Abstract
There are too many types in the human earform to make approach to the study of heredity and if some characteristics of the ear are taken up one by one, we shall fail to have a whole picture of earform. So it will be reasonable to classify them into some groups of the characteristics which correlate with one another.
Writer recorded nineteen characteristics in the ear by making reference to the hook of BONEWITZ, H, (1934, Eine Studies zur Morphologie and Vererbung einzelner Merkmal der menschlichen Ohrmuschel), and tested the correlation between them. Nineteen characteristics are as follows:
a. inclination of the ear against the head b. congenital canal of the earlobe c. startiflg area of crus hilicis d. direction of crus helicis e. form of helix (frontal) f. form of helix (upper) g. form of helix (hinder) h. helix and upper ear attachment i. skapha j. tragusk. tragus accessorius 1. antitragus m. incisura intertragica (form) n. incisura intertragica (degree of formation) o. Lobulus (degree of formation) p. Lobulus (form) q. Lobulus (thickness) r. form of the whole ear s. tuberculum auriculae (Uarwini)
By testing the correlation, these nineteen characteristics are classified into three groups and five independent characteristics. One group consists of c, e, f, g, i, m, n and r, another one of d, j and k, and the last of o and p. The independent characteristics are a, b, h, q and s.
