I beg to offer my best respects to Lady Holland and Mr. Allen, and have the honour to be, &c. R. CAMPBELL. P.S.--Though the Cortes in a body are to have the _tratamiento of Majesty_, the individual members are to have no _tratamiento_ nor any badge of distinction as members of Cortes. When the Regency took the oaths to the Cortes on the evening of the 24th, the Bishop of Orense did not come, saying he was fatigued and much indisposed, and he has since declined to take the oaths from some _scruple of conscience_, of what nature we do not know. The Cortes were sitting yesterday in a secret committee of the whole, deliberating upon a communication from the Regency. _Mr. R. Campbell to Lord Holland._ Cadiz, Dec. 10, 1810. MY LORD,--Being much hurried at present I must refer your Lordship to the public reports for an account of the further proceedings of the Cortes and of the events which have lately taken place in this country. I shall only say in general that we are still full of confidence. A measure, which I have taken the liberty of strongly recommending to some of my friends among the deputies, will probably be moved in the Cortes this day or to-morrow. It is to pass a decree making it a fundamental law of the state that any King of Spain or Prince of the blood royal who shall marry a _foreigner_ without the consent of the Cortes, shall by that act forfeit his title to the crown. The subject of this decree, independent of its general policy, is immediately to anticipate any new trick or stratagem which Bonaparte may probably devise, should the campaign in Portugal prove, as we hope, signally disastrous to his arms, by marrying Ferdinand to a Frenchwoman or an Austrian, and bringing him to Spain as King, in order to create new factions and disunion. This law will probably be proposed by Arguelles, and I have little doubt will pass. Your Lordship will perceive from this that we are at present more afraid of the artifices than of the arms of Napoleon. Some discussion will likewise soon take place in the Cortes with respect to the assumption of the title of _Majesty_ by them; a measure which, I was aware, would be liable to much misconstruction in England. I shall write your Lordship more fully on this and some other subjects by next packet; in the mean time, your Lordship may be assured that there was no intention, by the assumption of this title, to degrade the royal authority. I beg leave to offer my best respects to Lady Holland and Mr. Allen, and have the honour to be, &c. R. CAMPBELL. _Mr. R. Campbell to Lord Holland._
