Mayer (1896) and Langeron (1924) both published formulae with 4g hematoxylin
in conjunction with 50g alum in a litre of fluid, but they both used a
mixture of water and glycerol (700 to 300) as the solvent.  Langeron
specified 20 mL acetic acid, Mayer specified none.  Both omitted the
oxidiser.  The formula appears to be a blend of Langeron's 1924 formula with
his 1942 formula (what is usually meant when "Mayer's" hemalum is
specified).

If anyone can provide a reference I would like to put the formula on
StainsFile with all the rest.
see: http://netbistro.com/~bryand and select
        Staining methods, then
        Mordanted hematoxylin formulae, then
        Alum hematoxylin solutions
Check Mayer and Langeron in particular.
