TO SEPARATE A CHOSEN CARD FROM THE PACK AT A BLOW.

If the pack is placed between the finger and thumb of one of the company, holding it by one corner, and you strike them abruptly upwards with your wand while the grasp is tight, the cards will fly away, except the uppermost one. This will be caught between the fingers, on their coming naturally together on closing the pack between them.

Variation.—If the blow is given downwards the bottom card will be similarly retained.

It follows that if you have placed a selected card in either of the above positions described, it must be the one which is thus left in the person’s hold.
