acetate of iead. When it is converted into gypsum, it is still said 
to be desulphuretted, although it contains sulphuric aci 
int seems now to be virtually admitted even by Liebig, 
as through Feitmann’s paper an entirely new issue is joined, and 
the old one left untouched. Fleitmann’s researches, made in the 
Giessen Laboratory, showed that protein, when burned with nitre, 
ields a weighable ES os ap cee acid. ‘This was true, 
but still it had nothing to the original question. In con- 
sequence of Fleitmann’s one, “Mulder found himself obliged to 
review the entire protein question, the fact noticed by Fleitmann 
being one which he had overlooked. 
This review is still proceeding, but already some results have 
been arrived at, which seem likely to place Mulder’s name even 
higher than it has stood before. He considers “that albumen, 
horse and cow hoofs, &c. contain sulphur in the state of sulphu- 
ret of amid (SNH? ),—that protein from albumen contains va- 
riable traces of hyposulphurous acid, S*O2, in weighable quanti- 
ties—that this acid is produced by the decomposition of two 
equivalents of sulphuret of amid (SNH?), which by the influ- 
ence of alkali and two equivalents of water (2HO), produce an 
equivalent of hyposulphurous acid and two equivalents of am- 
monia (S*O? and 2NH*),—that therefore protein yields variable 
are of hyposulphurous acid, and consequently contains the 
sulphur under a form which has nothing in common with that. 
in which it originally existed,—that cow horns and fibrin consist 
of sulphuret of amid (SNH?) with a body differing from protein 
only in the proportion of oxygen.” 
Hitherto, as Mulder acknowledges, he has been unable to sep- 
arate from protein the last traces of this hyposulphurous acid, 
neither has he or any one else been able to separate the last traces” 
of incombustible substances. He considers that the one no more 
belongs to the formula of protein than the other, and deducts the 
sulphur as sulphuret of ami 
The following are the results obtained i in this way from albumen.
