A letter has been received by a member of our
Government contain- ing an assurance that the Portuguese Prime Minister, M. Jose da Silva Carvalho, has proposed to Don Pedro to •declare the Queen Donna Melia incapable of reigning. The young Queen is said to be subject to an extraordinary complaint which prevents her sleeping and occasions a ravenous appetite. - It is difficult to believe that.the Regent could be induced to adopt such advice at a time when his footing in Portugal is far from secure; but some credit is given to the statement by our Ministry.
An arrival from LiShon brings intelligence, that on the 11th instant, the Pcdroites attacked the enemy, drove them from the heights of Ferries, to the left of Santarem ; and subsequently destroyed several mills on which they depended for a supply of flour.
