1. J[ HE effects of fire are various. It heats, it shines, 

 t expands, it dissolves other bodies either by melting or 

 educing them to ashes or a calx. Most of these argue 



vehement motion of its particles, which tears asunder 

 whatever it seizes. It seems to be a most subtle mat- 

 er, dispersed throughout the universe. Yet this, even 

 /hen collected soon scatters again, unless it be detained 

 y some inflammable matter. Not that fire will spring 

 roni every motion : it must be circular, as well as ra- 

 id. For if particles move ever so swift in a straight 



ne, no fire will follow.
