One sees with an interest such as only these homological researches could ex- cite, that they were distinctly developed in the ancient Amphicyon {fig. 576.), which ac- cordingly presents the typical formula. Thus, I repeat, the study of the relative position of the teeth of the bear might have led to the recognition of their real nature and homolo- gies, and have helped to raise the mask of their extreme formal modifications, by which they are adapted to the habits of the more blood- thirsty Carnivora. But the truth is plainly and satisfactorily revealed when we come to trace the course of development and succes- sion of these teeth. The weight which must ever attach itself to an opinion sanctioned by the authority of both the Cuviers, demands that a conclusion contrary to theirs, and which seems to be opposed by Nature herself in certain instances, should be supported by all the evidence of which such conclusion is susceptible. I proceed, therefore, to show how, in the bear, my determinations of the teeth are es- tablished by their development, as well as by their relative position. As the question only concerns the molar series, the remarks will be confined to these. In the jaws of the young bear, figured in cut 581., the first premolar, p. 1, is the only one of the permanent series in place; similarity to p. 4 in the lower jaw (Jig. 581, URSUS), to be veritably the last of the pre- molar series, and to agree not in shape only, but in every essential character, with the three preceding teeth called by Cuvier "fausses ; So, likewise, in the lower jaw, we see that the primitive deciduous serie
