M. MENDIZABEL, the Portuguese Commissioner, arrived in London at a
late hour this afternoon, from Lisbon, having left that place on Sunday last, in the Salamander. He was the bearer of despatches for the Portuguese Ambassador, but they had not been delivered up to a late hour in the evening. M. MENDIZABEL has, however, communi- cated sufficient to tranquillize the friends of the Liberal party in Por- tugal, who had begun to apprehend that the death of the King of Spain would give the Miguelites fresh vigour, by procuring for them a strong point d'appui. On the contrary, MIGUEL'S army had materially diminished, whilst that of PEDRO had considerably increased. On the 2d and 3d instant, the Pedroite forces were reviewed, and found to be in excellent condition and full of ardour. At a Cabinet Council, at which Don PEDRO assisted, it was resolved to make a general attack upon the enemy, on the 10th instant. On the 4th, the division which was at Torres Vedras made a movement, and took up a new position ; and on the 5th several other corps made the necessary dispositions for an at- tack. It was judged expedient, however, to defer this until the 10th ; when every thing would be prepared for a trial of strength. The inhabi- tants of Lisbon were full of enthusiasm, and Don PEDRO was popular in a high degree. Before the Salamander left Lisbon, the French Charge d'Affaires had received very important despatches from his Government, the consequence of which was a more close communication with the Regency. It was reported, and generally believed, that the French Government, in anticipation of the death of the King of Spain, had commissioned the Charge d'Affaires to establish very close relations with the Portuguese Regency.
