[dateline] [Madrid, ca. 26 April 17801]
I did myself the honor of writing to you last Post in answer to yours of the 8th of
April, at that time I had suspicions that a Sir John Dalrymple who has now been here
near three weeks, was imployed by G. Britain to sound the Disposition of this Court
and in the mean time to work under Ground for the interests of his own Country. I
have been hitherto able to trace most of his motions, which are somewhat suspicious.
He came hither from Lisbon under pretence or really on account of his Ladys bad State
of health: He had a Passport from the Ministry here for that purpose as I have been
informed from those who are personally imployed about him. He hath visited several
of the Principal Grandees and all those who were most connected with Ld. Grantham.
He hath been at Aranjuez, where the Royal family is at present, hath seen the French
Embassador and as I have been told will soon set out for France. This last circumstance
occasions me to give you the present Trouble. Altho I ought to have no other apprehension
of his residence here or at Paris at this Crisis unless it be the singularity of the
Circumstance, for I know he had at one time the Confidence of his King and at least
that of part of the Administration. I have never heard that he hath done any thing
to forfeit it. If he is imployed in the way I suspect He may be induced to pay you
a visit if he passes thro Paris, which altho it may be unnecessary, induces me to
put you on your Guard. I shall endeavor to inform you punctually of his rout and shall
be always happy on every occasion of testifying to you and Mr. Dana how much I am
Your humble Sert.
