In the basal portion, the vertebrae are likewise few, are united firmly together, and are arrested in development; but they have been rendered much broader and flatter than the corresponding vertebrae in the tails of other animals: they constitute what Broca calls the accessory sacral vertebrae.
Morgan listened, sweating in the desperation of his plight. They had taken him away from the main part of town, as he was aware by the sound of its revelry in the near distance. Close at hand a railroad engine was frying and gasping; farther off another was snorting impatiently as it jerked the iron vertebrae of a long freight train.
Again, the more ancient Crocodilia and Lacertilia have vertebrae with the articular facets of their centra flattened or biconcave, while the modern members of the same group have them procoelous.
And Georges Hanquet, attacked by softening of the spinal marrow, passes without transition from agony to perfect health; while Leonie Charton, likewise afflicted with softening of the medulla, and whose vertebrae bulge out to a considerable extent, feels her hump melting away as though by enchantment, and her legs rise and straighten, renovated and vigorous.
If these zoologists see in us nothing more than a mammal with thirty-two vertebrae possessing the hyoid bone and more folds in the hemispheres of the brain than any other animal; if in their opinion no other differences exist in this order than those produced by the influence of climate, on which are founded the nomenclature of fifteen species whose scientific names it is needless to cite, the physiologists ought also to have the right of making species and sub-species in accordance with definite degrees of intelligence and definite conditions of existence, oral and pecuniary.
The fates are turning upon Texas an unkindly eye. She is o'erwhelmed quite, sunk in the Serbonian bogs of dark despair. First our mighty Democratic majority slipped up on the Hoggeian banana peel and drove its vertebrae through the crown of its convention plug, while unfeeling Populists and Republicans jeered and flouted us.
In the first place, as regards structural characteristics, I endeavoured to show you, by the skeletons which I had upon the table, and by reference to a great many well-ascertained facts, that the different breeds of Pigeons, the Carriers, Pouters, and Tumblers, might vary in any of their internal and important structural characters to a very great degree; not only might there be changes in the proportions of the skull, and the characters of the feet and beaks, and so on; but that there might be an absolute difference in the number of the vertebrae of the back, as in the sacral vertebrae of the Pouter; and so great is the extent of the variation in these and similar characters that I pointed out to you, by reference to the skeletons and the diagrams, that these extreme varieties may absolutely differ more from one another in their structural characters than do what naturalists call distinct SPECIES of pigeons; that is to say, that they differ so much in structure that there is a greater difference between the Pouter and the Tumbler than there is between such wild and distinct forms as the Rock Pigeon or the Ring Pigeon, or the Ring Pigeon and the Stock Dove; and indeed the differences are of greater value than this, for the structural differences between these domesticated pigeons are such as would be admitted by a naturalist, supposing he knew nothing at all about their origin, to entitle them to constitute even distinct genera.
If you attentively regard almost any quadruped's spine, you will be struck with the resemblance of its vertebrae to a strung necklace of dwarfed skulls, all bearing rudimental resemblance to the skull proper. It is a German conceit, that the vertebrae are absolutely undeveloped skulls. But the curious external resemblance, I take it the Germans were not the first men to perceive.
Within a few inches of the surface, and buried in a bed of shells and petrified fish, our old missionary, Padre Antonio, digged up fifty-one vertebrae quite whole and well preserved. They were mostly from twelve to eighteen inches in length and from eight to fourteen inches in diameter, measuring in all more than fifteen feet in length.
There are great differences, too, in the size of the female and the male, the shape of the body, the number and width of the processes of the ribs, the development of the ribs, and the size, shape, and development of the breastbone. We may notice, too and I mention the fact because it has been disputed by what is assumed to be high authority, the variation in the number of the sacral vertebrae.
