FROM ORDINARY DAYS OF THE ELEVEN YEARS 1890 TO 1900.

resulting order is also shown when the figures from D, H and V are added, and 
finally the order when the sunspot frequency is the criterion. It and It' are treated 
separately. 
When the size of It' is the criterion, the order is the same for all the magnetic 
elements, except that 1890 comes last in V, while 1900 comes last in D and H. 
There is less agreement between the results from the three elements in the case of 
It, but the differences between the pairs of years 1890 and 1900, 1892 and 1894, and 
last 1897 and 1898, are so small that little significance attaches to the precise order 
in which the members of the pair present themselves. In the final returns from the

three elements combined, the only difference between the R and Pd lists is that there 
is an interchange of place between 1892 and 1893, and between 1897 and 1898. 
Table XLII. deals with the twelve months in the same way that Table XLI. dealt 
with the eleven years. In Table XLII. the points of agreement between tjhe different 
elements in the same list, or between the same element in the two lists, are somewhat 
inconspicuous outside the mid-winter months. Successive months sometimes occupy 
very different positions, without there being a very large difference between their 
values of the ranges. A longer period of years would be required to eliminate 
satisfactorily what is accidental. Whether one takes R or E/, it is clear that 
December, January, and November fill the last three places. 
When the three elements are combined, May, July, and August are bracketed 
second in the case of P. In the case of P.' there is a bracket between April and July, 
and again between June and September.
