Extract

The interest awakened by Gay-Lussac's great discovery of the simplicity in the relation of the volumes of gases has greatly increased in recent times, when chemists have discovered that, in a large number of instances at least, the formula of a body, as deduced physically from its vapour density, exactly coincides with that deducible from chemical considerations of its reactions, and from the nature of the products arising in consequence of them.

The processes at present used for determining the vapour densities of bodies, are those of Gay-Lussac and Dumas.
