In this Table the general indication is, that the mortality is greatest in those 

 months which have the greatest number of rainj days. There are certain ex- 

 ceptions. March is the first month in which the general order is reversed, and 

 in which, therefore, there is the highest mortality with the fewest rainy days. 

 But if, instead of comparing only the months of the absolute highest and abso- 

 lute lowest number of rainy days, we compare the four months which are below 

 the mean of the six with the two that are above the mean, we find that the 

 general rule holds good, — those months with the highest number of rainy days 

 giving the average mortality 251*7, whilst those months with the fewest rainy 

 days give an average mortality of only 249 1. The same may be said of July, 

 where the average mortality of the three months with the greater number of 

 rainy days is 206-9, whilst the average death-rate of the months with the fewest 

 rainy days is only 202 2. The months of August, September, and November, 

 which, in the above Table, oppose the general indication, continue so to do even 

 when all the months are compared. Thus, the average mortality of the Augusts 

 with most rainy days is only 177*9j whilst the average of those with the fewest 

 rainy days is 200-7. Of September, in the same order, the proportion is 171 '3 

 (most) to ly5-9 (fewest). Of November, 229-7 (most) to 244-4 (fewest).
