and Ancram, and was there from 48 to 50 miles *. M, Le 
Roy fuppofes the fire-ball feen July 17, 1771, to have been 
samiles high when it began, and 27 at its explofion +; but 
does not give the facts on which his calculation is founded, 
Every philofopher muft be ftruck with the agreement of 
thefe meteors in their diftance from the earth, . itt beyond the 
limits of our crepufcular atmofphere. ‘ 
§ 6. That a report was heard fome time after the meteor of 
the 18th of Auguft had difappeared, is a fa& which refts 
upon the teftimoty of too many witnefles to be controverted, 
and is, befides, conformable to what has been obferved in moft 
other inftances. In general it was compared to the falling of 
fome heavy body ina room above ftairs, or to the difcharge of 
one or more large cannon at a diftance. That rattling noife, 
like a volley of fmall arms, which has been remarked after © 
other meteors, does not feem to have been heard on this occas 
fion. From a comparifon of the different accounts, it appears 
as if the report was loudeft in Lincolnfhire and the adjacent 
countries, and again in the eaftern parts of Kent; in the inter- 
mediate places it was fo indiftinét as generally not to have been 
noticed, and all obfervers of credit in Scotland deny that they 
heard any thing of the fort. If, therefore, this report be connected 
with the burfting of the meteor, I fhould be inclined to fuppofe, 
that found was produced two feparate times, namely at the firft 
explofion over Lincolnfhire, and again when it feemed to butft 
foon after entering the continent. Ingenious men have ayailed 
themfelves of this found, to calculate the diftance and height 
of meteors; and the exactnefs attained by this method, in the 
computation of the late fire-ball from the report heard at
