Also in 1866, though the September fall in that year exceeded the 
January fall, the latter still amounted to nearly 5} inches; and 
again in 1868, though the December fall exceeded that of 
January, the latter still had very nearly 5 inches. 
The driest period of the year at Bath appears on an average to 
be from March to June, both months inclusive. In no one of these 
four months does the mean rain-fall amount to 2 inches,—the least 
fall occurring in June. 
The greatest rain-fallin any single month during the decade 
was 6.734 inches. This was in September, 1866, when rain more 
or less fell every day in the month except one. 
The least rain-fall in any single month was 0.036 inches in 
September, 1865; there being no single month in the decade 
absolutely without rain. It may be noticed, though probably a 
mere accident, that the greatest and least falls both occurred in 
September. 
There are one or two features in the rain-fall of June and July 
deserving mention. The average fall for these two months com- 
bined is 3.712 inches. Whenever the combined fall is in excess 
of the average, the greater part of the fall is found in the Table to 
occur in one of those two months, and generally in July, instead 
of both months being equally wet. When the combined rain-fall 
is below the average, it appears to be pretty equally divided 
between the two months. There is an exception to this last rule 
in the year 1873, when the fall in July was more than an inch 
and a half in excess of the June fall, but then the whole fall was 
only a very little below the mean. 
Passing on to the average autumnal rain-fall at Bath, it is 
observable that the greater part of the rain at this season falls in 
‘the two first months, September having the highest average, 
October the next highest, and November the lowest average. 
There is not much difference between the averages of September 
and October, but it is worth noting that in most of the years there 
was a great excess of rain in one of these two months above what
