Such facts as these have stimulated experiment in the direction of testing thought transference. These experiments have usually been in the reading of numbers and names, and a certain measure of success has resulted.

Persons in hypnotic trance are expert muscle readers. For instance, let such a person take your hand and then go through the alphabet, naming the letters. If you have any word in your mind, as the muscle reader comes to each letter the muscles will unconsciously contract. By giving attention the muscles you can make them contract on the wrong letters and entirely mislead such a person.
