What I have said about St. George's, in Chapter 7, is much better said in Pelletan's books on _Royan_ and in his _Pasteur du Desert_. That Pastor, as is generally known, was the grandfather of Pelletan, the reverend minister Jarousseau, so admirably heroic in saving his enemies. His small house, still standing, is a veritable Temple of Humanity. Notes to Book 2. Chapter I, _Fecundity_. On the Herring, see Vol. I of De Reste's translation of an anonymous Dutch work; Noël de la Moriniere in his excellent works printed and unpublished; Valenciences' _Poissons_, &c. Chapter II.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. Chapter III. _The Atom._ In the text I have quoted the great masters, Ehrenberg, Dujardin, Pouchet, Heterogenie. In the end spontaneous generation will conquer. Chapters IV., V., VI., &c. Throughout this book, in ascending from inferior to superior life, I have taken for my guiding thread in the great labyrinth, the hypothesis of Metamorphosis but without serious intention of constructing a _chain of beings_. The idea of ascending Metamorphosis is natural to the mind, and is, in some sort, irresistibly imposed upon us. Cuvier himself, at the close of his Introduction to his _Poissons_, confesses that if that theory has no Historical value it _has a logical value_. On the _Sponge_, see Paul Gervais Dict. d'Orb. V. 375; Grant in Chenn, 307, &c. On Polypes, Corals, and Madrepores (Chapters 4 and 5) besides Forster, Peron and Dawin consult Quoy and Gaimard; Lamouroux, _Polypes Flexibles_; Milne Edwards, Polypes and Ascidies of the Channel, &c. On the Calcaire, see the two Geologies of Lyell. Chapter VI. _Medusæ, Polypes, &c._ See Ehrenberg, Lession, Dujardin, &c. Forbes shows by vegetable analogies that these animal metamorphoses are very simple phenomena. Annals of Nat. History, December, 1844. See also his excellent dissertations, _Medusæ_, in quarto, 1849. Chapter VII. _The Oursin or Sea Hedgehog._ See the curious dissertations in which M. Cailland has described his discoveries.
