AD., Capivacci described a method of differentiaing
between the deafness produced by the peripheral or central
type of lesion. One end of the iron rod was put between
teeth of the patient while its other end was placed
upon a keyed musical instrument. If the patient can
distinguish between the tones produced by the vibrations
of key of the instrument, his deafness was due to some
disease in tympanic membrane, if not it was an affection
of the nerve. |

the ear of thieves. He said, such treatment rendered
them incapable of propagating their kind and hence no

rendered a man sterile, because the semen which was
generated in the brain could no longer pass down to
the genitals.
