Late last night, a whole family came here for protection; the Señora ——- with ——-, nurse, and baby, etc. She had remained very quietly in her own house, in spite of broken windows, till the bullets whizzed past her baby's bed. This morning, everything remains as it was the first day—the president in the citadel, the rebels in the palace. The government are trying to hold out until troops arrive from Puebla. In an interval of firing, the—-Secretary contrived to make his way here this morning. The English Minister's house is also filled with families, it being a little out of the line of fire. Those who live in the Square, and in the Calle San Francisco are most exposed, and the poor shopkeepers in the Parian are in a state of great and natural trepidation. I need not say that the shops are all shut.

19th.—Dr. Plan, a famous French physician, was shot this morning, as he was coming out of the palace, and his body has just been carried past our door into the house opposite.

The Señorita ——- having imprudently stepped out on her balcony, her house being in a very exposed street, a pistol-ball entered her side, and passed through her body. She is still alive, but it seems impossible that she can recover. The Prior of San Joaquin, riding by just now, stopped below the windows to tell us that he fears we shall not remain long here in safety, as the pronunciados have attacked the Convent of La Concepción, at the end of the street.

My writing must be very desultory. Impossible to fix one's attention on anything. We pass our time on the balconies, listening to the thunder of the cannon, looking at the different parties of troops riding by, receiving visitors, who, in the intervals of the firing, venture out to bring us the last reports—wondering, speculating, fearing, hoping, and excessively tired of the whole affair.

Gomez Farias, the prime mover of this revolution, is a distinguished character, one of the notabilities of the country, and has always maintained the same principles, standing up for "rapid and radical reform." He is a native of Guadalajara, and his literary career is said to have been brilliant. He is also said to be a man of an ardent imagination and great energy. His name has appeared in every public event. He first aided in the cause of Independence, then, when deputy for Zacatecas, showed much zeal in favour of Yturbide—was afterwards a warm partisan of the federal cause—contributed to the election of General Victoria; afterwards to that of Pedraza—took an active part in the political changes of '33 and '34; detests the Spaniards, and during his presidency endeavoured to abolish the privileges of the clergy and troops—suppressed monastic institutions—granted absolute liberty of opinion—abolished the laws against the liberty of the press—created many literary institutions; and whatever were his political errors, and the ruthlessness with which in the name of liberty and reform he marched to the attainment of his object, without respect for the most sacred things, he is generally allowed to be a man of integrity, and even by his enemies, an enthusiast, who deceives himself as much as others. Now in the hopes of obtaining some uncertain and visionary good, and even while declaring his horror of civil war and bloodshed, he has risen in rebellion against the actual government, and is the cause of the cruel war now raging, not in the open fields or even in the scattered suburbs, but in the very heart of a populous city.

This morning all manner of opinions are afloat. Some believe that Santa Anna has started from his retreat at Manga de Clavo, and will arrive to-day—will himself swallow the disputed oyster (the presidential chair), and give each of the combatants a shell apiece; some that a fresh supply of troops for the government will arrive to-day, and others that the rebels must eventually triumph. Among the reports which I trust may be classed as doubtful, is, that General Urrea has issued a proclamation, promising three hours' pillage to all who join him. Then will be the time for testing the virtues of all the diplomatic drapeaux. In the midst of all, here comes another.

"Address of His Excellency, Señor Don Valentin Gomez Farias, charged provisionally with the government of Mexico, and of the General-in-Chief of the Federal army, to the troops under his command."

"Companions in arms:—No one has ever resisted a people who fight for their liberty and who defend their sacred rights. Your heroic endeavours have already reduced our unjust aggressors almost to complete nullity. Without infantry to cover their parapets, without artillery to fire their pieces, without money, without credit, and without support, they already make their last useless efforts. On our side, on the contrary, all is in abundance (sobra), men, arms, ammunition, and money, and above all, the invincible support of opinion;—while the parties which adhere to our pronunciamento in all the cities out of the capital, and the assistance which within this very city is given by every class of society to those who are fighting for the rights of the people, offer guarantees which they will strictly fulfil to all the inhabitants of the country, natives as well as foreigners. Our enemies, in the delirium of their impotence, have had recourse to their favourite weapon, calumny. In a communication directed to us, they have had the audacity to accuse you of having attacked some property. Miserable wretches! No, the soldiers of the people are not robbers; the cause of liberty is very noble, and its defence will not be stained by a degrading action. This is the answer given to your calumniators by your chiefs, who are as much interested in your reputation as in their own. Soldiers of the people! let valour, as well as all other civic virtues, shine in your conduct, that you may never dim the renown of valiant soldiers and of good citizens.

"Valentin Gomez Farias."

"José Urrea."
