It may be readily seen, that the pieces, instead of being in the two
hands of the same person, may be supposed to be in the hands of two
persons, one of whom has the even number, or piece of gold, and the
other the odd number, or piece of silver. The same operations may then
be performed in regard to these two persons, as are performed in regard
to the two hands of the same person, calling the one privately the
right and the other the left.
THE NUMBER BAG
The plan is to let a person select several numbers out of a bag, and
to tell him the number which shall exactly divide the sum of those he
has chosen; provide a small bag, divided into two parts, into one of
which put several tickets, numbered, 6, 9, 15, 36, 63, 120, 213, 309,
etc.; and in the other part put as many other tickets marked number
3 only. Draw a handful of tickets from the first part, and, after
showing them to the company, put them into the bag again, and, having
opened it a second time, desire any one to take out as many tickets
as he thinks proper; when he has done that, you open privately the
other part of the bag, and tell him to take out of it one ticket only.
