_Note_--The only one of these salts known to the old chemists was the sulphite of potash, under the name of _Stahl's sulphureous salt_ So that, before our new nomenclature, these compoundsbase of fixed vegetable alkali, and so of the rest

In this Table we have followed Bergman's order of affinity of the sulphuric acid, which is the saard to the earths and alkalies, but it is not certain if the order be the same for the metallic oxyds--A

SECT XV--_Observations upon Sulphurous Acid, and its Combinations_

The sulphurous acid is forree of oxygenation than the sulphuric acid It is procurable either by burning sulphur slowly, or by distilling sulphuric acid from silver, antimony, lead, en quits the acid, and unites to these oxydable bases, and the acid passes over in the sulphurous state of oxygenation This acid, in the common pressure and teas; but it appears, from the experiments of Mr Clouet, that, in a very low tereat deal as, but as

That thepreviously oxydated, or by procuring oxygen, for that purpose, froeneral and well established fact, which I have perhaps repeated too often Hence, as sulphurous acid is already deprived of great part of the oxygen necessary for foren, than to furnish it to the greatest part of the metals; and, for this reason, it cannot dissolve them, unless previously oxydated by other means From the same principle it is that the reat facility, in sulphurous acid This acid, like theen, and consequently insoluble in sulphuric acid, and in this way forht be led to conclude that there are no metallic sulphites, were it not that the phenomena which accompany the solution of iron, mercury, and some other metals, convince us that these rees of oxydation, during their solution in acids Hence the neutral salt in which the metal is least oxydated must be named _sulphite_, and that in which it is fully oxydated must be called _sulphat_ It is yet unknohether this distinction is applicable to any of the metallic sulphats, except those of iron and mercury
