462 ESSAYS anp OBSERVATIONS 
of any like event that ever happened in 
any preceeding age of the world. 
THAT a tremor, which is hardly to be 
felt at land, or which may altogether e- 
{cape notice there, may be very percepti- 
ble-on the waters, will eafily be believed; 
nor is it more incredible, that a {mall con- 
cuffion given to a great body of water 
will produce a very remarkable agitation 
in the narrow creeks and fhallows. And 
it is obfervable, that thefe commotions 
were moft violent in the deepeft lakes, 
particularly in Loch-nefs; the extraordi- 
nary depth of which hath been fometimes 
affigned as a reafon for its never freezing, 
the fevereft winters not being able to re- 
duce it to the coldnefs of ice.
