Experiment LXXV. 



Near half a cubick inch of compound A- 

 qnafcrttSy which bubbled and made a con- 

 siderable cxpanfion in diftillation was foon 

 dualled off: As it cooled the cxpanfion 

 abated very faft, and a little air was abforb- 

 cd. Whence it is evident that the air ge- 

 nerated by the diftillation of nitre, did not 

 arife from the volatile fpirituous particles. 



Hence alfo it is probable that there is 

 ibme air in acid fpirits, which is reforbed 

 and fixt by them in diftillation. And this 

 is further confirmed from the many air bub- 

 bles which arife from Jqua-regia, in 

 the folution of gold 5 for fince gold lofes 

 nothing of its weight in being diflblved, the 

 air cannot arife from the metalline part of 

 the gold, but muft either arife from the 

 Aqua-regia or from latent air in the pores 



• of the gold.
