... we conclude that the change which the iron has suffered probably consists in
combination with oxygen. This conclusion has been verified by experiments. A
weighed quantity of finely divided copper is dissolved in moderately concentrated

But we know that nitric acid is entirely volatilised by heating in an open dish ;
hence we conclude that in the reaction between the two kinds of matter, tin and
nitric acid, the tin has probably laid hold of some constituent or constituents of the
...

The properties of every mixture probably differ slightly from the sum of the
properties of its constituents; some change occurs in the formation of the mixture;
nevertheless the properties of each kind of matter in the mixture are so slightly ...

... any element which is known to combine with oxygen is burnt in an enclosed
volume of air, the whole or a part of the oxygen in the air will combine with the
element, and the air which remains will most probably differ from the original air.
