126 Mr D. Milne on Earthquake Shocks felt in Great Britain.

away in the distance. I never noticed two waves.” 
J. Drummond continues,—* When the great shock of 23d 
October occurred, I was between the outer and inner doors 
of my house. I felt the shock strike the ground perpendi- 
cularly under my feet ¢hree times, like the stroke of a ponder- 
ous hammer, and, as far as I can guess, lifted the ground six 
or eight inches. Having some sticks in my hand, the first 
concussion tossed them out of it, and I felt something squeeze 
my heart that forced an involuntary cry. I was powerless 
between the first and second concussions, but when I got the 
third I recovered. I made to the door instantly, expecting 
the house immediately about my ears. I thought each con- 
cussion would have tossed the house from its foundation. The 
quivering of the ground was fearfully sublime, as well as the 
concussions. ‘The noise in the earth and the rattling to and 
fro of the house and furniture, was truly awful. I felt the 
shock before I heard the sound, and the first concussion was 
the greatest,—the last weakest. There was not one moment 
between each concussion. Between the first, and the end of 
the sound of the last, there was about one minute. There 
were about twenty houses more or less damaged, chiefly to the 
east and west of Comrie. Though it rained for fifty-two 
hours before the shock, the barometer stood at fair. The 
rivers were greatly swollen, but instantly after they began to 
fall, though the rain continued the most of the night. 
Comrie Manse, situated about a mile to the south of Comrie 
village. The Rev. Mr Mackenzie, the parochial clergyman, 
states, that his manse faces the sun at 10 a.m., so that its gables 
run in a north-west and south-east direction. On the evening 
of the 23d, ** An inmate of the manse was very sensible of one 
undulation, z.e. as if the north-west corner of the house was 
first lifted up. It seems to be the prevailing opinion, that the 
shock heaved up the ground. The rent in Mrs M‘Ewan’s back 
wall seems to me clearly the effect of an undulating heave. 
This house is situated in Comrie village on the south side of 
the Earne, and runs from west to east. The rent is perpen- 
dicular, and is near the west end of the wall. The inner 
lobby partition has separated from the south wall at both sides
