JJf/ n "ofa fair fun-ihine, when I found the 



iksS.air jftill better by the nitrous teft ; 



£10>e ' for now one meafure of it with 

 one of nitrous air occupied 0.94 ; 

 and it gave by Abbe Fontana's me^ 



260 thodi.96; 1.87^; 2.44; 3.40. 



It had not, however, loft its ex^

 inverted plant of Perjicaria, fo that 

 the root was in contact with the air ; 

 it flood during fix days in the gar-* 

 den, when I found only 4 of the air 

 remaining, and this was no longer 

 explcfive nor inflammable, but a 

 flame only grew dim in it. >So that 

 roots of water-plants have a re^ 

 markable power of abforbing in~ 

 flammable air, as I found by feveral 

 Other experiments,
