142 Earl Stanhope's Remarks on Mr. Brydone’s 
It is alfo evident, that it was the eledtrical returning fire, 
that produced the “ marks of fufion” on that part of tlie iron 
of the wheels which was in contadt with the ground ; inaf- 
much as the whole electricity, that, at the inftant of the ex- 
plofion, returned into the cart, did enter at thofe places. 
§ 23. No perfon, the lead verfed in the principles of elec- 
tricity, can hefitate to aflent to the propofition, that the cleclri - 
cal returning Jlroke mud exid, under circumdances limilar to 
thofe explained above. But it may be objedted to me, that 
although all the aforefaid effedts of a returning droke might 
take place in a fmall degree, yet thole effedts could not have 
been fufficiently powerful to have killed Lauder, the 
horfes, and the lamb, or to have melted the iron of the cart- 
wheels ; efpe’cially, conlidering the fmall quantity of electrical 
fluid that is contained in the body of a man, of a lamb, or of a 
horfe ; or that is contained in any body of the fize of a com- 
mon cart ; that is to fay, confidering the fmall quantity of 
electrical fluid that could, by being didurbed, have produced 
the returning Jlroke. 
To this objedtion (plaufible as at fird fight it may appear) I 
conceive, I have given a complete an fiver in my Principles of 
Electricity, from fedtion 337 to lection 347, inclulively ; and 
alfo from fedtion 592 to fedtion 6o6, inclulively; but it may 
not be improper to add a few words to what I have already 
faid upon that part of the fubjedt. 
§ 24. No legitimate conclufion can be drawn from premifes 
that are not proved : therefore, no perfon can legitimately 
conclude, that the force of a returning droke mud always be 
weak, when produced by the didurbed eledtrical fluid of a 
man’s body, by reafon that a man’s body contains but a fmall 
quantity of eledlricity : for, it has never been proved, that a 
man’s
