ment. 
Arsenic sulphide. Persulphuret of arsenic.

Chromic sulphuret. 
Suschromic sulphide. 
Molybdous sulphuret.(41) 
of cyanogen requires for complete combustion two ace of sig and yields 
two volumes of carbonic acid and one volume of nitrogen. If one volume of car- 
bonic acid be composed of one volume of vapor of par and one rtune of oxygen, 
then one volume of cyanogen must contain two volumes of the vapor of carbon and 
me volume of nitrogen. Berzelius — -~ the “scene “a carbonic acid, 
one volume of the vapor of carbon and t ming two volumes 
of carbonic acid: that is, he ahablows the eke ppotnatickl wapor e an to be twi 
of cyanogen, but one volume of the vapor of carbon, and makes cyanogen 
pound of equal volumes of the vapor of carbon and of nitrogen, that is, a cacburet tof 
nitrogen, — nitruret.)—T7r 
(33 sulphides, it will be vectlipctid. are Bag oi compounds 0! of sul- 
phur, vinnie the part of acids; Se is, combining with the sulphurets or electro 
compounds, which answer to the bases.— Trans. 
(89) Obtained by passing rlpharte hydrogen through s selenious acid.—Trans 
(40) Subsulphuret of ar: senic. This compound contains only one twelfth part of the 
sulphur mp in the hy Iphide, while the — of arsenic con- 
tains nine times as mu ch sulphur as the hyparsenions sulphide. Such a case is is not 
sg enikhdad for in the new nomenclature, hence the names subsulphuret of 
arsenic and persulphuret of arsenic.—Trans. 
(ai) Berzelius describes three Dae = — with molybdenum, t Be ae 
ase and the two others —_— ive. These latter are the m ge 
Pras clepetchage lic sulphides; the aaa Iphuret. The coportion 
2 : in these compounds ee as 2, 8 and 4, renders probable the crite 
lowet semi, dies anchghsleais oc sulphuret of the table.—Zrans.
