The years distinguished by the smallest animal fall of rain, both 
at Chiswick and Greenwich, are 1847, and 1864. The least annnal 
rainfall at Chiswick was 15’8 inches, the year 1858. The greatest 
annnal rainfall at Chiswick was 32‘6 inches, the year 1852. By com¬ 
paring the falls of rain at Chiswick and Greenwich together, year by 
year, we see that generally the fall at Greenwich is the greater in 
amount, and this excess at times has continued for several years toge¬ 
ther. These instances are :— 
From 
1826 to 1828, the excess in 3 years was 
1837 to 1839, ,, 3 years was 
1847 to 1853, ,, 7 years was 
1857 to 1861, ,, 5 years was 
1865 to 1869, ,, 5 years was

There is reason to fear that the rainfall at Chiswick in the last three 
or four years has been somewhat too small in amount. 
At times, however, it has been greater at Chiswick than at Green¬ 
wich. -These instances are:— 
The year 1829. 
,, years 1832, 1833, and 1834. 
„ years 1836, 1840, 1843, 1845, 1846, 1854, 1855, 1856, 1863, and 1864. 
One year the amounts were the same, viz., in 1862. There are twenty- 
nine instances of Greenwich being in excess ; and fourteen of Chiswick 
being in excess. 
The mean at Chiswick is 23*5 inches, 
Greenwich is 24*5 inches,
