Fit quoque ut interdum venti vis missa sine igni igniscat tamen in spatio longoque meatu, dum venit, amittens in cursu corpora quaedam grandia quae nequeunt pariter penetrare per auras; atque alia ex ipso conradens aere portat parvola, quae faciunt ignem commixta volando, non alia longe ratione ac plumbea saepe fervida fit glans in cursu, cum multa rigoris corpora dimittens ignem concepit in auris.
It happens also at times that a force of wind sped forth without fire, yet takes fire in its long journey through space, losing in its course as it comes on certain bodies too large to pass equally well through the air, and scraping together from the air itself and carrying with it other very small bodies, which commingled together with it produce fire during the flight; in much the same way as a leaden bullet often grows hot in its course, when casting off many bodies of coldness it catches fire in the air.
