Degeneracy: Its Causes, Signs and Results

Abnormalities, Human; Degeneration; Heredity, Human
shaped, and its proper proportion and size may be inferred from the table
just given; in the adult it should not average over two and a half inches
in length and one and a quarter in breadth.
The aural deformities that fall under the head of stigmata, or have been
classed as such, affect all portions of the external ear. The helix may be
imperfect, it may be angular, from Darwin's tubercle it may lack its
inward roll, it may be interrupted, the root of the helix may extend
inward completely across the concha, and in very rare instances it may be
bifurcated. The anti-helix may be unduly prominent or be insignificant;
the scaphoid fossa may extend through the lobule or be triple.[213] The
lobule may be adherent and sometimes almost absent, thus producing the
jug-handle-shaped, or so-called Morel ear. It may be exaggerated in size;
the whole ear may be misshapen, too large or too small. These deformities
may exist in nearly every degree, only when pronounced can they be
considered as stigmata. Others have been noted, but their importance as
signs of degeneracy is not very significant unless they co-exist with
several of those above mentioned.
[Illustration: FIG. 39.]
The ears of degenerates frequently grow in later life to an enormous size.
On examination of 207 paupers over 50 years old the shortest ear was found
to be 2·25 inches, the longest 3·36; the average on the right side was
2·73, on the left 2·76; the narrowest ear was ·88, the widest 1·50, the
average 1·26. These results, compared with the results of the measurements
of normal persons from 12 to 50 years, plainly demonstrate that the ears
of degenerates grow after the twenty-sixth year, when the skeleton has
completed its development. With such large ears other stigmata are
generally associated. A few of the best types of stigmata of the ear
illustrate better than any description the general characteristics. Fig.
39 illustrates the ear _par excellence_ of degeneracy, the typical
jug-handled ear first described by Morel and called by his name. This
consists of a long, narrow ear attached its entire length, and tapering
upward and outward from the lobe to the point where the Darwinian tubercle
is located, and there it may take any shape--round, straight, or
pointed--as illustrated in the drawing. The most singular deformity of the
helix is the tubercle of Darwin, which is a little blunt point,
projecting from the inwardly folded margin or helix. When present it is
developed at birth and, according to Ludwig Meyer, more frequent in men
than in women. Fig. 40 shows ear and tubercle taken from Darwin.[214]
These points not only project in toward the centre of the ear, but open a
little outwards (Fig. 41) from its plane, so as to be visible when the
head is viewed from directly in front and behind. They are variable in
size, number and somewhat in position (Fig. 42), standing either a little
higher or lower, and they sometimes occur on one ear and not on the other.
