FREEZING OF WATER. 41 



it is not more pure but confiderably lefs fo, and it is per- 

 fedly free from acidity. 



I v>rould farther obferve that thefe experiments, which 

 prove the converfion of water into phlogifticated air, are 

 inconfiftent with the antiphlogiftic theory, which makes 

 water refolvable into dephlogifticated and inflammable 

 air ; but that they are highly favourable to the hypothefis 

 of water being the bafis of every kind of aii", the differ- 

 ence between them depending upon the addition of fome 

 principles which we are not able to afcertain by weight. 

 Alfo, if any fpecies of air be entitled to the appellation 

 «f hydrogen^ it is phlogifton, and not inflammable air.
