  HEATH'S MICROSCOPE
  

  Item 105 in George Frederick Kolbe's 2003 Numismatic
  Bookseller fixed price list is an unusual piece related to the
  famous Heath's counterfeit detectors. "Heath's Improved
  Adjustable Compound Microscope, [Patented Dec 25,
  1877]. For Examining Bank Notes, Minerals, Flowers,
  Seeds, Linen, Etc., Etc." The device was illustrated in
  late editions of Heath's counterfeit detector. George lists
  it as "The first we have seen." It's the first I've even heard
  of these - time to go check my later Heath editions.
