Eeduced alkaline haematin gives two sharp absorption bands, similar to those of oxyhaemoglobin, but rather nearer the blue end of the spectrum (Fig. 20). A body similar to, if not identical with, reduced alkaline haematin, Juemochromogen, is formed when haemoglobin is warmed with caustic potash in a vessel from which all air has.
