The following must probably be one of those which good Lucantonio did not make trial of, but took on trust undoubtingly, from his faith in the noble author's "greatness:" "To make a toad cast his stone. Take a toad of those which have a red head. Place him in a cage, and put the cage upon a piece of scarlet cloth; and early in the morning, set it in the ray of the rising sun. The toad will look fixedly at the sun; and you must let him remain there for three hours. And at the end of that time he will cast forth a stone which has three virtues: 1st, It is specific against poison; 2nd, It is good to staunch blood; 3rd, When a horse is in pain, grate some of the stone, and make him drink it." [Sidenote: HER MEDICAL SECRETS.] There are among these valuable secrets, waters "to make iron hard;" "to make it as brittle as glass;" "to dissolve pearls;" "to dissolve all metals;" &c., &c. There are no less than thirteen different specifics against witchcraft. Then, if you would know whether a sick person will recover, you must "clean the face of the sick with warm paste, and then give the paste to a dog. If the dog should eat the paste, the sick man will recover; if not, he will die." Lastly, there are a great number of a kind that, less than any of the others, should have been of any interest to the recluse of the Murate; such as love philtres, specifics against sterility and other kindred inconveniences. Several are for purposes set forth by the noble lady with the utmost cynical directness of terms, but which cannot, under any veil of phrase, be even indicated here. And some instructions there are, which would place any modern English man or woman acting on them, in a very disagreeable position in the dock of the Old Bailey; but which are here, by some theological sharp practice, so cleverly and piously managed, as to attain their object, "_senza carico di coscienza_." It would seem, too, that, startling as is the cynicism of some of the language which Messer Lucantonio has not scrupled to copy in his best text-hand, some of the lady's secrets must have been of a yet more abominable description. For passages in cipher frequently occur in a context, which indicates that such has been the reason for so veiling them.
