The above analyses indicate the extreme range of composition,
and are arranged in the order of their iron contents instead of chronologically.
It is probable that the highest percentage of iron (72 per cent.)
found in the early development of the working, was obtained from
a sample in which crystals were abundant, while in the lowest one
