To prepare match so that it will burn though it be wet.

To shoot men or birds with powder alone so that they shall lie as dead for a while and yet rise up again without harm.
To give a man double strength without the use of carbine-thistle or other such forbidden means.
If a sally from a fortress be checked, so to spike the enemy's guns in a moment that they must burst.
To spoil a man's gun so that it will scare all game to cover till it be again cleansed with a certain other substance.

A special art to provide that no bullet may hit thee.
To prepare an instrument by means of which, specially on a still night, a man can in wondrous wise hear all that sounds or is spoken at an incredible distance (otherwise clean impossible and supernatural); very profitable for sentries and specially in sieges, etc. (bk. iii., chap. 1.).
In like manner were many arts described in the said catalogue which mine host had found and read: so he came to me himself into my chamber, shewed me the list, and asked whether 'twas possible that these things could be done by natural means; for that could he scarce believe; yet must confess that in his youth, when he served as a page in Italy with Field-marshal von Schauenburg, it was given out by some that the princes of Savoy were proof against bullets: which the said Field-marshal desired to make proof of in the person of Prince Thomas, whom he then kept besieged in a fortress; for when on a time both sides had agreed on a truce for an hour to bury the dead and to confer together, he had commanded a corporal of his regiment, that was held to be the best marksman in the whole army, to take aim at the said prince while he should be standing on the parapet of the wall for a parley, and so soon as the hour agreed upon should end, to fire at him with his piece, with which he could put a lighted candle out at fifty paces: that this corporal had taken careful note of the time and kept the said prince under observation the whole time of the truce, and at the very moment when it ended with the first stroke of the hour, fired at him: yet had his piece, contrary to all belief, missed fire, and before the corporal could make ready again the prince was gone behind the parapet; whereupon the corporal pointed out to the Field-marshal, who had likewise come to him on the trenches, a Switzer of the prince's guard, at whom he aimed and hit him in such fashion that he rolled over and over; wherefrom it plainly appeared that there was something in the story that no prince of the house of Savoy could be hit or harmed. Yet whether this was brought about by such arts, or whether perchance the said princely house enjoyed a special grace from God, being, as 'twas said, sprung from the race of the royal prophet David, he knew not.
