(2) The scutiform cartilage ([p. 418]) should be observed in the natural position, and as isolated.
(3) The muscles of the external ear ([p. 418], and [Fig. 169]). Those connecting the external ear with other parts of the head have been studied in connection with the facial muscles. The remainder will be studied on an external ear removed according to the directions given on [page 435].
Remove the integument from the convex surface of the auricle, sufficiently to expose the entire extent of the muscles.
1. The rotator auris. Transect.
2. The adductor auris superior ([Fig. 169], 1).
3. The adductor auris medius (2).
4. The transversus auriculæ ([Fig. 63], i, [p. 97]).
5. The auricularis externus ([Fig. 169], 10).
6. The helicis ([Fig. 169], 3). To expose this it will be necessary to remove the integument from along the cranial border of the inner surface of the auricle.
7. The antitragicus ([Fig. 169], 6). Remove the integument farther if necessary.
