An Easy Method of obtaining Methaemoglobin Crystals for Microscopic Examination
W. D. Halliburton- Cell Biology
ABSTRACT
Methæmoglobin is a derivative of the red colouring matter of the blood, concerning which a number of theories have been held. According to Sorby,1 it is more highly oxygenated than oxyhaemoglobin; that is, it is a per-oxyhæmoglobin. Hoppe-Seyler,3 on the other hand, regards it as a sub-oxyhæmoglobin, as it can be obtained under conditions which remove at least part of the oxygen of oxyhaemoglobin. According to both these views, however, the oxygen is regarded as being more firmly combined with the haemoglobin than in the case of oxyhæmoglobin.
