Hornstone

Definition and stakes

John MacCulloch,  On the Geology of various parts of Scotland (1814)

“ For, the hornstone, the claystone, the trap and the felspar, which constitute the bases of these several rocks, although often containing crystals of felspar, are yet perhaps as frequently destitute of that accidental substance. I am not an advocate for increasing words, and encumbering our language with unnecessary terms, but that confusion which arises from applying one term to many substances, is at least as faulty and a greater cause of error than the accumulation of an unweildy stock of synonymous ones. ”

H. Clifford Smith,  Jewellery

“ The touching-pieces (tousches) or proofs (espreuves) employed for the purpose, and considered especially efficacious against poison, were toadstones, glossopetræ, serpentine, jasper, agate and particularly the unicorn's horn. What was foisted upon the credulous public as the horn of the fabled animal was in reality the horn or tusk of a fish—the narwhal or sea-unicorn of the northern seas. Being an object of very great value, the horn was only occasionally kept entire, like the one preserved to this day at New College, Oxford. ”
