    being formed into arches by this central appendage, is found almost straight. The Soft Palate, velum pendulum palati, or palatum molle, is described as a movable and fleshy curtain, ex- tending from the back of the palatine arch into the pharynx, of nearly a quadrangular figure, with an anterior and posterior surface, and four margins ; one superior, one inferior, and two lateral: the anterior surface concave, presenting downwards and forwards, and studded with numerous mucous ducts; the posterior surface, directed upwards and backwards, and elevated at its sides. At the lateral margins of the soft palate commence the musevdar folds, which constitute the palato-glossus and palato- pharyngeus muscles. The superior margin is attached to the posterior edge of the ossa palati, and the inferior hangs loosely into the pharynx formed into arches by the pen- dulous uvula which arises from its centre. The arches, velum palati, and uvula, are chiefly com- posed of muscular fibres, covered by mucous membrane, which is everywhere studded with follicles; the dorsum of the tongue also, at its posterior part, is furnished with numerous mucous glands, which give it the rough and tuberculated appearance it presents on looking into the mouth. The muscles of the soft palate are—the levator palati, the circumflexus palati, and azygos uvulce. The palato- glossus, passing down from the uvula to the side of the tongue, and constituting the anterior arch, assists above in forming the soft palate. In like manner, the palato-pha- ryngeus, passing from the uvula to the side of the pharynx, also contributes above to form the soft palate. These two last-mentioned muscles embrace the tonsil between them in the irregular triangular space or sulcus, in the manner
