PSEUDO-TELEPATHY 131

EXAMPLE 6

For this example, a person is asked to choose a number of
five or more digits. He is then to add the digits and to deduct
this sum from the original number. In the number which
results he is to cross out one of the digits other than a nought
and, having done this, to add the remaining digits together
and to disclose the result. If this result consists of more than
one digit the procedure for the extraction of digital roots (as
explained in Chapter 4) must be followed until the final root
has only one digit. This digital root is then deducted from g
and the balance will be equivalent to the digit crossed out.
The performer is therefore able to ‘divine’ the digit which
was crossed out even though he does not know the original
number selected.

If, for instance, the number originally selected is 12345,
the sum of the digits is 15. If this digital sum is deducted from
the original we have 12345 —15=12330; and if the digit g is
crossed out, the remaining digits total 6. This total, deducted
from g, gives the digit which was crossed out, 3.

The reason for this is that if we deduct from any number
the sum of its digits the result is always a multiple of g, so
that the digital root of the result is also g.

The elimination of any digit in the result therefore reduces
the digital root by an equivalent amount to the digit crossed
out.

The effect of this manceuvre may be made more mystify-
ing if the person who selects the number is not also asked to
add up the remaining digits. If he is told to read out these
digits, instead of their sum, the performer may add them
mentally and proceed as before.

The foregoing examples are all similar in that they do
not require any equipment for their performance. Selected
numbers may also be discovered by the use of specially pre-
pared cards, each card bearing certain sets of numbers. In
the example shown on the next page there are six sets of
numbers.
