ation taking place from the right, the softtissues and the galea aponeurotica are recognised as a light shadow.The soft tissues of the nose, lips, and chin appear conspicuously. Of the bony parts, the external occipital protuberance, also theorbital, nasal, and sphenoid cavities are easily recognised. In thecentre of the temporal bone the light shadow of the external audi-tory canal is seen. Below the latter the small cavities of the mas-toid process may be perceived; the zygoma is also quite distinct.The nasal bones and the superior maxilla showing the quadrangu-lar shadow of the antrum of Highmore, can especially well be rep-resented. (Fig. 28.) The nasal process, the hard palate, the alveolar process, andits cells and teeth, the inferior maxilla, showing its mental fora-64 THE HEAD 65 men, the protuberance, the external oblique line, the angle with itstwo processes, can be well demonstrated. With these osseoue struc-tures the shadow of the tongue and the velum palati contrast well.

The motions of the velum palati and of the tongue can be easilystudied by the fluoroscope. Schneier has considerably increasedour knowledge on the physiology of the phonation by his fluoro-scopic studies in this connection.G 66 THE RONTGEN KAYS By placing the patients face on the plate, and the tube behindit, the margins of the orbit, the frontal and nasal cavities, and thenasal bones seem well outlined. Tumours of the facial bones are representable, while intra-cranial growths show under extraordinary circumstances only. Ifcontaining calcareous matter they appear marked, of course. In a girl of two years (Fig. 278) the connection of gliomawith the orbital wall as well as the proliferation into the opticforamen could be proved by skiagraphy. Thus the technical diffi-culties of the operation wereillustrated beforehand, whichis important in a case theprognosis of which is so ex-tremely grave.
