358 Dr. Gray's Account of the Earthquake 
“ of hills, or on high ground ; but I have not heard of its 
44 having done any damage in this country/' 
From Worcester the following account of it was sent by 
Dr. Johnstone of that city, in a letter dated November

A description of its effects, not only upon the earth, but also 
under its surface, is contained in the two following letters from

44 On Wednesday night, about a quarter past eleven o'clock,
