One who sees with one eye only always thinks he is nearer to the object than he really is when reaching out for that object. It is always more difficult for him to pour from a pitcher into a cup or glass if held a little distance below it, hence the blind in one eye usually place the nose of the pitcher in contact with the glass before pouring. The old parlor trick of placing two pins in the wall and putting a cent on them and directing the patient to stand across the room and then walk over to the cent and knock it off with the outstretched finger without hitting the pins, may be made use of as a test in simulated blindness, for with one eye the patient always falls short of the mark the first time the experiment is tried. The most simple method of detecting simulated blindness in one eye is by noticing the movement of the pupil under the influence of light. If an eye is blind, the light has little or no effect upon it when the other eye is closed. The pupil is usually dilated. It may be well to mention here that atropine dilatation is generally wider than that due to amaurosis, and also that a cone of light from a strong convex glass thrown upon the sound eye will contract the pupil of the blind eye if the dilatation is not due to atropine. Simulated blindness in both eyes is not likely to be seen, and then the condition of the pupil is of great value in detecting it, and is one of the best guides in connection with the ophthalmoscopic observation. A CASE OF DOUBLE UTERUS AND VAGINA. BY S. W. KELLEY, M. D., CLEVELAND, O. Miss H. E., aged 20, American of Irish parentage: dark brunette, short in stature but apparently quite handsomely formed, and ruddy with health. She has never been sick in her life. Has menstruated normally since her fifteenth year, though scantily during the past year. She feared she had been injured a few days previously by the overturning of a chair upon which she was standing, as she had since felt pain and uneasiness in the lower pelvic and pubic region, for which she sought advice. Upon examination I found no injury worthy of record, but the malformation here described. Cases of this anomaly have been recorded from time to time, being always of interest to the teratologist, occasionally requiring attention on account of interference with the marital relation or parturition, and being referred to in every discussion on superfœtation.
