And this hypothesis is entirely in harmony with the phenomena of allotropy.
This would be quite in accordance with the chemical notion of allotropy.
allotropy has turned the eyes of many back to the remoter past.
Thus carbon occurs as the diamond, and as charcoal and plumbago, and is therefore regarded as a substance subject to allotropy.
