1 8 i Anahfis of the Air. 



. E X PERI M ENT LXXV. 



Near half a cubick inch of compound A* 

 auafortis^ which bubbled and made a con- 

 iiderabie cxpanfion in diflillation. was foon 

 qiftilted oix: As it cooled the expanfion 

 abated very fail;, and a little air was absorb- 

 ed. Whence it is evident that the air ge- 

 nerated by the diflillation of nitre, did not 

 arife from the volatile fpirituous particles. 



Hence alio it is probable that there is 

 fome air in acid fpirits, which is reforbed 

 and fixt by them in diflillation. Aad this 

 is further confirmed from the many air bub- 

 bles which arife from Aqua ~ regia , in 

 the foliation of gold $ for itnee gold lofes 

 nothing of its weight in being diffolved, the 

 air cannot arife from the metalline part of 

 the gold, but mufl either arife from the 

 Aqua- regia or from latent air in the pores 

 of the gold.
