THE YORK RAINFALL. 
Fortunately the lost records, left to our Library by the late 
John Ford, from 1831 to 1870, have been discovered, except 
for the year 1831 itself. The rainfall values for this year were 
however supplied by him to the late G. J. Symons, and are 
thusppreserved for us. 
The 1811-24 values are from the monthly means for those 
years, presumably by Mr. Jonathan Gray, used by Professor 
Phillips in his “ Rivers, Valleys, and Seacoasts of Yorkshire." 
These records were begun in 1801. The discovery of them 
would be of great interest and value. His gauge appears to 
have been placed 3 feet above the ground. The values given 
by Phillips have therefore been increased by 3*3, on grounds 
which have most recently been stated in the 1900 volume of 
“ British Rainfall,” by Mr. Hugh R. Mill. 
In the two decades, now added, the driest years were 
1834 (i 8'49 ins.) and 1896 (21*98 ins.) The wettest were 
1839 (26*43 ins.) and 1894 (28*08 ins.) The last decade, 
with an average fall of 24*326 ins. was 0*675 under the mean 
for the previous 50 years. But the “ wet days ” exceeded 
the same mean by no less than 16 h days, being nearly the 
same as the mean for the seventies and slightly less than the 
eighties. 
The values for each decade are shown in the accompanying 
tables :
