what I have often felt in a thunder storm, or in an apartment 
highly charged with electricity.’’ 
(5.) Mr Philips of the Glenturret Distillery, situated close tothe 
Bridge of Crieff, writes that there was a double shock, ‘‘the se- 
cond shock following the first at the distance of about 12’ or 15’, 
with a much increased shaking and noise. Our premises, you 
are aware, are situated low down in the bottom of the Strath. 
At first there was heard, by a young man in the counting-room, 
a noise low, heavy, and distant, like that of machinery, for the 
space of about 3’; then ashock, like a great weight falling against 
the foundations of the house, accompanied by a brisk continued 
shaking and a tremendous noise ; then about 12” or 15” after- 
wards, a shock much heavier than the former, the shaking 
and noise very much increased, even terrific. Dust, scales 
from the whitened walls and ceiling, and even pieces of plas- 
ter from a stone partition, fell in abundance. The young 
man ran out of the house into the open air amid the darkness, 
but the noise through the court or square was such as to actu- 
ally frightenhim. He thought, indeed, that the chimney-stalk 
(new built) and the houses were all falling, and he ran back in- 
stinctively to save himself. The shaking and noise then gradu- 
ally died away together. The whole, from first to last, may have 
lasted for one minute and a half. The shocks and the noise 
appeared as if proceeding from N.NW. to S.SE. The shake or 
motion resembled that of a wave, 7. e. it moved rising and 
falling, as well as to and fro. Those in quiet places heard the 
noise, before the shock, while those beside machinery or other 
noise did not hear it until the shock was felt; but then indeed 
the noise of the earthquake obliterated that of machinery and 
every thing else, and some of the workmen ran to ensconce 
themselves in places of safety, under the impression that the 
houses and utensils were coming down into a heap. These 
observations as to direction of the shocks and as to the motion 
and noise, correspond exactly with what the excise-officers and 
workmen throughout the rest of the premises felt, and with 
what I, with my mother and brother, felt in our dwelling- 
house in Crieff, distant say 500 yards and on higher ground, 
as well as with what we all felt repeatedly in regard to the
