And therein we find a discussion of the word "beryl":
BERYL, s. This word is perhaps a very ancient importation from India to
the West, it having been supposed that its origin was the Skt. vaidurya, [the latter is a word for beryl] ... Professor Max Muller has treated of the possible relation between vaidurya and viddla, 'a cat,' and in connection with this observes that "we should, at all events, have learnt the useful lesson that the chapter of accidents is sometimes larger than we suppose."—(India, What can it Teach us? p. 267).
Chapter of accidents: what a nice phrase. One does wonder how far back the connection of cats and gemstones goes.
