The story itself is not, much amiss, and therefore you shall have it.
A Count of a very great family, and with whom I was very intimate, being married to a fair lady, who had formerly been courted by one who was at the wedding, all his friends were in very great fear; but especially an old lady his kinswoman, who had the ordering of the solemnity, and in whose house it was kept, suspecting his rival would offer foul play by these sorceries.

Which fear she communicated to me.

I bade her rely upon me: I had, by chance, about me a certain flat plate of gold, whereon were graven some celestial figures, supposed good against sunstroke or pains in the head, being applied to the suture: where, that it might the better remain firm, it was sewed to a ribbon to be tied under the chin; a foppery cousin-german to this of which I am speaking.

Jaques Pelletier, who lived in my house, had presented this to me for a singular rarity.
I had a fancy to make some use of this knack, and therefore privately told the Count, that he might possibly run the same fortune other bridegrooms had sometimes done, especially some one being in the house, who, no doubt, would be glad to do him such a courtesy: but let him boldly go to bed.

For I would do him the office of a friend, and, if need were, would not spare a miracle it was in my power to do, provided he would engage to me, upon his honour, to keep it to himself; and only, when they came to bring him his caudle,--[A custom in France to bring the bridegroom a caudle in the middle of the night on his wedding-night]-- if matters had not gone well with him, to give me such a sign, and leave the rest to me.
