the metho,1 of infinitefimals, the e1tmeot, by
which any quantity increafes or decreafes, is fuppofed
tObe infinitely fmall, and is generally exprelfed by
tWOor more terms, fome of which are infinitely lefs
than ¡he ren, which being negle8ed asof no importance,
¡he remaining terms form what is called the differenee
of the propoCed quantity, T he terms that are neglec.
ted in this manner, as infinitely lefs than the other
terms of the element, are the very fame which arife iD
confequenee of the acceleration, or retardation, of the
generating motioo, during the infinitcly fmall time in
which the clemen! is geoerated; fo that the remaining
terms exprefs the clemeots that would have been pro·
duced io that time, ifthe
gen~r.ting
motion had conli·
nued uniform: thmfore thoCe differeoces are accurately
io the fame ratio tO eaeh other as the generating moti·
oos or ftuxions . And henee, though in this method
