    Chap.vi.] The Nose. Si maxillary and internal carotid, the petrosal of the middle meningeal, and the stylomastoid of the posterior auricu- lar. The fact that some of the tympanic veins end in the superior petrosal and lateral sinuses gives another explanation of the frequent occurrence of thromboses of those channels in inflammatory affections of the middle ear. The petrosquamous vein, which crosses the roof of the middle ear, also receives branches from the antrum and attic and joins the lateral sinus behind and the meningeal veins in front (Cheatle). The connection between deafness and tinnitus aurium and affections of the stomach has to be sought for in the central connections of the eighth and tenth nerves. The blood supply of the labyrinth is derived entirely from the vertebral artery (Woakes). The chorda tympani nerve, from its exposed position in the tympanum, is very likely to be damaged in suppurative disease of the middle ear ; and Urban- tschitsch and Schulte have shown that such disease in this part may be associated with anomalies of taste. The osseous labyrinf li is formed independently of the other bony parts of the ear. Portions of this labyrinth have necrosed and have been expelled in recognisable fragments. In a case recorded by Dr. Barr the whole of the osseous labyrinth (the cochlea, vestibule, and semicircular canals) was removed entire as a necrosed fragment from the auditorv meatus. CHAPTER VI. THE NOSE AND NASAL CAVITIES. 1. The nose.—The skin over the root, and the greater part of the dorsum, of the nose, is thin and lax. Over the ake, however, it is thick, very adherent to the deeper parts, and plentifully supplied with sebaceous and sweet glands. Inflammation of the integuments over the cartilaginous portion of the nose is apt to be very painful, and to be associated with much vascular
