Note 224 — Chapter IV · THE PROTO-CHALCITIC OR COPPER AGE OF WEAPONS.
Reading edition
It was analysed by Mr. E. Tookey, with the following results:
Copper 97·12
Arsenic 2·29
Iron 0·43
Tin, with traces of gold 0·24
100·08
The presence of the tin may have been accidental. The proportion of arsenic (2¼ per cent.) might have been expected to harden the metal, yet it was so soft as to be almost useless.
