to the observations made by Mr. Walker from 1786 to 1793, 
we find that in 1789 he collected 50'998in., and in 1792 
55-250in. Since this period the rainfalls exceeding 40in. 
have been 1822, 44'767in.; 1823, 42-941in.; 1828, 45-267in.; 
1830, 40‘861in. ; 1833, 41'677in.; 1836, 45-351in.; 1841, 
41T90in.; 1845, 4D415in.; 1847, 43’555in.; 1818, 45’230in.; 
1852, 45*730in. 
At the time Mr. Walker registered his excessive falls, the 
mean annual temperature was lower than it has been since, 
and reference to my paper, “Inquiry into the question 
Whether Excess or Deficiency of Temperature during part 
of the year is usually compensated during the remainder of 
the same year” (Memoirs, vol. 2, third series, p. 424), will 
show that between 1781 and 1791 a lower mean tempera- 
ture prevailed than any we have had since. The other 
years in which excessive rainfall occurred, 1822, 1823, 1828, 
1830, 1833, 1836, 1841, 1845, 1847, 1848, and 1852, appear 
to have been irregular as regards temperature; the years 
1822, 1828, 1833, 1841, 1847, 1848, and 1852, had a tem- 
perature above the average, whilst 1823, 1830, 1836, and 
1845, had a temperature below the average. Taking the 
average rainfall of each of these series it appears that the 
heaviest rainfall occurred during the warmer years. 
Returning again to the year 1872, the rainfall rises above 
the average in every quarter, especially in the third, the 
excess in that quarter reaching 7‘104in.; in the last quarter 
the excess was very small. 
Every month excepting May, August, November, and 
December, had a rainfall above the average, the falls of 
June, July, and September being most remarkable, each of 
these months having a fall of more than double the average. 
The very heavy fall in the middle of July was accom- 
panied by a great flood in the Medlock here, and there is 
every certainty that such a rainfall again must be accom- 
panied by a similar flood and great destruction of property.
