On the anatomy of vertebrates [electronic resource] . fig. 159, b, is bent uponitself, almost surrounding and go-verning the shape of the nostril:it is movably connected with thelower and outer part of a. To theouter and hinder apex of the carti-lage b, is joined the first of the threesmall cartilages, c, d, e, which sup-port the posterior convex part of the6 ala or wing of the nose. The flex-ible fibrous tissue connecting theseelastic cartilages allow of the move-ments of the parts to be readily pro-duced, and the muscles are accord-ingly feeble. The e pyramidalis nasi,fig. 161, c, is continued from themedial portion of the 6 frontalis, ,/, which descends over the upperpart of the nose to the cellular tis-sue covering the cartilage, a, and thence onward to combinewith fibres of the f triangularis nasi, fig. 161, e, and fig. 29, n. The levator labii superioris alaeque nasi is shown at dd, fig. 161 ; inthe degree in which the alar is distinct from the labial portion,or has been distinctly exercised, the wings of the nose can be ex-.

Thec depressor alae nasi/ ib. f9 arises from the outer border of thesockets of the canine and contiguous incisor: the fibres ascendto the alae, many of them arching over the outer and back pro-minence of the nostril. The 6 depressor septi, ib. k, is detachedfrom the upper part of the £ orbicularis oris, fig. 29, oo, thefibres converging from each side toward the nasal septum. Thesmall triangular patch of pale fibres, fig. 161, g, is the i com-pressor narium minor: the larger quadrilateral muscle, h, is thes levator alae proprius. In races, like the Mincopies of theAndaman Islands 1 who scent the ripeness of indigenous fruits,moving the thick alae of their squab nose, as they explore theirdark forests for this purpose, the nasal muscles may be expectedto be well and instructively developed. § 216.
