BOARD FOR STRETCHING THE MUSCLES, ESPECIALLY THOSE OF THE THUMB AND THE
LITTLE FINGER.
Take a board, about 22 inches long, four to five inches wide, and three
quarters of an inch thick, and mark out on it four or five grooves,
about half an inch deep. To fix this board on the table, have a little
ledge glued on to one of its sides, as in Fig. 36 and 37.
Place the outstretched hand on the board; stretch the thumb and the
little finger as far as possible away from one another, into one of the
grooves, place the other fingers into one of the other grooves, and set
them in motion, while holding the thumb and little finger firmly in
their places.
