I have alfo explained, in that Treatife, how a ftiil more 
lingular effect might he produced, namely, how * “ an explo- 
“ fion, which happens in one place, may caufe in a fecond 
“ place (at a verv confiderable diftance from the firft place) 
“ a fudden returning ftroke, which may knock down, or even 
“ kill, perfons and animals at that fecond place; at the fame

“ where the lightning falls, and the fecond place (juft men-

“ fhall receive no detriment whatever.” 
§ io. Having, in my Principles of Electricity -f, explained at 
large the nature of the returning ftroke , I will not trefpafs upon 
the time of this Society, by repeating the account of any of 
the various experiments that I made, to prove the poftible 
exiftence of fuch an electrical ftroke ; but I will, at once,, 
apply the general laws, which I have (therein) laid down, to 
the particular phenomena related bv Mr. Brydone. 
But, before I fpeak.of the accident of Laudek, which ap- 
pears to me to have been occafioned by a returning Jirok-% pro-

“ when he obferved a lamb (only a few yards from him) drop 
“ down, although the lightning and claps of thunder were,
