British Rainfall 1895 page 21
appear to be independent of the mean rainfall, it seems to
prove that the period 1855 to 1857 in the Lake District was
exceptionally dry - and this is confirmed by the table on
p.19 of British Rainfall, 1867, where the ratios for
the three years at Troutbeck are respectively for 1 year 60,
for 2 years 65, for three years 66, or 4, 6, and 9 per cent.
below even the Seathwaite values.
As regards the one wettest year, the average of the 45
stations give a ratio of 145 against the above 133 for
Seathwaite. As already mentioned, there were few wet
stations among the 45, but on the whole we expressed the
opinion that "At wet stations the extremes both of wetness
and of dryness are less pronounced than at dry ones." The
present investigation of the Seathwaite records confirms
this as regards wetness, but negative it as regards dryness.

Seathwaite we were surprised to find that a previous
observer had taken away the old MS. observation books; we at
once wrote to asked for them, and were told in reply that,
as they were supposed to be of no use, they had all been
burned! Forunately we have the whole of the monthly totals
for all the gauges, but we have not the daily fall for the
early years. However, it is useless to lament, and much more
sensibe to put on record what we have, hence the following
table, which is perfect for 24 years and for a few earlier
ones:-
