Mr D. Milne on Earthquake-Shocks felt in Great Britain. 115 
tolerably severe shock under us. The pigeons also at the 
same time kept flying about, as if in a state of alarm. We 
all at the moment attributed this to the earthquake. The 
day was close and oppressive. The rain came on at two 
o’clock, and continued very heavy all the rest of the day.” 
At Monzie Mr Laurie, the parochial schoolmaster, writes. 
“I heard two long loud peals, and there was a tremulous 
motion observed by some persons. A pond in Monzie Park 
was seen to be agitated as if by the wind, though it was a per- 
fect calm at the time.” 
A correspondent at Blairgowrie thus describes the shock in 
that district, which is probably about forty miles E.NE. of 
Comrie. The first one felt there in October was about 3 p.x. 
It was felt “only in the valley of Glenshee, about ten or 
twelve miles to the north of this town. The concussion was 
preceded by a hollow rumbling noise, which induced those 
near a road to fancy that there were several carriages passing 
along at a rapid rate, and those at a distance from any road, 
to imagine in some cases that it was occasioned by thunder, 
and in others by some of the outhouses falling to the ground. 
After the noise had continued about 5’ or 6’, a tremulous mo- 
tion or tremor was felt, but without any movement from side 
to side, or in an upward direction. One man who happened 
at the time to be fishing on a hill burn, about fifteen miles 
to the N. of this, in Glenshee, gives a very distinct account of 
the phenomena observed by him. He states, that he was at 
the moment walking across a patch of heather, when he heard 
a noise as if of a large covey of muir-fowl flying at a little dis- 
tance from him, and he indeed imagined the sound to proceed 
from this cause. Finding that it continued, and seemed ap- 
proaching him, the thought immediately struck him that it 
must be the approach of an earthquake, such as those he had 
been frequently reading of in the newspapers of late as having 
occurred about Crieff and Comrie. He therefore stood quite 
still, leaning on his fishing-rod to observe the phenomenon, 
and heard the sound distinctly approaching, until it seemed 
to surround him, when he felt the ground tremble under him 
(to use his own words) ‘ as if shaken in a riddle’ He states 
the sound to have proceeded from a west or NW. direction, 
and as resembling the sound of * Muir-burn, or the rattling,
