Among those collected by Sir Thomas Browne:
Number 9. An Etiudros Alberti or Stone that is apt to be always moist: usefull unto drie tempers, and to be held in the hand in Fevers instead of Crystal, Eggs, Limmons, Cucumbers.
Number 11. A neat painted and gilded Cup made out of the Confiti di Tivoli and formed up with powder’d Egg-shells; as Nero is conceived to have made his Piscina admirabilis, singular against Fluxes to drink often therein.
