will atone for his Boldnefs, I (hall think myfdf 
greatly favoured. 
I have a Son about 1 6 Years old, that has been 
for 6 or 7 Years pad troubled with fudden Fits that 
intirely take away his Senfes. I got him all the 
Helps I could, but to no purpofe ; at lad I fent him 
to St. Bartholomew’s Hofpital, as an Out-Patient 5 
and there he was turn’d out as incurable. So find- 
ing his Cafe defperate, I conftdered the Power of 
Eledricity, and made a large Machine for Eledrifying; 
and afterwards fhocking him commonly twice a Day, 
he has received fome Benefit: And lad Sunday , being 
May 15, he being on the Pededal, and very high elec- 
trified, and having on a coarfe Fudian working Frock, 
the condenfing Phial being on the Condudor, and 
I, touching him to procure Snaps as ufual, touched 
his right Shoulder Blade; and, to my great Surprize, 
the furzy-Flax of the Frock caught Fire, with a great 
Blaze, and burnt the whole Breadth and Length of 
the Shoulder, the Flame rifing 6 Inches above the 
Collar, and I believe would have fet the Frock on 
Eire, had I not put it out with my Hands. There 
was no Fire in the Room that Day : This was 
about Noon ; neither was there any thing that could 
have any indammable Vapour there. 
My Surprize was the greater, becaufe all I read 
on that Subjed fays nothing will burn but what 
fends forth fuch Vapours. 
At 9 the fame Evening I made him put on the 
fame Frock, and touch'd the left Arm, where the 
Flax had not been burnt before ; and it had the fame 
Effed as above. 
Sir,
