The agents of Don PEDRO in London have published what
they call an official bulletin, containing an account of an attack upon the Miguelite positions on the north of Oporto, which were car- ried with a loss of 600 men to the Miguelites, and a very slight loss to the garrison. Provisions and ammunition are also said to have been landed in considerable abundance at Oporto, and the spirit of the inhabitants and the soldiery is represented as being excellent. The Standard throws discredit upon this account; which, indeed, is liable to suspicion, inasmuch as it does not very plainly appear how the intelligence could have been received. The steam-boat which arrived from Vigo four days ago might have brought it; but how does it happen that the news was not more quickly promulgated?
