Excerpt from Color-Vision and Color-Blindness: A Practical Manual for Railroad Surgeons The dangers of defective Form and Color-sense in railway employés have been set forth so convincingly by the medical profession, both individually and by resolu tions of representative medical bodies, that to-day practically every railroad company in the country re quires employés to be examined as to their color-sense, vision and hearing.
