24 On new Combinations of Oxygen and Acids. 
no action on gold at the ordinary temperature, at least in the space 
of a few minutes. With silver it occasions as lively an efferves- 
cence as when an acid is poured on a carbonate; because water 
and chlorine being formed by the reaction of the oxide and the 
muriatic acid on each other, the oxygen united with the acid be- 
ing suddenly disengaged assumes the gaseous form, 
This property of the oxygenized muriatic acid being decom- 
posed by oxide of silver, liberating the oxygen, may probably 
enable us to form several other oxygenized acids with facility. 
Thus, with this acid and a solution of fluate of silver we may ex- 
pect to obtain oxygenized fluoric acid. 
In oxygenized muriatic acid the hydrogen and oxygen are in 
the proportions required to form water. 
These, which are the principal results that I have hitherto ob- 
tained, make us acquainted with a new class cf bodies, which 
may probably prove numerous in species. We must discover 
them, ascertain their properties, and the different circumstances 
in which they are capable of being formed; and see whether 
other bodies, besides acids, be not capable of combining with 
oxygen. A laborious set of experiments is thus chalked out, the 
results of which shall be laid before the Academy. « 
I have, since these observations were read, satisfied myself that 
by the process pointed out to obtain oxygenized fluoric acid, not 
only this, but likewise oxygenized sulphuric acid, may be ob- 
tained. Indeed all the acids susceptible of being oxygenized may 
easily be procured in that way. Oxygenized fluoric acid does 
not give off its oxygen at a boiling temperature, but oxygenized 
sulphuric acid parts with it easily. . ; 
I have also ascertained that oxygenized nitric and muriatic 
acids may be combined with new doses of oxygen; as is proba- 
bly the case with the other acids. To obtain these new com- 
pounds, it is only necessary to treat the oxygenized acid with the 
deutoxide of barium, as stated above: thus to superoxygenize 
oxygenized muriatic acid, saturate this acid with deutoxide of 
barium. The sulphurie acid precipitates the barytes, and the li- 
quid is then decanted off, which will be found to contain all the 
oxygen furnished by the two portions of deutoxide of barium on 
which the operation is performed. 
It deserves to be noticed, that the same acid may be repeat- 
edly oxygenized by the same process. 1 have oxygenized it as 
often as seven times. 
Whether these kinds of combinations take place in definite or 
indefinite proportions, must be ascertained by future experiments. 
But however this may be, when an excess of barytes water’ is 
poured on the oxygenized nitric or on the oxygenized muriatic 
acid, or into these acids superoxygenized, an abundant crystal-
