Var. C is a yellow, ochry clay-iron-stone, very soft and not used for melting. It has a reputation as a medicine against head-ache, hears the names, Syn. Manju-ishi, Dango-ishi, Tsuchi-dango, Dango-wa and is found in Buzen Nakatsu, Awa, Higami-gun, Suwo, Tö, Oshu Tsugaru, Hoki, Noto, Kai Arayi-yama.

B.—Dodekahedral Pyrites is kept by the Japanese for a wholly different use to the former. They distinguish, according to the colour, two kinds, namely, Syn. Ho-kin-ge, Kana-Zako=pyrites with a yellow (gold) colour and, Syn. Ho-gin-ge, Do-gin,
