these years is 67'22, while the sum oi the mean ranges for these months 

 for the whole series is 64*92. On the other hand, the sum of the mean 

 ranges for the six summer months of the maximum years is 104*87, 

 while the similar sum for the whole series is 103*13. Thus the increase 

 for the winter months of the maximum years is not only relatively but 

 even absolutely greater than that for the summer months. 



18. It may be remarked, in conclusion, that the method of dealing with 

 meteorological observations herein indicated may be applied in various 

 ways to the elements of the same station and also to those of different 

 stations. 



The author forbears to mention these various ways, which will occur 

 to every meteorologist. He cannot, however, help thinking that an 

 extension of the present method of investigation is likely to lead to 

 interesting results.
