Bern, Burgerbibliothek, Cod. 402

...extinguish [it], but oil extinguishes it, because it dissolves, being thinner in relation to the principle. And yet, one might take the most incombustible substance and, by pressing it, extinguish this, just as it happens when poured onto lamps. Again, vinegar is more extinguishing than water for the same reason, as it is the hottest of the rest. For it is destroyed most and to the greatest extent so that it touches the principle. For it is not the case that cold strictly extinguishes the cold. This is clear, because even boiling water, once it is apart, floats upon and covers the principle. When both the moist and the cold are combined, it is destroyed more, for the destruction of opposites occurs by opposites. For fire is hot and dry. Nevertheless, even when separated, each is destructive. For air, being cold, extinguishes, and water, being moist. And these [extinctions] occur by its natural [constituents] and by the opposites, by the opposites; but that which is on its own is like that which is contrary to nature. It is not contrary to nature for the lesser power to be mastered by the greater. Things that are inherently destructive are also destroyed by excesses, unless one has this and it increases as it receives symmetry. For instance, the moist [substance] is itself consumed. And the cold, by pressing it, makes it stronger. And the pneuma spirit/air current, by its motion, burns along with it and keeps it alive. This is why lamps consume more oil in drafts, and woods burn down faster as the motion becomes more violent and greater. But the greater and asymmetrical [motion] extinguished it. And for this reason, a lamp is extinguished when blown upon, but woods and coals are inflamed. For the pneuma is not symmetrical...
Why vinegar is more extinguishing than water.
