British Rainfall 1897 page18
It will be noticed that in the following table we have
included the records for 1896, whereas in British
Rainfall, 1895, the Seathwaite ratios could only be
given down to 1895; we have of course determined the ratio
for 1896, viz., 91.
It will give some idea of the work needed for the
preparation of such a paper as this, if we mention that
records from 147 stations have been utilized, and that the
aggregate number of yearly records dealt with has been 1,612
 an average of eleven years for each station,  the
Seathwaite record of 52 years being the longest, but
followed by a 49 year record at Keswick, by two of 42 years
(Coniston and Mirehouse, Basenthwaite), and by one of 41
years at Whinfell Hall.
We do not put forward the work as perfect, either as regards
the observations or the calculations, but nearly all the
observations appear correct, and we see no prospect of
better ones being available for years to come; and as
regards the extraction of the data and the calculations,
much of both has been done in duplicate, and only one error
(amounting to less than a tenthofaninch at one station)
has been detected, so that we trust that there is no fear of
anything serious having escaped detection, or of the general
conclusions hereinafter stated being materially modifed by
another halfcentury's work.
In the following tables the stations are given separately
for each county, viz., Lancashire, Cumberland and
Westmoreland, and in each county they follow very nearly in
the usual order from south to north.
Having explained how the mean values given (for each
station) in the last column have been arrived at, we have to
add a few words of comment.
As will be explained further on, the mean rainfall given in
the last column is also given upon the accompanying map, but
in some instances the stations are so close one to another
that the figures could not all be printed, and in all such
cases it will be noted that the stations are bracketed
together, and the mean of the group is stated; this is the
case with entries 2 to 5 inclusive, and it will perhaps be
wondered why the average is entered as 67 instead of 71,
which is the average of the four entries. The answer is,
that reference to the previous column will show that two of
the values are base each on only one year's observations,
whereas the others depend on nine and on ten years
respectively; and in working out the mean, the greater
import
