Since my letter of the 18th. instant, I have received yours of the 14th.

As however my letter of the 18th: (of which one copy has been sent by the Mail, and another by Sea) will have occasioned such a different impression with respect to the Marquis and the other persons in the service of Spain, it is not to be apprehended that any future question will arise with respect to a similar courtesy. I am &c.
