Abstract
The lectometer is a special form of tachistoscope which provides a connection with a chronoscope. Through an open, adjustable sector of a rotating disc is presented material for reading. Just as the view is shut off a small arm attached to the spindle of the disc dips into mercury, thus completing an electric circuit which sets the chronoscope into action. The observer reads into a voice key which stops the chronoscope and gives the time to the thousandth of a second it takes him to know and say what he had observed during the short view.
