Mr D. Milne on Earthquake Shocks felt in Great Britain. 125 
occurred) the same,—the mercury very low, and weather calm 
and rainy. After the 23d, however, the mercury got unusual- 
ly high. On the 23d, the cows were observed to be all on 
their feet (quite unusual after 10 p.m.) ; very restless, and show- 
ing every symptom of fear. The dogs in a farm-house ran to 
the door, and howled mournfully. The only other cireum- 
stance which occurs to me connected with these earthquakes, 
is the sulphureous smell which was perceived. This was sup- 
posed to come off the river; but several persons at a consi- 
derable distance from the river were sensible of it. Although 
I heard of many who said they perceived this, I would not be- 
lieve it, till one evening Mrs C. was standing at the water- 
edge, and wishing to convince me of its reality, asked me to 
go to the water-edge. I did so; and I must say that the 
smell was so strong, that it could not be mistaken. It was a 
little after sun-set, and the evening having suddenly turned 
to intense frost, the whole course of the river could be traced 
from a distance, by a sort of vapour or mist that arose from 
it,—most favourable for giving out any effluvia. Having men- 
tioned the circumstance to a friend, and gone with him to the 
same spot about two hours afterwards, neither of us could then 
detect the smell.” 
(3.) J. Drummond, shoemaker, in some written observa- 
tions, with the perusal of which the author was favoured, says 
—‘* Where the shock is perpendicular, we feel in general two 
violent concussions—sometimes there is only one. In the 
great shock of 23d October, there were three concussions. 
At each concussion there is a quivering of the earth, with a 
rumbling noise—the undulating shocks causing the earth to 
rise like two waves.” 
On the foregoing passage, Mr Macfarlane makes the fol- 
lowing remarks. ‘ This double shock or ‘ dunt’ (the first most 
violent), is certainly a remarkable accompaniment of many 
of these earthquakes, and that not of the apparently perpen- 
dicular ones only. Subsequently to the first comparatively 
violent part of the shock, there is a trembling of the earth 
and hollow rumbling noise proceeding from the point where 
it is supposed to commence swelling (if the shock is not given
