OBSERVATIONS ON RAINFALL. 
By Francis Dix. 
Read 26th February, i88g. 
Having taken the rainfall in South Norfolk for the last fifty years 
(at Dickleburgh about thirty-six years, and at Norwich fourteen 
years), I have prepared a table which shows the monthly average 
for each year during that time. 
The average rainfall during the last fifty years, 1839 to 1888 
inclusive, has been for the first six months 9.84 inches, for the 
last six months 14.58 inches =24.42 inches. 
During this period three instances have occurred in which no 
rain has been registered in the month; namely, April, 1855, 
February, 1857, and September, 1865 : the last was followed by a 
wet October, 6.67 inches rain. 
There were twenty-four years with a rainfall above the average — 
eight years of 30 inches and upwards, viz. — 
1841 = 30.65 ins. 1848 = 32.42 ins. 1860=30.00 ins. 1875 = 30.1 1 ins. 
1877 = 31.44 „ 1878 = 32.80 „ 1879 = 32.06 „ 1882 = 33.34 „ 
There were twenty-six years with a rainfall below the average — 
seven years below 19 inches, viz. — 
1840 = 18.86 ins. 1847= 18.40 ins. 1855 =18.25 ins. 1 858 registered-18.64 ins. 
1863 = 16.75 ins. 1864=14.21 ins. 1868=17.39 ins. 
The two highest registers were 32.80 inches in 1878, producing 
the Norwich Flood, and 33.34 inches in 1882. 
The two lowest registers were 16.75 inches in 1863, and 14.21 
inches in 1864. 
The monthly rainfall has been as low as 0.50 inch and under, 
thirty-one times in the fifty years.
