ACCOUNT of EARTHQUAKES, &e. 241 
from N. W. to S. E. and by others from N.E. to S. W.; that 
they have not been obferved to affe& the barometer 3 that they 
do not extend in any direction above three or four miles from 
Comrie ; and that towards the fouth they are bounded by the 
Earn, which is in the immediate vicinity of the village. The 
fame perfon, though bettowing the minuteft attention, is often 
uncertain whether they proceed from the earth or from the air, 
fometimes believing them to come from the one, and fometimes 
from the other ; neither do all agree with re{pect to the feat of 
any one of them. . 
AFTER the ftricteft enquiry, I find it impoffible to determine 
with accuracy the date of any of the concuflions which took 
place before the 2d of September laft. Some people in the 
neighbourhood of Killin affert pofitively, that they heard un- 
ufual rumbling noifes in the month of May; but the impref- 
fion which thefe noifes made was fo faint, that they would pro- 
bably have been foon forgotten altogether, had they not been 
fucceeded by concuffions of a lefs equivocal nature. Towards the 
end of Auguft, two or three fhocks are faid to have been felt at 
Dundurn, Dunira Lodge and Comrie; but I have not been able 
to learn the precife day, or hour on which any of them happen- 
ed. The truth is, the concuffions hitherto obferved were feeble, 
and the minds of the people feem not to have been roufed to 
particular attention till the 2d of September. About cleven 
o’clock that evening, a {mart fhock was felt at Comrie. I my- 
felf heard here , for the firft time, a rumbling noife, which | 
took for that of a large table, dragged along the floor above 
ftairs, and which I probably would never have thought of 
again, unlefs my attention had been turned to it by the alarm. 
which. it had excited in the neighbourhood. Many other feeble 
noifes or concuflions are faid to have been obferved: in Glen: 
Leadnach and about Comrie during the months of September 
and Oétober. At that time, however, I confefs I was difpofed 
to doubt the numerous reports of earthquakes with which the
