Mr. Pengelly has recorded the average number of wet days in 
each month at St. Mary Church during the same nine years. 
These averages are not more in excess of the Bath averages than 
might be expected from the increased quantity of rain at St. Mary 
Church, and the relationship between the several months in this 
particular is much about the same. The chief difference appears 
in the months of February and March, which seem to be wetter, 
relatively considered, at St. Mary Church than at Bath. The 
yearly average number of wet days at St. Mary Church exceeds 
the yearly average at Bath by twenty-two. 
The greatest fall in twenty-four hours during the nine years was 
2.13 inches. The average greatest fall in twenty-four hours is 
1.52 inches. This last does not much exceed the average greatest 
fall in twenty-four hours in Bath. 
Taking next into consideration the rain-fall at Exeter, Dr. 
Shapter, in his work before alluded to, sets the yearly average 
there, from the measurements of forty-four years, 1817-1868, at 
twenty-nine inches. This is nearly one inch less than the yearly 
average at Bath. But, as is the case in other places, he states that 
the amount varies much in different years, the maximum and 
minimum yearly falls during the above period being 42.5 inches 
and eighteen inches respectively. The difference between these 
two measurements, or the range of the yearly fall, amounting to 
24.5 inches, very much exceeds the range of the same fall at Bath, 
which is under seventeen inches, though the Bath extremes would 
probably approximate more closely to those at Exeter, were 
the Bath rain measurements continued for as long a term of 
years. 
Dr. Shapter states the autumn to be the wettest season at Exeter, 
and November the wettest month. This is not the case in Bath, 
where, though the autumn rains as a whole are, in amount, not 
very much less than the winter rains, the wettest month in 
particular is decidedly January. The driest month at Exeter he 
states to be July; at Bath it is June, as at present determined ;
