Images of graphite have been recorded with a scanning tumneling microscope operating in air at ambient pressure. The results, which are in agreement with theory and 
previous experiments in vacuum, confirm that with a surface such as graphite the tunneling microscopy in air can be used to examine the geometry of the surface with a 
resolution that is less than 2 A.
