Stain with carbol fuchsin and heat until boiling. Allow to cool, 
wash in distilled water, decolorize either with Gabbet’s methylene 
blue and sulphuric acid or with 20 per cent aqueous nitric or 
sulphuric acid, and counterstain with Leeffler’s blue. Personally 
I do not like a counterstain, but this is a matter of little 
importance.
