sensitive structures, and showed no signs of discomfort even when I brought the candle-flame to within a couple of inches of his eyes.
But this extraordinary tolerance of light was easily explained by closer examination; for the pupils were contracted to such an extreme degree that only the very minutest point of black was visible at the center of the grey iris. Nor was this the only abnormal peculiarity of the sick man's eyes. As he lay on his back, the right iris sagged down slightly towards its center, showing a distinctly concave surface; and, when I contrived to produce a slight but quick movement of the eyeball, a perceptible undulatory movement could be detected. The patient had, in fact, what is known as a tremulous iris, a condition that is seen in cases where the crystalline lens has been extracted for the cure of cataract, or where it has become accidentally displaced, leaving the iris unsupported. In the present case, the complete condition of the iris made it clear that the ordinary extraction operation had not been performed, nor was I able, on the closest inspection with the aid of my lens, to find any trace of the less common "needle operation."
