QUANTITY OF RAIN. cix 
234. Annual Variation of the Fall of Rain.—From the means for 18 years at the foot of Table 101, the 
greatest amount of rain fell in October, and the least fell in April, the daily average for the latter month being 
rather less than half that for the former. The amounts of rain for the months of June, July, August, Septem- 
ber, and October, differ little, the average daily fall for these 5 months being 0:0894 inch. The daily means for 
the quarterly groups with the greatest range of values are as follow :— 
in. in. 
Winter, Nov., Dec., Jan., =0:06738 Summer, June, July, Aug., = 0-0788 
Spring, March, April, May, =0:0519 Autumn, Sept., Oct., Nov., = 0-0902 
in. 
Year, = 0:0722 
235. Amount of Rain with reference to the Moon’s Age.—This discussion was given in the volume for 
1844, p. 447. The result, as obtained from 6 years’ observations of the Observatory gauge, may be stated 
shortly thus :— 
The average daily fall of rain during the second and third quarters =0-0654 inch.

So that a greater amount of rain fell about new than about full moon. (See Foot-note to No. 227.)
