In these two cases we say that they are not the relations of aflinity of one body to another, but afiinities of concourse, otherwise called double afinities; in a word, the sum of all the united aflinities which are needed to explain these phenomena.

This tendency to supercomposition, is sometimes so strong, that when the least affinity of a third body interferes with it, the proportions of the first compound are changed, and the neutral state destroyed. This tendency may cause the production of crystals, with excess of base, in an acid liquor. To distinguish this force, we shall call it the aflinity of a compound for an excess of one of its constituents, or for shortness, afinity qfezvcess, which will be enough to recall the idea when it has been well grasped. However paradoxical some of these propositions may appear, I have no fear of their being called in question after the proofs I have given; and if they are well founded, it will readily be granted that they ought to form one of the most important elements in the calculation of aflinities."
