With respect to the mean depression of the dew-point, it 
appears from the above Tables that at Bath it is the same in 
spring and summer, showing however a perceptible difference in 
both these seasons from what it is in the other towns, the main 
feature in this difference being—that whilst in spring the mean 
depression at Bath eacceds that of all the other towns except 
Camden Town, in summer it is Jess than any of the others. This 
seems to indicate a drier atmosphere at Bath in spring, and a 
more humid one in summer, though when we look to the mean 
relative humidity, the former difference disappears in the spring 
season as regards Oxford and Greenwich, though manifest enough 
in respect of Royston and Norwich. Camden Town situate in the 
north of London has a greater depression than Bath in spring by 
0°.8, and a less relative humidity, shewing it to be the driest of 
the series at this season, while Royston has the least mean depres- 
sion, and the highest relative humidity, in the same season showing 
it to be the dampest. Norwich occupies an intermediate place. 
In summer the greater humidity of the air in Bath than that of 
all the other towns above specified, is clearly shown, whether we 
look to the mean depression of the dew-point, or to the mean 
relative humidity deduced from it. 
In autumn we find this humidity increased ;—much in excess 
of what it is in Bath itself in summer, in the same excess also as 
before compared with the other towns, especially Camden Town, 
Royston and Norwich. 
In winter there is a still further increase of humidity in the air 
at Bath, but at this season it is not very different from that of the 
other towns, with the exception of Greenwich and Norwich, the 
former of which is less humid than Bath, the latter more so. 
The general result of the above, then, seems to be—that Bath 
is decidedly more humid in summer and autumn than towns lying 
further to the east, but that in winter and spring, with regard to 
most of the towns specified in the Table, there is no very material 
difference.
