EXERCISE 4.

[Illustration]

Lay the left hand flat palm down on a table, book, or other smooth

surface. Open the thumb out of the way of the fingers.

Grasp the index finger of the left hand with the thumb and finger of the

right hand. Allowing the finger to move freely, draw it along the

surface as far as possible without straining the muscles. Do this five

times. Now with the finger muscles resist the movement, and repeat the

exercise five times more.

Allowing the finger to move freely once more, lift it from the table in

a large semi-circle, and swing it over towards the thumb and down to the

table again. Repeat five times.

Go through this same movement five times with muscle resistance.

Carry out these exercises on the other fingers of the left hand, and

then on all of the fingers of the right hand.
