Thus the bones of a young pigeon were tinged of a rose colour in twenty-four hours, and of a deep scarlet in three days ; while in the adult bird, fifteen days were required merely to produce the rose colour. The dye was more intense in the solid parts of those bones which were nearest to the centre of circulation, while in bones of equal solidity, but more remote from the heart, the tinge was fainter. The bone was of a deeper...
