the mean is at a minimum. It is worthy of remark that while the 
ascent of the mean temperature from the minimum to the maximum 
takes seven months, the descent from the maximum to the mini- 
mum takes only five. In other words the passage from winter 
to summer is much slower and longer about than the passage 
from summer to winter ; though in this last ease, from the fall of 
temperature being not very rapid during the first three months of 
its decline, there is seldom much frost or cold in Bath previous to 
November.

It will be seen here that the absolute maximum temperature 
during the above nine years has occurred four times in July, three 
times in August, and twice in June. 
The absolute maximum has attained to 90° or upwards in only 
two years, 1868 and 1870,—in both instances, in the month of 
July,—the highest bemg 90°.5 in 1868. 
There is no year in which it has not attained to 83° or 
5 upwards, the mean absolute highest for the whole period being 87°. 
Tn no year has the absolute maximum attained to 70° before 
the month of April, in which month a temperature of 70° or 
upwards has occurred in five different years. Nor has the same
