fore a Mediterranean race already existed 12,000 years ago. But what space of time was requisite to enable primitive man to separate into races, is entirely beyond computation, and the more so as not the slightest trace of him has hitherto been found. With the invariable testimony of Geology that the periods of the terrestrial strata imperceptibly merged into one another, and that, especially from the Tertiary, through the Diluvial period, to the present age, continuity has been only locally interrupted, the question of the "fossil man," formerly looked upon as cardinal, has assumed another aspect. In Europe, man lived with the mammoth and the rhinoceros with a bony nasal partition (Elephas primogenius, Rhinocerus tichorhinus). It has been asserted that European man existed as early as the upper Tertiary age, but the evidence is disputable. Such remains as we have of this oldest man known to us, display a high grade of development, and certainly belong to the period at which man had already found in language the implement wherewith gradually to free himself from the dross of his lowly origin. Whether the primitive man be found or not, his origin is certain. REFERENCES AND QUOTATIONS. 1 Luthardt, Apologetische Vorträge. 7 Vortrag.

Also another small work of mine: "Goethe's Verhältniss zu den organischen Naturwissenschaften" (Berlin, 1852). To the passages given in the text, which might make Goethe appear as a Darwinist, I may add the following from Eckermann's “ Gespräche mit Goethe" (3 Ed. p. 191). "Thus man has in his skull two empty cavities. The question why? would not go far, whereas the question how? teaches me that these cavities are remains of the animal skull, which in those inferior organisms exist to a greater degree, and are not entirely lost even in man, notwithstanding his higher elevation." 29 A somewhat depreciative opinion of Goethe's importance in this sphere is pronounced by V. Carus in his "Geschichte der Zoologie" (München, 1872). The reader may compare: "How little, notwithstanding his repeated study of anatomy, he had gained a true insight into the structure of animals, as determined by law, is testified by his Introduction to Comparative Anatomy. He finds no other means of harmonizing the dry details of descriptive anatomy, and the morphology which vaguely hovered before him, but by indicating the idea of a primitive type for animals, which he is, however, unable to define or to render in any way palpable by more general indications. His whole idiosyncrasy made such a type a necessity to him, not scientifically, but æsthetically," etc. P. 590. 30 R. Owen has declared his attitude towards the doctrine of descent in the concluding chapter of his "Manual of the Comparative Anatomy of the Vertebrata." It is published separately under the title of "Derivative Hypothesis of Life and Species," 1868. a1 Ib....."such cause being the servant of predetermining intelligent will." 32 “No one can enter the saddling-ground at Epsom before the start for the Derby, without feeling that the glossy-coated, proudlystepping creatures led out before him are the most perfect and beautiful of quadrupeds. As such, I believe the horse to have been predestined and prepared for man.” Ib. P. II. 33❝I deem an innate tendency to deviate from parental type, operating through periods of adequate duration, to be the most probable nature or way of operation of the secondary law whereby species have been derived one from the other." Ib. P. 22. 34 Lamarck, Philosophie Zoologique (Paris, 1809). In the text allusion is made to the following passages :-- "Ainsi l'on peut assurer que, parmi ses productions, la nature n'a réellement formé ni classes, ni ordres, ni familles, ni espèces constantes, mais seulement des individus qui se succèdent les uns aux autres, et qui ressemblent à ceux qui les ont produits. Or ces individus appartiennent à des races infiniment diversifiées, qui se nuancent sous toutes les formes et dans tous les degrés d'organisation, et qui chacune se conservent sans mutation tant qu'aucune cause de changement n'agit sur elles." I. 22. "La supposition presque généralment admise, que les corps vivans constituent des espèces constamment distinctes par des caractères invariables, et que l'existence de ces espèces est aussi ancienne que celle de la nature même, fut établie dans un temps où l'on n'avait pas suffisament observé, et où les sciences naturelles étaient à peu près nulles. Elle est tous les jours démentie aux yeux de ceux qui ont beaucoup vu et qui ont longtemps suivi la nature." I. 54. "Les espêces n'ont réellement qu'une constance relative à la durée des circonstances dans lesquelles se sont trouvés les individus qui les représentent." I. 55. |
