Or , assuming that the water was indeed changed in this experiment into the two
gases called hydrogen and oxygen , we ask ; what definite meaning is to be put
upon the statement water can be changed into hydrogen and oxygen ?

burnt in air under conditions such that the whole of the magnesia produced in the
burning remains in the vessel in which the burning proceeds . The apparatus ...
