vocal cords until the age of
twenty-three, thus establishing the voice. Poore also recorded a case
of congenital web in the larynx. Elsberg and Scheff mention occlusion
of the rima glottidis by a membrane.

Instances of duplication of the epiglottis attended with a species of
double voice possess great interest. French described a man of thirty,
by occupation a singer and contortionist, who became possessed of an
extra voice when he was sixteen. In high and falsetto tones he could
run the scale from A to F in an upper and lower range. The compass of
the low voice was so small that he could not reach the high notes of
any song with it, and in singing he only used it to break in on the
falsetto and produce a sensation. He was supposed to possess a double
epiglottis.

Roe describes a young lady who could whistle at will with the lower
part of her throat and without the aid of her lips. Laryngeal
examination showed that the fundamental tones were produced by
vibrations of the edges of the vocal cords, and the modifications were
effected by a minute adjustment of the ventricular bands, which
regulated the laryngeal opening above the cord, and pressing firmly
down closed the ventricle and acted as a damper preventing the
vibrations of the cords except in their middle third. Morgan in the
same journal mentions the case of a boy of nineteen, who seemed to be
affected with laryngeal catarrh, and who exhibited distinct
diphthongia. He was seen to have two glottic orifices with associate
bands. The treatment was directed to the catarrh and consequent paresis
of the posterior bands, and he soon lost his evidences of double voice.

{footnote} The following is a description of the laryngeal formation of
a singer who has recently acquired considerable notice by her ability
to sing notes of the highest tones and to display the greatest compass
of voice. It is extracted from a Cleveland, Ohio, newspaper: "She has
unusual development of the larynx, which enables her to throw into
vibration and with different degrees of rapidity the entire length of
the vocal cords or only a part thereof. But of greatest interest is her
remarkable control over the muscles which regulate the division and
modification of the resonant cavities, the laryngeal, pharyngeal, oral,
and nasal, and upon this depends the quality of her voice. The uvula is
bifurcated, and the two divisions sometimes act independently. The
epiglottis during the production of the
