The etiology of osseous deformities of the head, face, jaws and teeth . of type in the latter to great view of this skull (Fig. 35), after a section of the cal-varium has been removed, shows its most interesting feat-ures. Skulls of such extreme thickness, even among negroes. 142 ETIOLOGY OF OSSEOUS DEFORMITIES OF are rarely met with. The consistency of the bone in thiscranium is very dense and hard, and traditionally this negro,while alive, was noted for his butting propensities. Violentcontact with such a skull would be apt to damage the fist ofa Sullivan. Indeed, it is said that this fellow rather enjoyedthe impact of a policemans club. We will state at this point that we are of the opinionthat the massiveness of bony development in this case is notdue to disease. The general character of the overgrowth,and the consistency of the bone, would seem to support thisview. Syphilis may produce thickening of the cranial bones,as some of Virchows specimens show, but syphilitic bonedoes not present the characters and uniformity present in Fig. 36. At the densest part of the calvarium this specimenmeasured 13 mm. in thickness, its average thickness being11 mm. A comparison with Fig. 38 readily shows how phe-nomenal the osseous development in this case is. Thecranial measurements are:Horizontal index, . . Circumference, - - - - Anterior demi-circumference, -Longitudinal diam., - - - - Transverse Vertical diam. (vertex to foramen magnum),Bi-frontal diam., - - - - c. c. mm. 95 mm. THE HEAD, FACE, JAWS AND TEETH 143 Bi-mastoid diam., - - - - 113 mm. Bi-zygomatic diam., - - - - 126 mm. Anterior border of foramen magnum to sup. occipital angle, - - - 117 mm. The upper jaw and alveolar process in this skull is welldeveloped, the only peculiarity being a low palatal vault. Figs. 36 and 37 show the skull of a once notorious mem-ber of the Chicago demi-monde. She was a very tallwoman
