Fig. 1. Sarcoma of Auricle (P.).

Fig. 2. Lupus Vulgaris of Auricle (P.).

Fig. 3. Carcinoma of Auricle and Temporal Bone (P.).-Left ear of a man forty-six years of age who had suffered from aural discharge. The carcinoma extended into the body of the temporal bone.

Fig. 4. Acquired Stricture of External Auditory Meatus (B.).—Left ear of a man who had been run over by a wagon in early childhood. Immediately behind the opening of the auditory meatus there is a connective-tissue septum stretched across the canal like a diaphragm, with a round opening that admits a sound the size of a pin-head. He can hear whispered conversation at a distance of three meters.

Fig. 5. Othematoma of Auricle (B.).—The tumor developed without any ascertainable cause in the fossa triangularis of a man twenty-three years of age.

Fig. 6. Spontaneous Cure of an Othematoma (B.).-Ear of a man thirty-six years of age afflicted with paralytic dementia, who had had an othematoma several years before. The triangular fossa and the antihelix are disfigured by atrophy of the cartilage and cicatricial contraction.

Fig. 2. Cyst of Left Auricle, Growing from Posterior Surface (P.).

Fig. 3. The So-called Darwinian (Darwin-Woolner) Ear; Acquired Coloboma of the Lobe of the Ear (B.).-Right ear of a woman sixty years of age suffering from paralytic dementia. 1, Darwinian point (true point of the ear); 2, laceration of the lobe by wearing ear-rings.

Fig. 4. Wildermuth's Ear; Adherent Lobe; Auricular Appendages (B.). Right ear of an alcoholic subject forty years of age: 1, Antihelix projecting well beyond the helix; 2, the lobe is adherent and extends to the cheek; 3, auricular appendages (added from the ear of another subject).

Fig. 5. Cercopithecus Ear: Combination of Satyr and Darwinian Point; Congenital Fistula Auris (B.).-Right ear of a man fifty years of age suffering from paralytic dementia: 1, Satyr point; 2, Darwinian point; 3, congenital fistula auris (added from the ear of the other side).

Fig. 6. Microtia, with Congenital Atresia Auris (B.).-Male, thirtyseven years of age. The right ear is deformed; the left, a cat ear. Arrested development of the right side of the skull. Impaired mobility of the right half of the palate. Deviation of the nasal septum to the right. When the left ear is held shut, the patient can hear low-pitched, but not high-pitched, whispered words at a distance of five centimeters. Tuning-forks C, c, cl, c2, when placed on vertex, heard in the right ear. Air-conduction absent; bone-conduction good. The Galton whistle is heard at the mark 4 (normal 2). Instead of an auricle, the subject possessed a long fold of skin containing a plate of cartilage extending to the lower portion (lobe) (1). Above, the cartilage contains a short, blind canal-adhesion of descending and ascending helix (2); below the middle the cartilage contains a tubercle (3) (union of middle portion of helix with tragus); behind the latter there is a blind depression (rudimentary auditory meatus).
