    covered that the superior nuixilla was a hollow instead of a solid bone. Leeuwenhock (1632-1723) by various iniprovcmonts in the microscope made cousiderabli! pro- gress in dental histology. A decided advancement was made in 1800, in Frank- fort through Fauchard, who is everywhere honored as the father of modern dentistry. In his epoch making work of 1728, Le Chirurgien Dentiste on traite des dents, he laid the foundation for the anatomy, pliysiology, pathology, and therapy of the mouth and teeth. Founded on these fundamentals, there has arisen a massive structure, the materials of which have been collected from all the civilized lands of the world, the structure of the well established, although not yet complete international science of dentistry. COMPARATIVE ANATOMY OF THE TEETH. AVe must not neglect a review of the most important forms of mammalian teeth, as their relationship to the whole skeletal structure is of considerable scientific import- ance. That in doing so we shall be forced to resort to paleontology and to go back to fossil teeth as the sole remains of an extinct fauna, is rather an advantage than otherwise, for the scientific odontologist should not be ignorant of ])alcontology. The teeth of all mammalia, are formed in the nnicous membrane of the mouth ; as their development progresses the alveolar processes of both jaws grow about the teeth thus bringing tluMU in close connection with the skull. Th(y are, however, never join(Hl to the skull by a firm bony growth, for a layer of connective-tissue always remains between the roots of the tooth and the bony structure. The teeth of the majority of the mammals consist of enamel, dentin, and cement. They are hoHow within and contain the tooth pul]) or marrow. Th(> oximcl is a hard substance which usually covers the crown com- pletely. Exceptions to this rule are seen in the incisor
