Definition of "deflux"

The cause is a temperate conglutination ; for both bodies are clammy and viscous , and do bridle the deflux of humours to the hurts , without penning them in too much

By the first deflux the ridges of the waves will dilate themselves this way and that way, and be propagated towards KL and NO. And because the motion of the waves from A towards PQ is carried on by a continual deflux from the ridges of the waves into the hollows next to them, and therefore cannot be swifter than in proportion to the celerity of the descent; and the descent of the water on each side towards KL and NO must be performed with the same velocity
