This is occasionally impressed on one by discrepancies between the position of an object as determined by the eyes and that determined by tactile-proprioceptive sensation or objectively determined position. This discrepancy appears in cases of recent or fresh paralysis of the extra-ocular muscles which causes binocular diplopia. Immediately after the paralysis there is confusion because of the discrepancy, followed by gradual readjustment as the subject learns to disregard the falsely localized image. The objective interpretation of the relative positions of the double images in such cases, based on the simple laws of monocular projection, is well known, but analysis of
