Hand of a Man j infomuch that the Sparks, proceed- 
ing from thofe feveral Bodies, will alfo kindle the 
fame Effence. 
If fuch fluid Bodies, as are ufually kindled by Flame, 
are not fine enough, they need only be warm'd a 
little in the Spoon : Or the Spirits may be lighted a 
little before, and blown out again, before they are 
brought to the electrical Body. 
In this manner I have kindled, with the electrical 
Sparks, camphorated Spirits of Wine, coloured with 
Saffron, the common Ejjentia vegetabilis and even 
French Brandy, and Corn-Spirits, only taking the 
Precaution of warming thefe Liquors a little before. 
Even Oil, Pitch, and Sealing-wax, may be lighted 
by the eleClric Sparks, provided they are before 
heated to a Degree that is next to kindling.
