and make way for one another > there will not follow any 

 great cffe& in this kind: as we fte in bottled beer or ale, that 

 worketh little, unlcfle there be fome fpace left empty, in the 

 bottle. And again; if the veflfell be very much to big for the li- 

 quour in it, the fiery parts find room, fiifi to fwell up the hea-. 

 vy oiicsjand at the length to get out from them. though the ve- 

 fel be clofe topped; for they have fcope enough to float up and 

 down between the furface of the liquour, and the roof of the 

 vcfiel. 



And this is the realbn that if a little beer or fmall wine be 

 lefc long in a great cask, be it never fo clofe flopped, it will in 

 time grow dead. And then, if at the opening of the bung ( a- 

 ner the cask hath been long unftirred ) you hold a candle clofc 

 to kj you fhall at the inftant fee a fla(h of flame environing the 

 vent. Which is no other thing, but the fubtile (piths that part- 

 ing from the beer or wine, have left it dead; and flying abroad 

 as foo as they are permitted, are let on fire by the flam* thae 

 they meet with in their jeurney, a* being morecombuftible(bc- 

 caule more fubtile) then that fpirit of wine which is kept in form 

 of Hquour : ajid yet that likewife ( though ipuch groffer ) is fee 

 on fire by the toeh of flame, And this happeneth not onely to 

 wfie, tnd beer, or ale, but even to water. As dayly experience
