The American bison is saved from being wholly extinct as a wild animal by the remnant of about 300 head in northern Athabasca, and 49 head in the Yellow-stone Park. It is a serious thing to exterminate a species of any of the vertebrate animals.
When these Dualistic philosophers are consistent they must assign a moment in the phylogeny of the human soul at which it was first "introduced" into man's vertebrate body. I need not insist on the enormous theoretical difficulties of this idea.
And because man is a vertebrate, having an internal, jointed, bony skeleton, man stood in a glass case behind the oracular priestess of the place, in awful, articulated, bony whole, from which the newly initiated had constantly to drag their fascinated, shuddering gaze.
These animals are of the vertebrate sub-kingdom, but of its lowest class next after fishes, namely, reptiles, a portion of the terrestrial tribes whose imperfect respiratory system perhaps fitted them for enduring an atmosphere not yet quite suitable for birds or mammifers.
The development of the individual from the egg to maturity was uninterrupted by any metamorphosis, such as that of the frog when it passes from the tadpole stage. Yet in advancing from the amphibian to the reptile the evolution of the vertebrate was far from finished.
But the forms of life in the two higher vertebrate classes are Nature's most perfect work; and the life of even a single species is of incalculably greater value to mankind, for what it teaches and would continue to teach, than all the chiselled marbles and painted canvases the world contains; though doubtless there are many persons who are devoted to art, but blind to some things greater than art, who will set me down as a Philistine for saying so.
These modifications do not concern us, as they depend on special adaptations, and do not affect the hereditary vertebrate type. When the free-swimming Amphioxus-larva is three months old, it abandons its pelagic habits and changes into the young animal that lives in the sand.
The Amphioxus, which modern science now almost unanimously regards as the real Primitive Vertebrate, the ancient model of the original vertebrate structure, is, according to Dohrn, a late, degenerate descendant of the stem, the "prodigal son" of the vertebrate family.
No remains, however, of them or of any vertebrate animal have yet been discovered in the Ordovician strata, rich as these are in invertebrate fossils, nor in the still older Cambrian; so that we seem authorised to conclude, though not without considerable reserve, that the vertebrate type was extremely scarce, if not wholly wanting, in those epochs often spoken of as "primitive," but which, if the Development Theory be true, were probably the last of a long series of antecedent ages in which living beings flourished.
Wars and fightings come upon us, not through matrimony so much as through the manifold infirmities of mortal nature. John, albeit not a woman, is a vertebrate human being, "with hands, organs, dimensions, senses, affections, passions. If you prick him he will bleed, if you tickle him he will laugh, if you poison him he will die."
