Here is a revised version.
>Acid amidol
Water (boiled to get rid of dissolved oxygen) 568 g
Sodium sulphite crystals. 42g
Sodium bisulphite 36 ml
Amidol
4 g
Potassium bromide O. 5g.
(a small pinch)
Add 14 ml of sulphuric acid to 200 ml of water then add 115g of sodium
sulphite ( crystals ) and shake until dissolved.
The recipe comes from the 14th edition of the Illiffe Dictionary of
Photography from around 1936. I assume that the first edition, the format
is the same, was that edited by Walter Woodbury in 1890. It was the
first dictionary that I read from cover to cver.
