    ON THE ORIGIN AND DEVELOPEMENT OP THR PULPS AND SACS OF THE HUMAN TEETH. By John Goodsir, Junior, Surgeon, Anstrutlier, Fifeshire. (From the Edin. Med. and Surg. Journal, No. 138.J II est peu de sujets en medecine sur lesquels on ait tant ecrit que sur les dents; deux cent volumes contiendraient a peine tout ce qu'on en a imprime ! Mais est-ce a dire que tout soit connu a cat egard ? Est-ce a dire que la matiere ait ^te epuisee et qu'il ne restc plus rien a faire ? Nulleraent. L'Anatomie n'a pas encore le der- nier mot de la nature sur cet interessant sujet, et il reste encore, quoiqu'on en dise, quelques doutes a eclaircir et plus d'une difficulte a rdsoudre. Blandin, Anat. du Systeme Dentaire, 1836. Section I.—Examinations of the dental arches at DIFFERENT AGES. T. An embryo (Fig. 1,) whick measured 7^ lines from the ver- tex to the point of the coccyx, weighed 15 grains, and appeared to be about the sixth week, * was selected and prepared for the purpose of examining the state of the palate and dental arches. * It is difficult to determine the exact age of an embryo. The ages given in the text, therefore, must be considered as approximations, being probably rather under- rated. 1 have given a full-sized sketch of the youngest subject in which I have ob- served any of the phenomena of dentition, with the weight and measurements of a •few of the others. In researches of this kind, the sequences of phenomena are of more importance than their periods of appearance.
