The process of securing a record is as follows: the subject, standing, places his hand upon the automatograph, with the arm nearly horizontal and not quite fully extended, and the elbow bent in a fairly comfortable posture; his attention is engaged by asking him to listen to and count the strokes of a metronome; to look at and count the oscillations of a pendulum; to read from a book; to call out the names of colors; to think of a given direction or locality, or the position of an object; and so on. He is instructed to think as little as possible of his hand, making a reasonable effort to keep it from moving. To cut off the apparatus from the subject's field of vision and attention, a large screen is interposed between him and the record, a curtain with a suitable opening for the arm forming part of the screen. The operator holds the glass pencil in his hand, and when all is in readiness allows it to slip through the glass tube and begin to write, removing it again after a definite interval or when the record seems completed.

The arrows are used to indicate the direction in which the object attended to was situated, and also the direction in which the subject was facing. The tracings are permanently fixed by coating them with a weak solution of shellac in alcohol.]
