What would have occurred if the rainfall in J uly had been 
like that of 1828, llASOin., or 8 , 822in. in excess of what 
fell in July, 1872 ? 
Rain fell on 40 days in excess of the average of the last 
10 years (Proceedings, vol. 11, p. 184); rain fell upon the 
greatest number of days in January, June, September, and 
October, and upon the least in April. 
Whatever was the disturbing cause which produced the 
excessive rainfall, examination of the excess of each quar- 
terly period shows that it went on increasing until Septem- 
ber, and then apparently declined to the end of the year, the 
excess in question being — March quarter, 2*808in.; June 
quarter, 4*794in. ; September quarter, 7'104in. ; and drop- 
ping down in the December quarter to O l77in. only. 
As regards the temperature of the year, it was above the 
average in every quarter, Greenwich giving 
March quarter + 5'0° 
June quarter + 05° 
September quarter ... + 1 ’5° 
December quarter ... +1*7° 
^ in excesss of 
L the average 
1 of 101 years; 
so that in the case of last year a high temperature has 
accompanied the excessive rainfall.
