* A combination of cyanic sulphide and hydric sulphide.—Berzelius. 
’ (56) Hydrosulphocyanic acid. An acid “having sulphocyanogen for its radical. 
Sulphocyanogen is a compound of one volume of the vapor of sulphur and one vol- 
ume of cyanogen. Berzelius is disposed to admit the views of Liebeg in relation 
to the existence of sulphocyanogen, as obtained in a solid form by transmitting chlo- 
rine through sulphocyanate of potassa.— Trans. 
t The same components asin the preceding compounds, but containing twice 
the quantity of hydric sulphide.—Berzelius. 
(57) Hydrosulphuretted hydrosulphocyanic acid. ‘The hydrocyanic acid has 
the property, in common with sulphuretted hydrogen, of combining with metallic 
sulphurets, forming salts.” ‘* When these combinations are decomposed by an acid, 
the metal of the sulphuret is oxidized at the expense of the water; thus sulphuret- 
ted hydrogen is produced, which, under favorable circumstances, remains in combi- 
nation with the hydrosulphocyanic acid. Thence results a compound of two hy- 
dracids, analogous to the combinations of certain oxacids, as for example the iodic 
and sulphuric.” 
Beside these compounds of hydrogen, sulphur and cyanogen, Berzelius describes 
(Vol. II, p. 223, &c.) hydrohypersulphocyanic acid and hydrosulphuretted cyano- 
gen. When sulphocyanuret of mercury is heated in sulphuretted hydrogen, or in 
muriatic acid gas, a liquid is obtained which deposits small transparent crystals; 
these erystals are gradually decomposed, liberating hydrocyanic acid, and leaving an 
orange matter which Wohler considers a compound of hydrocyanic acid with twice 
as much gulphur as is contained in hydrosulphocyanic acid. This is the first com- 
pound mentioned above. The second, hydrosulphuretted cyanogen, is obtained 
when cyanogen and sulphuretted hydrogen are presented to each other over water 
or alcohol.— Trans. 
t A substance united with sulphobases in the compounds hitherto called sulpho- 
cyanides, but which appear to be true sulphocyanites.—Berzelius. I have taken the 
liberty to alter the name in the original, which was cyanic sulphide.— Trans. 
(58) After explaining the theory which makes of sulphocyanogen (cyanous sul- 
phide) a haloid body, like cyanogen, Berzelius observes, (Vol. II, p. 220,) “I should 
here remark, that the phenomena afforded by sulphocyanogen and its compounds 
may be differently explained. In fact, the sulphocyanurets may be regarded as sul- 
phosalts in which half the sulphur with the metal constitutes a sulphobase. In this 
view of the subject, hydrosulphocyanic acid would be composed of hydric sulphide 
‘combined with cyanous sulphide ; this latter body not having been insulated, as is 
the case with the boric and silicic fluorides, in their compounds with hydrofluoric
