37° Dr. Gray's Account of the Earthquake 
“ equally heard the noise, and had their attention awakened 
“ by it ; yet some felt the shock in an alarming degree, while 
“ others, at the distance of a few yards, perceived nothing but 
“ the noise, and the rattling of the furniture ; a few felt some- 
44 thing like an electrical shock, and nothing else. 
44 Though there are many mill-ponds, canal reservoirs, and 
44 other considerable pieces of water, in this county, which 
44 would have been liable to untoward accidents from any ma- 
44 terial agitation or elevation of their surfaces, I do not find 
44 that any such thing was observed. 
44 As it is unusual for workmen to be in the coal mines at 
44 that hour of the night, I have heard of but one instance 
44 where that was the case. In one of the mines there were a 
44 man and a boy ; the former felt nothing ; the boy, who was 
44 nearer the shaft, perceived a rumbling, which he supposed 
44 to be at the top of the shaft, but felt no shock. 
~ 44 I have seen few people here who were in the streets, or 
44 without doors, at the moment the earthquake happened, 
44 and of these no one perceived any light in the heavens; but 
44 it is reported that a light was seen by the passengers in 
44 some of the coaches ; and a very intelligent gentleman of 
44 Derby told me that, being in the street, he perceived, at 
44 the instant of the concussion, a remarkable coruscation, 
44 proceeding from the south-west quarter of the heavens, 
44 (which he could not then see,) and producing a gleam simi- 
44 lar to a distant flash of lightning, but of longer continuance. 
44 Others, at Derby, saw the same thing through their win- 
44 dows.
