    tition, for in this way the sense of smell is suspended in great measure, and the ordinary flavor of many kinds of solid food, such as freshly cooked meats, becomes almost imperceptible. A very similar effect, as already remarked, is, at times, produced by an acute or chronic catarrhal inflammation of the nasal pas- sages, which suspends more or less completely the sensibility of the olfactory membrane. * • Eepeated inflammations of the pituitary membrane lead too frequently, by propagation, to diseases Avhich at first do not appear to have close relationship with them. Amongst the most important of these are chronic affections of the middle ear, the laryngeal sac, and the maxillary, frontal, and sphenoidal sinuses. The pituitary membrane is rich in acinous glands, which, normally, exude a small amount of mucous secretion, thus moistening the surface. According to Cohen, f this moisture is more probably due to the deposit of water from the expired breath. Be that as it may, it is certainly true that a perfect physiology, which says a man ought never to blow his nose to get I'id of an excess of secretion from the nasal passages, loses sight of the fact that, in our climate, an individual would thus become very uncomfortable and jDarched in breathing. Extreme vascularity of the pituitary membrane explains the unusual frequency of epistaxes, which occur in catarrhal inflam- mations of the nose, and the special venous distribution over the inferior turbinated bones accounts clearly for the march of ordinary coryza. The nerves of the pituitary membrane are of two orders: 1st, a nerve of special function, the olfactory. The terminal filaments of this nerve do not extend beyond the middle meatus, or the middle turbinated bone, giving a particular character to the * Dalton, Human Physiology.
