368 Dr. Gray's Account of the Earthquake 
“ in bed (as I have already related) felt themselves lifted up, 
44 and shaken. From this circumstance, one is led to imagine 
44 the cause of the earthquake to have been within the earth ; 
44 yet, all the circumstances considered, I incline to think some 
44 violent concussion in the air occasioned it. The blast

44 which, in the south direction, bound this vale." 
The other account from Nottinghamshire is given by Dr. 
Storer, in the followingletter, dated Nottingham, March 12, 
1796. 
44 On the 18th of November last, at eleven o'clock at night, a 
44 very smart shock of an earthquake was felt in this town and 
44 neighbourhood. It was preceded by a noise, which appeared 
44 to me like that of dancing in the room over that in which 
44 I sat, accompanied by a clattering of the furniture ; and 
44 beginning, as seemed to me, at the north-east, and passing 
^ to the south-west corner of the room. To others the reverse
