306 Mr D. Milne on Earthquake Shocks felt in Great Britain, 
again to the eastward. My own feeling was, that an immense 
body struck the floor under my feet, as well as the other parts 
of the house, with great violence.”’ 
Monzie, about ten miles north-east of Comrie-—Mr Laurie 
writes :—‘ On the 23d, at 13 minutes past 10 in the evening, 
we heard the well-known sound again approaching. When it 
had continued a few seconds, we felt one or more abrupt con- 
cussions, similar to that of the 14th, but more severe ; this was 
followed by a violent tremor which lasted a good many seconds. 
The concussion already described formed, in both cases, the 
commencement of the earthquake, if we except the mere 
sound ; after the concussion, followed a general shuddering of 
the ground where we stood or sat. The shocks of the 14th 
and 23d were preceded, accompanied, and followed by a sub- 
terranean noise. The quantity of rain that fell in October 
this year, was very great. The shock of the earthquake af- 
fected the nerves disagreeably, and left a painful impression. 
It reminds me vividly of the shock from an electric machine ; 
you wish to experience it, but having once done so, you never 
wish it repeated.” 
Blairmore,aboutten miles north-eastof Comrie.—Mr Buchan, 
an intelligent farmer there, relates: —“I wasin bed at the time. 
Of the sound that preceded, J had no consciousness. I felt 
confused, and had a strong presentiment of some approaching 
danger. In this state, which was but for a few seconds, I felt 
as if some one had taken hold of my body and given it a vio- 
lent shake, which added greatly to the confused and unplea- 
sant sensations I had before. This motion or shake, again, 
was followed at the distance of about two seconds of time by 
a sudden and fearful heave upwards, with great unsteadiness 
or quayvering motion, and immediately an equally sudden mo- 
tion downwards, when all appeared to rest as before. The 
force by which the upward movement of the earth was occa- 
sioned, which appeared tremendously great, did not appear to 
me to act exactly perpendicularly, but rather in a slanting 
direction, as if something had been forcing a passage a little 
below the surface of the ground, from west to east, and going 
with great rapidity, for the bed on which I lay stands east 
and west, and the west end was raised first, and seemed to be
