By methods which need not be described here, the whole of the gas which is in
the flask and exit tube when the experiment is finished is driven into the
graduated cylinder. The white solid in the flask is now weighed; the small quantity
of air in ...

If some finely divided iron is intimately mixed with some powdered sulphur, a
heavy, greenish-grey, solid is formed. This solid cannot be an element; the
method of its preparation precludes this. It is composed of the two distinct kinds of
matter, ...

Neither iron nor sulphur has yet been separated into unlike parts; the methods
which succeed in separating iron sulphide into iron and sulphur fail to separate
iron or sulphur into kinds of matter different from iron or sulphur. Bromine likewise
