EXERCISE 28.
Lay your right hand, palm down, flat on any plane surface. Press the fingers quite firmly down on the table. Place the forefinger of the left hand on the nail of the forefinger on the right hand with a slight amount of pressure. Raise the forefinger of the right hand as high as possible from the table against this pressure. Keep the forefinger of the right hand straight, save at the knuckle joint, and the other fingers firmly on the table. Return the finger to the table against muscular resistance. Repeat this exercise twenty times.
Go through this same exercise with the other fingers of the right hand, then reverse and proceed with the fingers of the left hand.
Do this exercise with the thumb nail, but instead of having the whole hand flat on the table, have the fingers curl, so that the side of the hand touches the table, and raise the thumb against the pressure of the finger of the opposite hand twenty times.
