London, Oct. 18.
Portuguese troops are vigilantly patrolling the northern frontier. They report that there is a considerable number of Royalists in the townships on the border. About one hundred have been captured by Spanish cavalry.—Reuter, ROYALIST CONCENTRATION, Lordon, Uct. 19.
Telegrams from Lisbon stated that Royalist bands are making forced marches for the frontier. They are reported to be concentrating in the Salgueiros mountains at the Serra de Gerez, where they are already a thousand strony.
A Republican force of lancers and infantry is in pursuit of them.
