    the part of a swing-door or gate, closes the nares during deglutition, but immediately afterwards re- sumes its usual position, where, hanging like a loose curtain from the hard palate, and therefore appro- priately named velum penduhtm palati, it separates the mouth from the throat more or less completely, according to the constantly varying degree to which it descends or is drawn up. The loose border of the velum is so shaped as to make it resemble a scolloped valance or looped-up cur- tain ; for this free edge in its course from one side to the other describes two arcs, separated from each other by a conical prolongation, which descending between the two is common to both, and is named the uvula. The two concave or retracted segments are called the arches of the fauces. From these the outer bounding folds are continued downwards—one on each side-as low as the floor of the mouth, so as to form a pair of columns or piers from which the arches may be said to spring, and which are named the pillars of the fauces. Thus the uvula appears as one imperfect division between the two arches which communicate below. When the velum is completely retracted, the central part is drawn up so much higher than the sides, that the two concave segments seem thrown into each other, so that we have only a single arch spanning the distance from side to side, sup- ported on the two pillars, with the uvula looking like a mere ornament suspended from the keystone. -Exa- mining the parts a little more closely, we see that there is a second pair of columns, one standing in front of the other ; they are distinguished as the ante-
