title: Unequal retinal illuminance and the binoculus.
abstract: An investigation was carried out in the relationship between the position of the binoculus and the depth (transmittance) of a monocular filter. The method used relied on changes in motor function and the linearity of the relationship found by previous workers, who used purely visual techniques, was confirmed. Some anomalous results were found which remain unexplained.
