Ventriloquism. The main secret of ventriloquism simply consists in first making a strong and deep inspiration, by which a considerable quantity of air is introduced into the lungs, to be afterwards acted upon by the flexible powers of the larynx, or cavity situated behind the tongue and the windpipe; thus prepared, the expiration should be slow and gradual. Any person, by practice, can, therefore, obtain more or less expertness in this exercise, in which, though not apparently, the voice is still modified by the mouth and tongue ; and it is in the concealment of this aid that much of the perfection of ventriloquism lies.
