There is no preparation of antimony which has been sub- 
jected to the same amount of study and analytic research as 
Kermes mineral; nevertheless, chemists do not seem to agree 
in regard to its composition. The greater number, and among 
these, MM. Gay Lussac, Liebig, Geiger, Henry, jr., Buch- 
ner, Robiquet, Dunos, Brandes, Bierman, Pagenstecher, and 
others, admit that it is composed chiefly of oxide of antimony, 
united to sulphuret of antimony, whilst Berzelius considers it 
as not differing from common sulphuret of antimony, SbS 3 . 
Some of my own previous experiments correspond with those 
of Berzelius. 
Kermes mineral differs according to its mode of prepara- 
tion. I have examined the kermes as procured by three dif- 
ferent processes.
