    i3~Fibroma of Upper Jaw—Left. (One slide.) 14-—Osteoma of Lower Jaw—Right. (One slide.)] II. The second proposition to which I desire to direct your atten- tion may be taken as an almost self-evident fact. The dentist, the scientific worker in dental developmental j^athology. ought .surely to be the most likely man to contribute valuable assistance in elucidating those surgical conditions associated with defective, delayed or aberrant development and maturation of the teeth. I shall confine my remarks to a single department of the field this theme suggests, viz., that concerned with the class of malforma- tions connected with excessive, defeetive, or irregular development of some portion of the primitive tooth-germ. These malforma- tions may, in order to a satisfactory understanding of their rela- tions, be classified under the general term Odontome, though admittedly it is not strictly just to regard certain of the conditions so classified as true odontomes. It may be useful, by way of introducing the subject, if I begin by showing you on the screen a copy of a plate in The Inter- national Text Book of Surgery. This is a photograph of a greatly enlarged and expanded lower jaw in skeleton, taken from a speci- men in the Warren Museum. It is spoken of as illustrating a cystic tumour of the jaw and the statement made is that it is probably dentigerous. I confess that this statement comes to me as somewhat of a surprise. It may be that we are accustomed, in this country, to a too strict application of the term. So far as I can see the specimen presents no unmis- takable evidence of its dentigerous nature. It seems to suggest much more resemblance to the appearance of an osteoma, or an ossifying sarcoma in skeleton. May I show you again the photo- graph of an osteoma of the right lower jaw, and for further compa- rison show you a photographic representation of a skeletonic prepa- ration from that rare affection known as Leontiasis ossium. In this condition which may be termed a local or partial gigan- tism the bones of the skull and face are affected. Thei-e is marked, localised hyperostosis, which in the plate I show you seems to be fairly uniform, the affected bones being lobate or tuberous in out- line. It may be said that the outgrowths are not always luiiform and may affect only one side of the skull or a single bone. The plate from the so-called dentigerous cyst, which I once again show you, might quite well stand, so far as superficial appear- ances go, for a localised form of Leontiasis. The overgrown bony tissue in this condition though generally spongy, is, at times, considerably blown out and expanded so as to present in skeleton an appearance not very different from that shown here. Without further elaboration of the point I may now lay before you what I have to say regarding those tumours directly or indirectly connected with the teeth, many of which are cystic, most of which have the potentiality of presenting cystic characters, and all of which from the point of view of the developmental standpoint furnish interesting material of study. The more immediate reason for my choosing this subject for
