The rest of the series is exactly the same as that of the combi- 
nations of oxygen. 
There are, however, differences between the series of compounds 
of sulphur and that of the compounds of oxygen; several metals 
forming more numerous combinations with sulphur than with oxygen. 
Potassium, sedium, and ammonium,(45) the radicals of the alkalies 
(42) The first of these corresponds to the oxide of tungsten, the second to its 
acid.— Trans. 
(43) Although the stannic sulphide alone appears in the table of the original, the 
three compounds introduced into the translation are to be found in the third volume, 
under the head of the compounds of tin and sulphur.—7Trans. 
(44) Aurous sulphuret; obtained by passing a stream of sulphuretted hydrogen 
gas through a solution of the chloride of gold.— Trans. 
(45) ‘“‘ Ammonium combines with sulphur in several proportions; the compounds 
may be obtained by distilling the analogous compounds of sulphur and potassium 
with the ammonic chloride.” ‘In the double decompositions which take place, the 
potassium combines with the chlorine and the ammonium with the sulphur.” “Am- 
moniacal gas is not absorbed by sulphur, because the hydrogen necessary to produce 
the metal (ammonium) is wanting. _If the vapor of sulphur and ammoniacal gas be 
passed together through a red hot tube, one part of the alkali is decomposed, yielding 
its hydrogen to the other part, which is thus converted into. ammonium, and nitrogen 
is liberated. If the products be collected in a receiver, kept at a low temperature, 
fine yellow crystals of sulphuret of ammonium will be produced. The ratio of the 
elements to each other, in these crystals, has not been determined.”—Trans.
