IV. To file the card.— To file the
card is, when a card has been taken from the pack to pretend to
place it about the middle of the pack, whilst, in reality, you
place it at the bottom.
The pack must be held in the left hand, between the thumb
and forefinger, so that the three other fingers be free. One of
the middle cards should project a little. Then take the card to
be filed between the forefinger and the middle finger of the
right hand; advance the right hand from the left, and whilst the
three disengaged fingers of the left hand seize and place the
card under the pack, the thumb and forefinger of the right seize
the projecting card before mentioned, so that it seems to be that
card which you have slipped into the
middle of
the pack. These movements are shown
in fig. 4. They are very easy, and, when rapidly performed, the
illusion is complete.
