tains no water than that is combined with that liquid. I shall use for 
such a case the term anhydrous; anhydrous sulphuric acid must be 
understood to mean sulphuric acid containing no water, aqueous 
sulphuric acid, to mean a compound in definite proportions of the 
acid with water, and dilute sulphuric acid any mixture of the acid 
with water. 
SULPHOSALTS.(61) 
I shall enumerate only the classes of sulphosalts, since the indi- 
vidual salts have a nomenclature corresponding to the similar salts in 
the series of sulphates, which has just been given. 
Sulphohydrates.(62) Sulphocarbonates.(65) | 
Sulphocyanates.(63) Sulphophosphates. 
Sulphocyanhy drates.(64) Sulphophosphites.(66) 
(63) “Those combinations of sulphur with the electro-positive metals which cor- 
respond in composition to the oxybases (viz. those resulting from the action of the 
oxybases and sulphuretted hydrogen on each other,) play the parts of bases in the 
sulphosalts. The combinations containing greater proportions of sulphur do not pos- 
sess this property, and thus resemble the superoxides: they do not combine with 
other sulphurets, but may yield their excess of sulphur to metals. Those compounds 
of sulphur with the electro-negative metals, which correspond to the metallic acids, 
combine with the electro-positive sulphurets, in such proportions that if the sulphur ~ 
were replaced by the same number of atoms of oxygen, we should obtain one of the 
salts formed by the same radicals when combined with oxygen.” ’ 
‘© As the electro-positive oxides sometimes combine with each other, so also cer- 
tain electro-positive sulphurets occasionally unite. Thus the sulphuret of iron unites 
with the sulphuret of copper. Nature affords us many such combinations, in the 
mineral kingdom, occurring in a crystallized form. The composition of most of these 
bodies is such, that by oxidation they become double sulphates.” (Vol. III, p. 334, 
&c.)— Trans. 
(62) Sulphohydrates, or sulphydrates. Compounds of sulphuretted hydrogen with 
metallic sulphurets. ‘‘Sulphuretted hydrogen converts the alkalies, earths, and 
other metallic oxides, into sulphurets. Eight of these, namely, those produced by 
the alkalies and alkaline earths, combine with sulphuretted hydrogen, (hydric sul- 
phide,) forming salts which are soluble in water, &c.” The hydrosulphates of po- 
tassa, soda, ammonia, &c. of the English and French chemists.— Trans. 
(63) Sulphocyanates. Compounds of sulphobases with sulphocyanogen, (cyanous 
sulphide.) See note of Berzelius to cyanous sulphide. This class is not introduced 
in its place, in the third volume; the view taken, in the second volume, of the com- 
pounds of sulphocyanogen, being the reverse of that contained in the note just re- 
ferred to, viz. that sulphocyanogen is a haloid body. (See note 58.)— Trans. 
(64) Sulphocyanhydrates. Compounds of sulphobases with hydrosulphocyanic 
acid. (See note 56.)— Trans. 
(65) Compounds of sulphobases with the carbonic sulphide.— Trans. 
(66) The first (sulphophosphates) obtained by digesting a persulphuret, as for ex- 
ample of potassium, with phosphorus, in a closed vessel. The second, (sulphophos- 
phites) by treating in the same way the quadrisulphuret of potassium.— Trans.
