A courier sent to Venice with a new cypher.
St. Germain, December 25th, 1678.
Thiscourier, whom I despatch to you, has orders not to come to your house as a courier, but to enter Venice as a tradesman, or a private French individual, who comes there on his own business: he brings for you a cypher, which you will only make use of in what regards the affairs of the Duke of Mantua, according to the occasions which you may deem necessary after the return of the Count Matthioli. We have been afraid that, for so important an affair, the cypher of the Abbé d’Estrades was too old, and had probably been discovered, in the many times it has passed through the territories of Milan. You will make use of it as usual in your ordinary despatches; but you will only write on the affairs of Mantua in the new one, which this courier brings to you.Take care to inform us exactly, of the arrival of the Count Matthioli, and of all that he shall communicate to you on the subject of his journey.
I am, &c.Pomponne.230
