The external ear is now attached to the head only by the external auditory meatus and the tragicus lateralis muscle. Read the description of the latter ([p. 418], and [Fig. 67], a), find it beneath the fat which surrounds the proximal portion of the external ear, and cut it as far ventrad as possible. Now cut across the cartilaginous auditory meatus as near to the tympanic bone as possible, and remove the external ear, preserving it for future study. (The remainder of the muscles of the external ear may be studied in connection with the study of the auditory organ.)
