[3251] “Ox-heart.” Supposed to be a sort of Turquois, Hardouin says.

[3252] “Thunder-stone.”

[3253] “Clod-stone.” It may possibly have been a kind of Geodes. See B. xxxvi. c. [32]. Dalechamps, however, identifies it with Crapaudine, Toad-stone, or Bufonite, supposed in former times to be produced by the toad, but in reality the fossil tooth of a fish.

[3254] See B. iii. c. 4.

[3255] See B. xxxiv. c. [22], and Chapter [65] of this Book.

[3256] Identical, probably, with the Callaina of Chapter [33], our Turquois.

[3257] Lapis lazuli.

[3258] “Smoke-stone.” Identical with the jasper called “capnias,” in Chapter [37].

[3259] In Chapter [37] of this Book.

[3260] “Cappadocian stone.”
