The fundamental idea of the classification of Fitzingeris the same as that upon which Oken has based his sys-tem. The higher divisions, called by him provinces,grades, and cycles, as well as the classes and orders, areconsidered as representing either some combination ofdifferent systems of organs, or some particular system oforgans, or some special organ. His two highest groups(provinces) are the Evertebrata and Vertebrata. TheEvertehrata represent the systems of the vegetative organs,and the Vertebrata those of the animal organs, as the Gut-animals and the Flesh-animals of Oken. Instead, how-ever, of adopting, like Oken, anatomical names for his
