    membrane of the tympanum, it is inseparably united with the periosteum and perichondrium over which it lies (Quain). The mucous membrane of the nasal cavities is divisible into two parts, viz.:—(1) That of the olfactory region, which occupies the superior and middle tur- binated bones, and the upper part of the septum, and (2) that of the non-olfactory or respiratory region, which lines the remainder of the cavity, and is commonly known as the Schneiderian or pituitary membrane. (1) In the olfactory region (olfactory places/' Klein) the mucous membrane contains the ramifications of the olfactory nerve, and is the seat of the organ of smell. In a practical work of this description it is not neces- sary to describe the minute anatomy of this mucous membrane. It will suffice to state that it is provided with pig- ment which gives it a brownish or yellowish hue, and is covered by non-ciliated cylindrical epithelium. According to Klein, not the whole of the olfactory region as usually described is covered with olfactory mucous membrane, but in many places we find smaller olfactory portions alternating with those of a non-olfac- tory character. (2) In the non-olfactory or respiratory region, the nasal mucous membrane varies much in thickness in different parts. On the septum, and especially over the margins and extremities of the conchas it is very thick, whilst in the intervals between the turbinated bones, and on the floor, it has a much thinner character. For practical reasons it is necessary to describe its structure more in detail. It is covered with columnar ciliated epithelium, similar to that of the larynx and trachea, containiug
