The compressed conical crowns of the molar teeth of the small clawed seals (Sfenorhi/nchus) are divided either like a trident, into three sharp points, or like a saw, into four or five points ; the molars of the great extinct Zeuglodon had a similar form ; such teeth have been called den'es serrali. But the philosophical course of the knowledge of nature tends to explode needless terms of art, invented for unimportant vari- eties, and to establish and fix the meaning of those terms that are the signs of determinate species of things. The Cuviers divided the molar series of teeth, according to their form, into three kinds: "false mo- lars," " carnassials," and " tubercu- lar molars ; " and, in giving the ge- neric characters of Mammalia, based the dental formula? on this system : thus the genus Felis is characterised 2 2 as having <: fausses molaires TEETH. cavnassieres 1—1, 1—1 2—2 tuberculeuses 1—1 8 (3' 0—0' The uninterrupted line marked " Cuvier" in V. FELIS of fig. 580., intersects the teeth in each jaw called carnassieres; those anterior to them being the teeth called " fausses molaires ;" the single tooth behind in the upper jaw is the " tu- berculeus
