The expedition of Don PEDRO left St. Michael's on the
26th of June ; the last detachment of the troops embarked on the previous ddy: They are described as in the highest spirits and best possible equipment. Don PEDRO made a spirit-stirring .speech to them - previous to their 'embarkation: he also published a proclamation of a most liberal tenor; in which, among 'other. professions, 'he says- " To deliver the oppressed—to re-establish order—to restore the legitimate throne of my auguSt daughter, and with it the Constitutional Charter which I gave you, and Which you freely swore to maintain,—such are the motives which have induced ioe (con6ding in your co-operation) to place myself at the head of this noble and just cause.' These are my only views. On the 27th, the- squadron lost.sight of St. Michael's, near to--- which place it had been becalmed on the day it weighed anchor. The latest direct news come only down. to the 30th; but there was a ruitiour yesterday that the expedition had reached the mouth of the Tagus,—where it is not supposed it will experience any diffi- culty in effeeting a landing, and we would hope, as little in effecting its most legitimate purpose of driving from the throne he has so long polluted one of the most worthless of Princes.
