CHAP. 53.—LEROS.
The stone called "leros"[1] is similar in appearance, but does
not produce the same effects. It is a crystal, with streaks of
white and black running across it.
1. The reading is doubtful, "zeros" and "erros" being given by some
MSS. Ajasson hazards a conjecture that it may have been a variety of
quartz, formed of a concretion of agates united by a cement of a similar
nature.
