Dr. ingenhousz on Lighting a Candle , &c. i o 2,3 
has eight or ten inches of metallic coating, or even lefs) 
in the following manner. As I often amufe myfelf with 
electrical experiments, I have always an electrical ma- 
chine, ready for aCtion, fixed upon a table in my room. 
When I have occafion to light a candle, I charge a fmall 
coated phial, whofe knob is bent outwards, fo as to hang a 
little over the body of the phial ; then I wrap fome loofe 
cotton over the extremity of a long brafs pin or a wire, 
fo as to fiick moderately fall to its fubftance. I next roll 
this extremity of the pin, wrapped up with cotton, in 
fome fine powder of refill (which I always keep in readi- 
nefs upon the table for this purpofe, either in a wide- 
mouthed phial or in a loofe paper) ; this being done, lap- 
ply the extremity of the pin or wire to the external coat- 
ing of the charged phial, and bring, as quickly as poffi- 
ble, the other extremity, wrapped round with cotton, to 
the knob: the powder of refin takes fire, and communi-' 
cates its flame to the cotton, and both together burn long 
enough to light a candle. As I do not want more than 
half a minute to light my candle in this way, I find it 
a readier method than kindling it by flint and fteel, or 
calling a fervant. 
I have found, that powder of white or yellow refin 
lights eafier than that of brown..
