Siiperjicialis linguce.—An indis- tinct layer of muscular fibres on the dorsum of the tongue under the mucous membrane. \t seems to curl the tip upwards. Transversaks lingiia}^ — Are scattered fibres which pass from the middle line to the edge of the tongue ; they extend from the tip to the root, and their contractions lengthen the tongue. Verticales linguce.—These are fibres which extend from the up- per to the lower surface of the tongue. THE PALATE. The palate separates the back portion of the nose from the mouth, and is divided into two parts : the hard palaie consists of the palate processes of the superior maxillary and palate bones, covered by mucous membrane, which is continuous with that of the mouth, but is not so vascular or sensitive as that of other parts. It very frequently presents transverse ridges, as well as a ridge in the median line. The soft palate is the membranous separation between the back portion of the mouth and nose, and consists of a fold of mucous membrane stretched transversely. From its middle there projects the uvula^ about three quarters of an inch in length; from each side of the uvula there are two divergent crescentic folds of mucous membrane, which are called lateral half-arches ; the space between which constitutes the fauces. Between the anterior and posterior arches of each side is the Wnsil gland. The tonsil is about t
