Jackson's Gymnastics for the Fingers and Wrist / being a system of gymnastics, based on anatomical principles, for developing and strengthening the muscles of the hand for musical, mechanical and medical purposes: with thirty-seven diagrams

by Edwin Ward Jackson

Hold the fingers close together, stretch out the thumb, and then perform with the latter a circular movement inside the hand, first 20 times to the right, then 20 times to the left: to be repeated again and again.

Third movement.

Fig. 16.

Take hold of the thumb of the one hand with the fingers of the other, or with the whole hand, and shake it or bend it to its root, without, however, overdoing either.

In short, perform every day some exercise with the thumb, whereby it will be sufficiently brought into exercise.
