantity of rain of both the years so constituted is almost 

 identical. 



As it would be tedious to reproduce in the text the relative prevalence of all 

 the winds given in the tables, it may suffice to select one of them, and to infer 

 from the fluctuations in that the relative frequency of others. The wind which 

 blows on the greatest number of days in the year is that from the south-west ; it 

 Avill therefore be the one most suitable to our present purpose.

In this table there appears no indication of a law of the wind affecting the 

 death-rate ; the averages of both the factitious years are somewhat above the 

 average frequency of south-westerly winds over the six years. I find, on arranging 

 the due east winds in the same manner, that the average of the twelve months 

 with the highest death-rate is 3-46, whilst the average of the months with the 

 lowest death-rate is 288 ; and that both of these averages are somewhat below 

 the average frequency of due east winds over the six years, which is 3'5. 



It will be interesting, in the last place, to ascertain whether the relative force
