    root, in noticing exactly the appearance and duration of each of these chang-es that it under- g-oes, we may disting-uish old subjects by prin- ciples nearly as certain as those founded on their first appearance, and the obliteration of the mark in them. Besides, the direction of the teeth, and the shape of their table, furnishes important approximations to rectify variations ; and these approximations become particularly useful after the destruction of the dental funnel, for its root is not always very pronounced, or perfectly distinct. Professor Pessina, of Vienna, explains the g-radations of years beyond eight years old uniformly by the shapes that the in- cisors put on, according as they wear : he has disting-uished four successive periods, the oval, the round, the triang-ular, and the biang-ular. His considerations are very extended, and per- haps too minute; are capable of acquiring* much g-reater importance, and exhibiting* more accuracy, if he had paid attention to the marks * that remain after the obliteration of the marks; and if he had established all the points of com- parison that could lead him with more certainty to the truth. In this present treatise, we have made all the approximations, and the deductions have been founded as much on the shape and direction of the teeth, as on the different shades of the central enamel and its root.
