"The Boy Mechanic: Volume 1 700 Things for Boys to Do"

This is accomplished by simply turning the deck end for end
while the observer is looking at his card, thus bringing the wide
end of the selected card at the narrow end of the pack when it is
replaced. The hands are placed behind the pack for a double
purpose, as the feat then seems more marvelous and the observers
are not allowed to see how it is done.
In prize games, players having the same score are frequently
called upon to cut for low to determine which shall be the winner,
but a fairer way is to cut for high as a person familiar with the
trick shown in Fig. 2 can cut the cards at the ace, deuce, or
three spot, nearly every time, especially if the deck is a new
one. This is done by simply pressing on the top of the deck as
shown, before cutting, thus causing the increased ink surface of
the high cards to adhere to the adjacent ones. A little practice
will soon enable one to cut low nearly every time, but the cards
must be grasped lightly and the experiment should be performed
with a new deck to obtain successful results.

** A Constant-Pressure Hydrogen Generator [70]
By fitting three bottles, A, B, C, with rubber stoppers and
connecting with glass tubes as shown in the sketch, hydrogen or
other gases produced in a similar manner may be generated under
constant pressure.
