Chapter II. _Milky Sea._ Bory de Saint Vincent, _Diet. Classique_,

Articles _Mer et Matieres_; Zimmerman, the _World before Man_, a beautiful and popular work which is in every one's hands. I am indebted also to the work of M. Bronn, crowned by the _Academy of the Sciences_. On the universal innocuousness of the vegetation of the Sea, consult Pouchet's _Botanique_ a work of the highest order. For the plants which become animals; see Vaucher's Conferves, 1803; Decaisne and Thuret _Annales de Sc. Nat._, 1845; Volumes III., XIV. and XVI., and _Comptes de l'Acad._, 1853, Vol. XXXVI.; also, articles of Montagne Dict d'Orb. On the Volcanoes, see part 4, of Humboldt's Cosmos, and Ritter, translated by Elisee Reclus, _Revue Germ._, 30th November, 1859.
