At Kenmore, as the Rey. Mr Duff relates, “at 3 p.m. asea- 
man happened to be employed in a boat-house close upon the 
river, when the building shook to such an alarming degree that 
he rushed out in the dread that it would be instantly in ruins ; 
and on reaching his house, which is also but a few yards from 
the river, he was told by his wife that the bell in one of the 
rooms had been ringing.’ In a subsequent letter, Mr Duff 
says, that “the first circumstance which attracted the seaman’s 
attention was a tremulous motion of the loose objects in the 
building ; and, as he expresses it, a clattering of the slates 
over his head. The house merely trembled, and he was 
not sensible of a general movement in any direction. The 
thing bearing the greatest similitude to what he felt, is the 
tremor in a steam-boat, occasioned by the stroke of the arms 
of the wheels in the water.” 
The Rey. Mr Dewar was that day riding on a turnpike road 
on north side of Loch Tay. He heard a noise, apparently to- 
wards NE., similar to that of two or three carriages. His 
pony was startled by it. The day was very wet and rainy.

At Dunira several shocks were felt by Mr George Clerk 
Craigie, who thus writes regarding them :—“ At about 2} a.m. 
every inhabitant of the house was awakened by a shock so se- 
vere as to shake the whole house, and accompanied by a noise 
as loud as, and much resembling, a severe thunder clap. The 
motion was at first of a lifting description, as if some one was 
forcing up the bed, and finished with a tremulous motion. The 
time occupied was from 15” to 20’. The sound seemed to be 
both in the earth and air. The atmosphere was cloudy and 
calm, what we are accustomed to call muggy. Much alarm 
was felt by the domestics of Lady Dundas’s household, and 
likewise by some of the peasantry. Another shock took place 
at 6 a.m., but comparatively slighter.”’ 
At Ardvoirlich, the first of these shocks is stated by those 
who there heard it, “‘ as particularly severe, and the noise was 
described as having a sort of hissing sound, and was compared 
to a large steam-vessel letting off the steam.”
