He took a common sewing needle of medium size (length 1 5/8 inches) and drilled a hole through its entire length from eye to point--the opening being just large enough to admit the passage of a very fine hair.

Another workman in a watch-factory of the United States drilled a hole through a hair of his beard and ran a fiber of silk through it.
Ventriloquists, or "two-voiced men," are interesting anomalies of the present day; it is common to see a person who possesses the power of speaking with a voice apparently from the epigastrium.

Some acquire this faculty, while with others it is due to a natural resonance, formed, according to Dupont, in the space between the third and fourth ribs and their cartilaginous union and the middle of the first portion of the sternum.

Examination of many of these cases proves that the vibration is greatest here.

It is certain that ventriloquists have existed for many centuries.
