It is not demonstrated that the numbers of the last column 
represent exactly the lowering of the water in a century ; for it 
has not yet been sufficiently determined if this lowering be uni- 
form, or if it vary at different periods, and if it depend upon 
some local circumstance, upon the climate, or upon the state of 
the atmosphere. Nor is it properly established that this lower- 
ing, which becomes less perceptible from the north of the Baltic, 
until it disappears entirely at the southern extremity, follows 
precisely the same law of diminution as the latitude. It appears 
to be uniform in the whole extent of the Gulf of Bothnia, and it 
rises about four feet and a quarter in that region. At Calmar, 
(Lat. 57° 50') it is only two feet, but it is not yet known whether 
it decreases in a regular manner between these two places. 
Some authors consider the facts related by MM. Bruncrona 
and Hallstrom, as deciding the question in favour of those who 
believe in a lowering of the level of the Baltic. The editor of 
the Annalen der Physik goes farther, and seems to consider 
it as confirming the opinion of a general lowering of the level of 
the sea. In support of this opinion, he adduces the traditions
