In front the lower lateral cartilages are separated by a notch which corresponds with the point of the nose. The cartilage of the septum (carfilago septi nasi) (Figs. 794 and 796) is somewhat quadrilateral in form, thicker at its margins than at its centre, and completes the sepa- ration between the nasal fossa in front. Its anterior margin, thickest above, is connected with the nasal bones, and is continuous with the anterior margins of the two upper lateral cartilages. Below, it is connected to the inner portions of the lower lateral cartilages by fibrous tissue. Its posterior margin is connected with the perpendicular lamella of the ethmoid; its inferior margin with the vomer and the palate processes of the max- illa? (Fig. 796). It may be prolonged backward (especially In children) for some distance between the vomer and perpendicular plate of the eth- moid, forming what is termed the sphenoidal process (processus sphenoidalis septi cartila- ginei). The septal cartilage does not reach as far as the lower part of the nasal septum. This formed by the thinnest portions of the lower lateral cartilages and by the skin; it is freely movable, and hence is termed the mobile septum. Along the lower margin of the anterior half of the cartilage of the septum is another cartilage which is attached to the vomer and
