110 Mr D. Milne on Earthquake Shocks in Great Britain. 
7th October 1839. 
There were five shocks felt on this day by different observers, 
of which three only are marked in the register. The other two 
are said to have occurred at 4} a.m., and 113 a.m. Mr Max- 
ton at Cultoguebey (1 mile east of Crieff), between 11 and 12 
a.m., heard a noise loud and rumbling, but no shake ; about 3 
p.m. he felt a decided shake of the ground, accompanied by a 
noise in air like thunder. The shake resembled what may be 
felt on a moving bog or moss. The concussion came from W. 
He was then on low flat sandy ground. About 4 p.m. he 
heard a slight noise, but felt no shake.

Mr Buchan of Blairmore writes,—“ Not long after 2 a.m. 
when in bed, I heard a sound, which, as formerly, somewhat 
preceded the shaking, appeared much nearer, and with ap- 
parently less time intervening ; also louder and harsher, some- 
what resembling one of these winds called by countrymen 
‘hearkening winds.’ They come in heavy gusts with a roar- 
ing sound, die away after a little, and again roll as before. 
The motion (which almost immediately followed the sound), 
was very unpleasant. It appeared as if my bed had been sus- 
pended to the top of the room, and had then received a smart 
and violent blow from a heavy mallet. I was not conscious, 
however, of any swing, but merely a tremulous or quavering 
feeling, occasioned by the motion of the bed. You may pos- 
sibly better understand what I mean by the pendulum of a 
clock when oscillating ;—if it is smartly struck by a small in- 
strument, it has a very reverberatory and unsteady motion for 
a short time.”

At Comrie the shock (says the Rey. Mr Walker), “ caused 
considerable upheaving of the earth. It was accompanied 
with a very loud noise resembling hollow thunder, increasing 
in intensity as it approached us, and again decreasing as it re- 
ceded.” 
At Dunira, 3 miles west of Comrie, the shock is described 
by Sir D. Dundas as “severe, and weather muggy and close.’ 
At Strathallan, about 10 miles SE. of Comrie, there was
