The first things which disappear in dark Bodies, when removed from the Eye, are their Terms or Contours; at a little further distance, the Shadows, which divide the parts of contiguous Bodies, cease to be seen; further yet, the thickness of the Legs, and Feet begin to dwindle; and lastly, the smallest parts disappear, by little and little; till at length, the Object being removed to a great distance, appears no other than a dim confused Mass, without any thing distinct in its Figure or Parts.
