MEXICO AND THE UNITED STATES.  An outline of the following appeared in the Express of Saturday : The Hibernia, Capt. Ryrie, arrived at Liverpool a little after midnight on the morning of Saturday last. Her dates are : New York, 14th Aug. ; Boston, 16th Aug.; Halifax, 18th Aug.; Philadelphia, 14th Aug. ; Washington, 12th Aag.; New Orleans, Bth Aug.; Vera Cruz, 2nd Aug. ; Puebla, 30th July ; Mexico, 29th July; Brazos Santiago and Tampico, 31st July. The Cambria reached Halifax on the 17th inst. ; the Hibernia, and the Philadelphia of the Havre and New York line of packet steamers, both sailed from New York on the morning of the 15th inst. The Missouri, another of the French ocean steamers, put into Halifax on the 17th, short of coals, 14 days out from Cherbourg. The Washington had been ordered to remain a few weeks at New York for improvements. _ _ _  A report disseminated by the American Flag, published at Matamoros, that General Scott had entered the city of Mexico on the I ith of July, had excited quite a ferment in Washington, Philadelphia, New York, and Boston. Later and more authentic information rid Vera Cruz had, however, dispelled the illusion.  On the 30th of July, General Scott was still at Puebla ; preparing, however, for an immediate advance upon Mexico. He enly waited to be joined by General Peirce, who was expected to reach Puebla in the first week of August. The attack upon Peirce's detachment at Puente Nacional, of which vague rumours only were received by last mail, was repulsed with considerable logs to the Mexicans. Notwithstanding_the natural strength of the position occupied by the Mexican guerillas, the Americans carried it in gallant style. They reserved their fire till within 100 yards of the enemy, and then opened it with murderous effect, forcing the Mexicans to an immediate retreat. General Peirce reached Perote without any further attempts to interrupt his march, and there he was joined by Smith's brigade, which Gen. Scott had despatched to meet him. The news from Mexico is very vague. In order to be free to act, government had suspended the publication of all newspapers, except the official organ. The Yew Orleans Delta states that the Mexican Congress had met and adjourned, without coming to any determination respecting the propositions of the government at Washington. It was understood that they sought to throw on the executive the entire responsibility of conducting the war. Santa Anna was represented by one account as having held is council of general officers, at which it was resolved to seek one more general engagement. The fortifications of Mexico were said to be completed ; and the armed force assembled in the capital; was stated at 25,000. General Valencia had arrived in the capital with 4,000 men. Alvarez was also there, and had had several long interviews with Santa Amid. As tr as Mexico is concerned, the rest is all conjecture. Mr. Kendall, of the New Orleans Picayune, who is at Puebla, represents the chances of peace in an unfavourable light; other communications to that paper are more sanguine, representing the Peaaan as gaining ground. On all hands, how-1 ever, . rist's mission is regarded as a failure, and a renewal of hostilities is looked upon even by those who anticipate little more than a nominal resistance as an inevitable prelude to peace. The old report of Santa Anna aiming at the dictatorship, with a view to patch up a peaee, was revived. The foreign merchants in Mexico were said to be anxious tor General Scott's arrival, and confident that he could take the city without difficulty. A rumour had spread among the Americans to the effect that the English legation was secretly exerting its influence to keep the Americans out of the capital. Commodore Perry had withdrawn his force from
