A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . connecting structure between the teeth and the bones proper. He should also be thoroughly conversant with the physiology of this region and with the pathological changes of which it may become the seat. Typical vs. Actual Anatomy and Occldsion After close study of the forms of various bones of the human skeleton, bothdisarticulated and articulated, and the open spaces of the face, such as the oralcavity, the orbits, the nasal chamber with its associated pneumatic sinuses andcells, etc., the writer came to the conclusion that typical anatomy as taught intextbooks is more ideal than true, and is something different from that with whichthe surgeon comes into daily contact, and it is his opinion that this divergenceapplies to a notable extent in reference to the jaws and teeth at rest and in occlusion. In order to bear out this statement a few illustrations will be given showingthe typical anatomy of the external and internal structures of the jaws and theocclusion of the teeth. Fig. Upper and lower jaws of a negro skull, showing considerableprognathism. The illustration Fig. 14 is from a slide kindly loaned by Dr. I. N. Broomell,from a photograph of a negro skull which is in his possession. The reason forshowing this picture is the fact that various authors give it as an illustration ofnormal occlusion of the teeth, omitting to state that it is from the negro race—in 70 PART III. BASIC PRINCIPLES OF PRACTICE other words, that it belongs to a race more or less prognathic. The occlusion ofthe anterior teeth shows that it belongs to this type of skull; it is a fine specimen,except that the upper second and third molars do not occlude typically with thelower third molars, even according to the negro type. Fig. 15 is a side view made from an almost perfect skull of a white teeth are so nearly typical in occlusion that but a fev/ persons have
