PEDIGREE AND HISTORY OF THE ANIMAL KINGDOM. 
III, VERTEBRATE ANIMALS. 
The Records of the Creation of Vertebrate Animals (Comparative Anatomy, 
Embryology, and Palzontology).—The Natural System of Vertebrate 
Animals.—The Four Classes of Vertebrate Animals, according to Lin- 
nzeus and Lamarck.—Their increase to Nine Classes.—Main Class of the 
Tube-hearted, or Skull-less Animals (the Lancelet)—Blood Relationship 
between the Skull-less Fish and the Tunicates.—Agreement in the Em- 
bryological Development of Amphioxus and Ascidiz.—Origin of the 
Vertebrate Tribe out of the Worm Tribe.—Main Class of Single- 
nostriled, or Round-mouthed Animals (Hag and Lampreys).—Main 
Class of Anamnionate Animals, devoid of Amnion.—Fishes (Primeval 
Fish, Cartilaginous Fish, Osseous Fish).—Mnud-fish, or Dipneusta.—Sea 
Dragons, or Halisauria.—Frogs and Salmanders, or Amphibia (Mailed 
Amphibia, Naked Amphibia).—Main Class of Amnionate Animals, or 
Amniota.—Reptiles (Primary Reptiles, Lizards, Serpents, Crocodiles, 
Tortoises, Flying Reptiles, Dragons, Beaked Reptiles).—Birds (Feather- 
tailed, Fan-tailed, Bush-tailed). 
Not one of the natural groups of organisms—which we have 
designated as tribes, or phyla, on account of the blood- 
relationship of all the species included in them—is of such 
great and exceeding importance as the tribe of Vertebrate 
Animals. For, according to the unanimous opinion of all 
zoologists, man also is a member of the tribe; and his whole 
organization and development cannot possibly be distin- 
guished from that of other Vertebrate animals. But as trom
