OR a description of Quartz Cat's Eye, and the True Cat's Eye, see pp.
211 to 213. Thin fibres of asbestos interspersed with regularity in the
quartz give rise to the characteristic appearance of this stone. It is
brought chiefly from Ceylon, and from Hof in Bavaria.
The
Crocidolite, or "Wood Cat's Eye," of South Africa, known also as "
Tiger's Eye " and " Hawk's Eye," has been described at pp. 257, 258.
Neither the quartz Cat's Eye, nor the South African Crocidolite is of more than trivial value.
