Southern Finland. Mr B. remarks, that the peculiar relations 
of the lakes, morasses, and ridges, will seem the more sur- 
prising when we examine the new geographical map of Schu-

possess in regard to this district of the direction and the ac-

Scotland, since that time. The shocks then became so fre-

previously given to the phenomena, at least in this country :— 
and hence, the nature of the motion and of the sound accom-

themselves, came to be narrowly watched, and pretty exactly 
ascertained. The author having interested himself in the 
subject, he had the good fortune to find at Comrie, where the 
shocks were always most felt, an individual well qualified in
