PLATE 16.













1. Fibrous Tumor (Keloid) of Right Auricle (P).













2. Cyst of the Left Auricle, Growing form the Posterior Surface (P.).













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













4. Wildermuth's ear; Adherent Lobe; Auricular Appendages (B.). -Right ear of an alcoholic subject forty years of age: 1,m 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).













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













6. Microtia, with Congenital Atresia Auris). -Male, thirty-seven years of age. The right ear is deformed; the left ear 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 right 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, c', c2, when placed on the 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).
