300 Analyjis of the Air. 



pofely made, that a Candle, which burnt jo'' 

 in a very dry receiver, burnt but 64" in the 

 fame receiver, when filled with the fumes of 

 hot water j and yet abforbed one-fifth part 

 more air, than when it burnt longer in the 

 dry air. 



Sulphur not only abforbs the air when 

 burning in a homogeneal mafs, but alfo in 

 many fermenting mixtures ; and as Sir Ifaac 

 Newton obferved the attractive and refractive 

 power of bodies to be greater or lefs, as they 

 partook more or lefs of fulphureous oily par- 

 ticles j fo there is good reafon from thefe Ex- 

 periments to attribute the fixing of the ela- 

 ftick particles of the air to the ftrong attra- 

 ction of the fulphureous particles, with which 

 he fays it is probable that all bodies abound 

 more or lefs. Electrical bodies are alfo ob- 

 ferved to attract more ftrongly, in proportion 

 to the greater quantity of fulphur which they 

 contain. 



That great plenty of air is united with 

 fulphur in the oil of vegetables, is evident, 

 from the quantity of air that arofe from the 

 diflillation of oils of Anniieeds and Olives, in 

 Exper. 62. When by fermentation the con- 

 ttituent parts of a Vegetable are feparated, 

 part of the air flies off in fermentation into
