Similarly Professor Williamson,[308] speaking of the efforts made to obtain evidence on behalf of Evolution, says: "Not only living, but extinct animals have been appealed to; Professor Huxley especially has, with his wonted skilfulness, made use of the latter to buttress the geological side of the structure, which is confessedly its weakest one." More important than all,--Mr. Darwin himself fully acknowledged that the palæontological evidence is far short of what it should be:--and attempted to meet the difficulty by pleading the imperfection of the geological record:--a plea to be more fully considered presently. We must not leave unnoticed the method of dealing with the geological record adopted by Professor Haeckel. Of this we have already seen a slight specimen,--- in the gratuitous and baseless assertion that the apetalous Dicotyledons date as far back as the Trias, at the very bottom of the Secondary period, by which, were it a fact, a serious Evolutionary void would be filled. In the same manner he draws a perfectly imaginary picture of the submarine forests of primeval days, in which "we may suppose" all the forms of after vegetation to have begun their career as seaweeds.[309] But in regard of his favourite doctrine of the bestial origin of man, he goes much further, and prints[310] an elaborate genealogy upon which Professor Huxley in reviewing him makes no adverse remark. In this he exhibits, as a simple matter of scientific fact, an "Ancestral Series of the human pedigree," which ninety-nine per cent, of his readers will naturally suppose to be based upon palæontological evidence. This wonderful genealogy stands thus: 1. _Monera._ 2. Single-celled Primeval animals. 3. Many-celled Primeval animals. 4. Ciliated planulæ (_Planæada_). 5. Primeval Intestinal animals (_Gastræada_). 6. Gliding Worms (_Turbellaria_). 7. Soft-worms (_Scolecida_). 8. Sack worms (_Himatega_). 9. _Acrania._ 10. _Monorrhina._ 11. Primeval fish (_Selachii_). 12. Salamander fish (_Dipneusta_). 13. Gilled Amphibia (_Sozobranchia_). 14. Tailed Amphibia (_Sozura_). 15. Primeval Amniota (_Protamnia_). 16. Primary Mammals (_Promammalia_). 17. _Marsupialia._ 18. Semi-apes (_Prosimiæ_). 19. Tailed narrow-nosed Apes. 20. Tail-less narrow-nosed Apes (Men-like Apes). 21. _Pithecanthropus_ (Speechless or Ape-like Man). 22. Talking Man.
