13S Earl Stanhope’s Remarks on Mr . Brydone’s 
Let the two clouds be fuppofed to be charged (for inftance) 
with the fame kind of electricity, and to be both politive. 
Let us further fuppofe, that the lower cloud DEF be near 
the earth, only a little beyond the ftriking diftance ; and let a 
man, cart and horfes, be fituated at L, under that part (E) of 
the cloud which is theneareft to the earth. 
Now, let us fuppofe this cart to be afeending an hill, and 
to be in the fituation defcribed by Mr. Brydone, namely, 
to have “ almoft gained the higheft part of the afeent,” and to 
be followed by “ another cart” (M) lower down the hill. 
Let us fuppofe alfo, that the two clouds DEF and ABC be 
near each other, perpendicularly over the place where the cart 
L was fituate (as at DA). 
And let the remote end C, of the upper cloud ABC, ap- 
proach the earth, within the ftriking diftance, and fuddenly 
dilcharge its electricity into the earth at G. 
§ 15. Things being htuated as above defcribed, let us exa- 
mine what confequences muft follow. 
Firft, when the upper cloud ABC difeharges its electricity 
into the earth at G, the lower cloud DEF muft immediately 
difeharge its eleCtricity into the upper cloud at the place DA, 
which is directly or nearly over the cart L. 
This accounts for the “ loud report” of thunder that was 
unaccompanied by lightning at L or at M. The report 
muft be loud, from its being near ; but no lightning could 
be perceived at L or M, by reafon of the thick thunder cloud 
DEF being fituated immediately between the fpeCtator at M 
and DA, the place between the two clouds where the lightning 
was. 
§ 16. Secondly, as the lower cloud DEF did gradually ap- 
proach towards the earth at L, fo as to come finally into the 
htuatioa
