Near half a cubick inch of compound A- 
qua- fort is, which bubbled and made a con- 
fidcrable expanfion in diftillation was foon 
diflilled off : As it cooled the expanfion 
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 
ariie from the volatile fpirituous particles. 
Hence alfo it is probable that there is 
fome 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 Aqua - 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 miift either arife from the 
A qua- regia or from latent air in the pores 
of the gold.
