dence of defect is observed, the immigrant receives a chalk mark indicating the nature of the suspicious circumstance.
At the end of each line stands a second medical officer who does nothing but inspect eyes. He everts the eyelids of every person passing the line, looking for signs of trachoma, and also notes the presence of cataract, blindness, defective vision, acute conditions requiring hospital care and any other abnormalities. All cases which have been marked on the line are separated from the others and sent to the medical examining rooms for careful examination and diagnosis.
