Expected results


  1. Gray states that this solution is, "an excellent general purpose hematoxylin".
  2. The stability of the solution is not commented on, but it is likely not stable for long.
  3. This method is from a technique for micro-organisms, so the staining time may need to be adjusted for sections.
