These results are sufficiently consistent to assure us that we cannot go far 
78:344 
wrong if we multiply the new results by the factor 
= 1:13 in order to render 
them comparable to those of the old as far as treatment is concerned. 
If we perform this operation we shall find that the mean yearly value for the 
Kew series becomes 51:607, while the mean yearly value of the old series was only 
30:468. 
If we may suppose that this difference represents the effect of change of locality, 
and that the second series is large enough to divest a comparison between the two 
from the influence of seasonal peculiarities, then we may conclude that the Kew

to reduce it to London value. In the following table we have given the London 
and the Kew yearly values, in the first column of which the Kew values are 
merely corrected for difference of treatment, while in the second it has been 
attempted to correct them for change of locality.
