From _Mexico_ later advices have been received,--to August 22d from the capital and the 29th from Vera Cruz. The hostility of the government to the fulfillment of its treaty stipulations concerning the Tehuantepec Canal continues unabated; and it is stated that two vessels sent from New Orleans to commence the work were seized by the Mexican authorities. The financial condition of the country continues to engross attention, but no one of the numerous projects offered for its relief seems likely to be adopted.
