The position of the images depends on the direction of the displacement of the affected eye; if this he in- wards or outwards, the object seen with that eye will be placed at the side of that which is seen in its proper position by the unaffected eye, and its distance from it will depend on the degree of the distortion and the distance of the object from the eye; if slight, the images will he near together; if more considerable, they will be further apart, and where the inversion or eversion of the eye is great, they will he so * This statement of course has reference to binocular diplopia, and not to that rare affection uniocular diplopia.
