ted that natural selection may have done something in the formation
of a new species; but this it appears (Ibid., vol. iii. page 798)
is inaccurate and without evidence. I also gave some extracts from a
correspondence between Professor Owen and the editor of the "London
Review", from which it appeared manifest to the editor as well as to
myself, that Professor Owen claimed to have promulgated the theory of
natural selection before I had done so; and I expressed my surprise
and satisfaction at this announcement; but as far as it is possible to
understand certain recently published passages (Ibid., vol. iii. page
798) I have either partially or wholly again fallen into error. It
is consolatory to me that others find Professor Owen's controversial
writings as difficult to understand and to reconcile with each other,
as I do. As far as the mere enunciation of the principle of natural
selection is concerned, it is quite immaterial whether or not Professor
Owen preceded me, for both of us, as shown in this historical sketch,
were long ago preceded by Dr. Wells and Mr. Matthews.
M. Isidore Geoffroy Saint-Hilaire, in his lectures delivered in 1850 (of
which a Resume appeared in the "Revue et Mag. de Zoolog.", Jan., 1851),
briefly gives his reason for believing that specific characters "sont
fixes, pour chaque espece, tant qu'elle se perpetue au milieu des memes
circonstances: ils se modifient, si les circonstances ambiantes viennent
a changer. En resume, L'OBSERVATION des animaux sauvages demontre deja
la variabilite LIMITEE des especes. Les EXPERIENCES sur les animaux
sauvages devenus domestiques, et sur les animaux domestiques redevenus
sauvages, la demontrent plus clairment encore. Ces memes experiences
prouvent, de plus, que les differences produites peuvent etre de VALEUR
GENERIQUE." In his "Hist. Nat. Generale" (tom. ii, page 430, 1859) he
amplifies analogous conclusions.
From a circular lately issued it appears that Dr. Freke, in 1851
("Dublin Medical Press", page 322), propounded the doctrine that all
organic beings have descended from one primordial form. His grounds of
belief and treatment of the subject are wholly different from mine;
but as Dr. Freke has now (1861) published his Essay on the "Origin of
Species by means of Organic Affinity", the difficult attempt to give any
idea of his views would be superfluous on my part.
