1 QUALIFIER:

  Qualifier Code: TaxaNote
  Description: Notes taken about the taxa for a count; older data typically includes information such as beginning and end scan coordinates, unusual taxa, etc.
  Comments: Row 1 x 40, y 85; y 102 It took me over an hour to reach a count of 121 valves. This happened because there are many broken pieces and it takes longer to identify them. There are also intact valves and frustules, so the broken pieces are not generated during prepartion. Therefore, it would take longer that four hours to reach a count of 600 valves.
