FOOTNOTES:
[1] As the works of the first-named authors are so well known, I need not give the titles; but as those of the latter are less well known in England, I will give them:—‘Sechs Vorlesungen über die Darwin’sche Theorie:’ zweite Auflage, 1868, von Dr. L. Büchner; translated into French under the title ‘Conférences sur la Théorie Darwinienne,’ 1869. ‘Der Mensch, im Lichte der Darwin’sche Lehre,’ 1865, von Dr. F. Rolle. I will not attempt to give references to all the authors who have taken the same side of the question. Thus G. Canestrini has published (‘Annuario della Soc. d. Nat.,’ Modena, 1867, p. 81) a very curious paper on rudimentary characters, as bearing on the origin of man. Another work has (1869) been published by Dr. Barrago Francesco, bearing in Italian the title of “Man, made in the image of God, was also made in the image of the ape.”
[2] Prof. Häckel is the sole author who, since the publication of the ‘Origin,’ has discussed, in his various works, in a very able manner, the subject of sexual selection, and has seen its full importance.
[3] ‘Grosshirnwindungen des Menschen,’ 1868, s. 96.
[4] ‘Leç. sur la Phys.’ 1866, p. 890, as quoted by M. Dally, ‘L’Ordre des Primates et le Transformisme,’ 1868, p. 29.
[5] ‘Naturgeschichte der Säugethiere von Paraguay,’ 1830, s. 50.
[6] Brehm, ‘Thierleben,’ B. i. 1864, s. 75, 86. On the Ateles, s. 105. For other analogous statements, see s. 25, 107.
[7] With respect to insects see Dr. Laycock ‘On a General Law of Vital Periodicity,’ British Association, 1842. Dr. Macculloch, ‘Silliman’s North American Journal of Science,’ vol. xvii. p. 305, has seen a dog suffering from tertian ague.
[8] I have given the evidence on this head in my ‘Variation of Animals and Plants under Domestication,’ vol. ii. p. 15.
[9] “Mares e diversis generibus Quadrumanorum sine dubio dignoscunt feminas humanas a maribus. Primum, credo, odoratu, postea aspectu. Mr. Youatt, qui diu in Hortis Zoologicis (Bestiariis) medicus animalium erat, vir in rebus observandis cautus et sagax, hoc mihi certissime probavit, et curatores ejusdem loci et alii e ministris confirmaverunt. Sir Andrew Smith et Brehm notabant idem in Cynocephalo. Illustrissimus Cuvier etiam narrat multa de hac re quâ ut opinor nihil turpius potest indicari inter omnia hominibus et Quadrumanis communia. Narrat enim Cynocephalum quendam in furorem incidere aspectu feminarum aliquarum, sed nequaquam accendi tanto furore ab omnibus. Semper eligebat juniores, et dignoscebat in turba, et advocabat voce gestuque.”
