Microscope

Description
This is a small magnifying glass in a metal frame that, according to the text on its cardboard box, was designed “For examining bank notes, minerals, flowers, seeds, linen, etc., etc.” It was designed and sold by Laban Heath (1837-1894), a New England engraver who specialized in detecting counterfeit currency. This was collected by Richard Halsted Ward (1837-1917), a noted medical microscopist, or his son, Henry B. Ward, a pioneering parasitologist.
