It hasan extraordinary clinical history:— A man, aged 36 years had a large osseous tumouroccupying the antrum. The pressure of this tumourhad caused the front wall of the antrum, with the integu-ment and soft tissues covering it, to slough. The troublewas first noticed thirteen years before: as the cheek en-larged the eyeball became displaced and finally burst. Fora long time the surface of the tumour was exposed, thesuppuration being co]3ious, and occasionally pieces of bone. Fig. 131.—Composite odontome from the iipi^er jaw. (Ji^at. size.) irregular in shape came away; at last, to the mans astonish-ment, the bony mass drojaped out, leaving an enormous holein his face. It weighed nearly 15 ounces, and measured275 cm. (11 inches) in its greatest circumference. I have hadan opportunity of investigating this tumour ; it is remarkablyhard, presents on section an ivory-like surface, and, on closescrutiny, a number of closel}^-arranged concentric laminae(Fig. 134). Sections ground thin and examined under themicroscope show large numbers of lacume and canaliculiarranged in a veiy regular manner. On looking over a long series of composite odontomas itis curious to find the great variety in shape, as well as in the
