Note 487 — Chapter IX · ON CONCRETIONS, SPICULES, AND SPICULAR SKELETONS (continued 2)
Reading edition
The “bourrelet” is not only, as Plateau expresses it, a “surface of continuity,” but we also recognise that it tends (so far as material is available for its production) to further lessen the free surface-area. On its relation to vapour-pressure and to the stability of foam, see FitzGerald’s interesting note in Nature, Feb. 1, 1894 (Works, p. 309).
