s in dedit; both in
the third line, they cover the u's in tumus; both in the fourth, they
cover the n's in nemon.

If one be in the first line and the other in the second, they cover the
i's in cicos and dedit, and thus of the rest--the two cards thought
of NECESSARILY covering two SIMILAR LETTERS, whilst each of the letters
occurs only TWICE in the diagram.

7. To tell a card thought of without even looking at the cards.

Take any number of cards,--say twenty. Pretend to shuffle them with
the faces towards you, and REMEMBER THE FIRST CARD as you close
the pack--suppose the ten of diamonds. Tell the party that the only
condition you require is to be told the ORDER in which the card is dealt
out by you; in other words, he must tell you whether in dealing it comes
out first, second, third, &c.

Remembering your first card, you may then turn your back to him, and
deal out the cards one by one, and one upon the top of the other,
requesting him to think of a card and its order as before said.

Then take up the cards, and shuffle them repeatedly, by throwing a
portion of them from the bottom to the top, taking care not to mix the
cards or let any drop, and then let the party cut them as often as
he pleases. Then, take the cards in hand. Pretend to examine them
mysteriously, but in reality only look for YOUR card--the first dealt
out--the ten of diamonds for instance. Now, suppose he tells you that
the card he thought of came out FIFTH. Then, for a certainty, it is the
fourth card on the RIGHT of the ten of diamonds, in spite of all YOUR
shuffling, and all regular cutting, for such shuffling and regular
cutting cannot alter the order or sequence of the cards. Always remember
to count from your own card inclusive to the number of the card thought
of towards your right hand. But should your card happen to be so near
the right hand or the top as not to allow sufficient counting, then
count as far as it admits to the RIGHT and then continue at the LEFT.
Thus, suppose there are only two cards above the ten of diamonds, then
count two more on the left, making the fifth. If the card you remember,
or your first card, is first, then count the requisite number on the
left, always beginning with YOUR card, however.

The REASON of this trick is simply that by merely cutting the cards, and
shuffling them in the way indicated, you do not alter the SEQUENCE of
the cards. With regard to this sort of SHUFFLING, I may say that it
is simp
