"4th. It seems expedient, that the representations mentioned in this article be made by the party aggrieved, and that the Ministers of the other confederate powers support those remonstrances in the most forcible and efficacious manner. "5th. We feel all the importance of this consideration, and to render it clear, it is necessary to distinguish the case. If any one of the allied powers should suffer itself to be drawn in by motives contrary to the established principles of a neutrality and perfect impartiality, should injure its laws, or extend their bounds, it cannot certainly be expected that others should espouse the quarrel; on the contrary, such a conduct would be deemed an abandoning the ties which unite them. But if the insult offered to one of the allies should be hostile to the principles adopted and announced in the face of all Europe, or should be marked with the character of hatred and animosity, inspired by resentment at these common measures of the confederacy, which have no other tendency than to make, in a precise and irrecoverable manner, laws for the liberty of commerce, and the rights of every neutral nation, then it shall be held indispensable for the united powers to make a common cause of it, (at sea only) without its being a groundwork for other operations, as these connexions are purely maritime, having no other object than naval commerce and navigation. From all that is said above, it evidently results, that the common will of all, founded upon the principles admitted and adopted by the contracting parties, must alone decide, and that it will always be the fixed basis of the conduct and operations of this union. Finally, we shall observe, that these conventions suppose no other naval armament than what shall be conformable to circumstances, according as these shall render them necessary, or as may be agreed. It is probable, that this agreement, once ratified and established, will be of the greatest consequence; and that the belligerent powers will find in it sufficient motives to persuade them to respect the neutral flag, and prevent their provoking the resentment of a respectable communion, founded under the auspices of the most evident justice, and the sole idea of which is received with the universal applause of all impartial Europe."

Sir, The errand of Mr Cumberland to Madrid is a mere finesse of the British Ministry, intended to aid the stockjobbers to keep up the stocks, aid the loan, and the canvass for an election, and lull the belligerent powers, while they prepare their measures for future enterprises and another campaign. They have carried this plot so far, that I see some paragraphs in the foreign papers, which seem intended to counteract it.
