Their rank and precedence shall be in the same order as mentioned in Article I. The chief of the houses of Nassau shall take the title of Duke, and the Count of Leyen that of Prince. 6. The affairs of the confederation shall be discussed in a congress of the union (Diète), whose place of sitting shall be in Francfort, and the congress shall be divided into two colleges, the kings and the princes. 7. The members of the league must be independent of every foreign power. They cannot, in any wise, enter into any other service, but that of the states of the confederation, and its allies. Those who have been hitherto in the service of a foreign power, and choose to adhere to it, shall abdicate their principality in favour of one of their children. 8. Should any of the said princes be disposed to alienate the whole or any part of his sovereignty, he can only do it in favour of the confederates. 9. All disputes, which may arise among the members of the league, shall be settled in the assembly at Francfort. 10. In this the Prince Primate shall preside, and when it shall happen, that the two colleges have to deliberate upon any subject, he shall then preside in the college of Kings, and the Duke of Nassau in that of the Princes. 11. The time, when the congress of the league, or either of the colleges, shall have particularly to assemble, the manner of the convocation, the subjects upon which they may have to deliberate, the manner of forming their conclusions, and putting them in execution, shall be determined in a fundamental statute, which the Prince Primate shall give in proposition, within a month after the notification presented at Ratisbon. This statute shall be approved of by the confederated states; this statute shall also regulate the respective rank of the members of the college of princes. 12. The Emperor shall be proclaimed protector of the confederation. On the demise of the Primate, he shall, in such quality, as often name the successor. 13. His Majesty the King of Bavaria cedes to the King of Wirtemberg, the Lordship of Wisensteig, and renounces the rights which he might have upon Weiblingen, on account of Burgan. 14. His Majesty the King of Wirtemberg makes over to the Grand Duke of Berg, the country of Bondorff, Brenlingen, and Villingen, the part of the territory of the latter city which lies on the right bank of the Brigoetz, and the city of Tuttlingen, with the manor of the same name belonging to it, on the right bank of the Danube. 15.
