Partly subdivided by a curved ridge, the vestibule is lined with skin and, in its lower half, there are hairs and sebaceous glands; the hairs are curved downwards to guard the entrance to the nostril. The superior part of the vestibule is smooth, and is limited above and posteriorly by a slightly marked arched prominence, the limen nasi, beyond which the nasal cavity is lined with mucous membrane. Each nasal cavity, above and behind the vestibule, is divided into a superior or olfactory, and an inferior or respiratory region. The olfactory region is a narrow slit-like space, and comprises the middle of the superior nasal concha and the corresponding portion of the septum. The respiratory region includes the remaining part of the cavity. Septum Nasi (Fig- 668).—Where the bony septum of the nose is deficient, below and in front, the gap is filled by the septal cartilage. Until the seventh year the nasal septum lies, as a rule, in the median plane, but after this age it is very often bent to one or other side—more frequently to the right—the deflection being greatest usually along the line of junction of the vomer with the perpendicular lamina of the ethmoid. De- flection of the septum is more common in Euro- pean than in non- European skulls — occurring in about 53 per cent of the former and in about 28 per cent of the latter (Zuckerkandl). Associated with, or apart from, this deviation, crests or spurs of bone are found,project- ing from th
