By F. Dix. 
Read 26tli February, 1901. 
On the 26th February, 1901, F. Uix exhibited a chart of the 
rainfall during the past one hundred years, 4 feet 7 inches wide by 
3 feet 3 inches deep, which was headed, “ The Monthly, Half-yearly, 
and Yearly Rainfall, during the Nineteenth Century in the East 
of England,” compiled by Francis Dix; including 1801 to 1831 by 
Luke Howard at Tottenham (see ‘Climate of London’), 1832 to 1838 
by Mr. Squire at Epping (see ‘Moore’s Almanack’), 1839 to October, 
1874 at Dickleburgh, and October 1874 to December 31st, 1900, 
at No. 1, Essex Street, Norwich, by Francis Dix. 
This chart was ruled in 100 divisions from left to right, each 
division was headed by the date of the year with the monthly 
rainfall, that of the first and last six months, and the rainfall of 
the year entered thereunder. 
The lower portion of the chart was ruled for two feet with lines 
one inch apart, showing by up and down black lines the variation 
of rainfall from year to year, which amounted between 1847 and 
1848 to 14.02 inches, and between 1864 and 1865 to 13.26 inches. 
The lowest rainfall was shown to be 14.21 inches in 1864, and the 
greatest yearly rainfall to be 33.34 inches in 1882, a difference of 
19.13 inches. 
The average of the first 50 years in South Norfolk that was 
registered by F. Dix between 1838 and 1888, thirty-five years and 
nine months at Dickleburgh, and fourteen years and three months 
at Norwich, was shown on the bottom line as follows : —
