To Tell The Number Of The Cards By Their Weight
Take a parcel of cards, suppose forty, among which insert two long
cards; let the first be, for example, the fifteenth, and the other the
twenty-sixth from the top. Seem to shuffle the cards, and then cutting
them at the first long card, poise those you have cut off in your left
hand, and say, "There should be here fifteen cards." Cut them again at
the second long card, and say, "There are here only eleven cards."
Then poising the remainder, you say, "Here are fourteen cards."
