The red colouring matter of the blood. It resides in distinct particles or globules, and, in the opinion of some observers, in the envelope of the globules. It appears to be of a peculiar character, and one that has not yet been determined by the chemist. That the colour of the blood is not owing to the peroxide of iron which it contains is shown by the fact mentioned by Scherer, that he removed the iron by acids, and yet a deep red tincture was formed when alcohol was added to the residuum.
