A person may see as f ar with one perfect eye as with two, but he cannot see as clearly; for the advantage that binocular, or doublé, visión possesses over monocular, or one-eyed, visión is that the former, by allowinfj the observer to catch sight of the object from two different points of view, gives hira at once some idea oí the proportions of it3 different parts. Bnt though this is true in theory, in practice the judgmentinterferes, and the judgment has been educated and in some measure rendered independent oí the services of binocular visión by experience and the use of other senses, such as touch, says the Washington Post. Thus a man with only one eye is never deceived as to the nature of an object with which he is well acquainted, for the report of it that he gets írom his visión is corrected and supplemented by his experienced judgment and transmitted to his centers of consciousness iu as perfect a form as that which reaches those of a man with two eyes. The advantage of binocular visión may be thus further illustrated: ín rapidly dipping a pen into an inkstand or putting a stopper into a decanter the one-eyed man cannot judge so accurately as the two-eyed man. Or, again, if we shut one eye and attempt to plunge the finger rapidly into the open mouth of a bottle we are apt to overreach. or fall short of it.
