The city was divided into four quarters: this division is still preserved, in the limits assigned to the quarters of St. Paul, St. Sebastian, St. John, and St. Mary; and the present streets have, for the most part, the same direction as the old ones. But what gives to this city a peculiar and distinctive character is, that it is entirely on the continent, between the extremities of the two lakes of Tezcuco and Chalco. This has been occasioned by the gradual draining of the great lake, and the consequent drying up of the waters around the city. Hence Mexico is now two miles and half from the banks of the former, and five miles and half from those of the latter.

Adorned with numerous teocallis, (or temples,) like so many Mahometan steeples, surrounded with water and embankments, founded on islands covered with verdure, and receiving, hourly, in its streets, thousands of boats, which vivified the lake, the ancient Mexico, according to the accounts of the first conquerors, must have resembled some of the cities of Holland, China, or the Delta of Lower Egypt.

As reconstructed by the Spaniards, it exhibits, at the present day, perhaps a less vivid, though a more august and majestic appearance, than the ancient city. With the exception of Petersburg, Berlin, Philadelphia, and some quarters of Westminster, there does not exist a place of the same extent, which can be compared to the capital of New Spain, for the uniform level of the ground on which it stands, for the regularity and breadth of the streets, and the extent of its public places. The architecture is, for the most part, in a pure style; and many of the edifices are of a very beautiful structure. The exterior of the houses is not loaded with ornaments. Two sorts of hewn stone, give to the Mexican buildings an air of solidity, and sometimes even of magnificence. There are none of those wooden balconies and galleries to be seen, which so much disfigure all the European cities in both the Indies. The balustrades and gates are all of iron, ornamented with bronze; and the houses, instead of roofs, have terraces, like those in Italy, and other southern countries of the old continent.

Mexico has, of late, received many additional embellishments. An edifice, for the School of Mines, which was built at an expence of more than £.120,000 sterling, would adorn the principal places of Paris or London. Two great palaces have been constructed by Mexican artists, pupils of the Academy of Fine Arts. One of these has a beautiful interior, ornamented with columns.

But, notwithstanding the progress of the arts, within the last thirty years, it is much less from the grandeur and beauty of the monuments, than from the breadth and straightness of the streets; and much less from its edifices, than from its uniform regularity, its extent and position, that the capital of New Spain attracts the admiration of Europeans. M. De Humboldt had successively visited, within a very short space of time, Lima, Mexico, Philadelphia, Washington, Paris, Rome, Naples, and the largest cities of Germany; and notwithstanding unavoidable comparisons, of which several might be supposed disadvantageous to the capital of Mexico, there was left on his mind, a recollection of grandeur, which he principally attributed to the majestic character of its situation, and the beauty of the surrounding scenery.

In fact, nothing can present a more rich and varied appearance than the valley of Mexico, when, in a fine summer morning, a person ascends one of the towers of the cathedral, or the adjacent hill of Chapoltepec. A beautiful vegetation surrounds this hill. From its summit, the eye wanders over a vast plain of richly-cultivated fields, which extend to the very feet of colossal mountains, that are covered with perpetual snow. The city appears as if washed by the waters of the lake of Tezcuco, whose basin, surrounded by villages and hamlets, brings to mind the most beautiful lakes of the mountains of Switzerland. Large avenues of elms and poplars lead, in every direction, to the capital; and two aqueducts, constructed over arches of great elevation, cross the plain, and exhibit an appearance equally agreeable and interesting.

Mexico is remarkable for its excellent police. Most of the streets have broad pavements; and they are clean, and well lighted. Water is, every where, to be had; but it is brackish, like the water of the lake. There are, however, two aqueducts, by which the city receives fresh-water, from distant springs. Some remains of the dikes or embankments, are still to be seen: they, at present, form great paved causeys, across marshy ground; and, as they are considerably elevated, they possess the double advantage, of admitting the passage of carriages, and restraining the overflowings of the lake. This city has six principal gates; and is surrounded by a ditch, but is without walls.

The objects which chiefly attract the attention of strangers, are 1. The Cathedral, which is partly in the Gothic style of architecture, and has two towers, ornamented with pilasters and statues, of very beautiful symmetry. 2. The Treasury, which adjoins to the palace of the viceroys: from this building, since the beginning of the 16th century, more than 270 millions sterling, in gold and silver coin, have been issued. 3. The Convents. 4. The Hospital, or rather the two united hospitals, of which one maintains six hundred, and the other eight hundred children and old people. 5. The Acordada, a fine edifice, of which the prisons are spacious and well aired. 6. The School of Mines. 7. The Botanical Garden, in one of the courts of the viceroy's palace. 8. The edifices of the University and the Public Library, which, however, are very unworthy of so great and ancient an establishment. 9. The Academy of Fine Arts.

Mexico is the see of an archbishop, and contains twenty-three convents for monks, and fifteen for nuns. Its whole population is estimated at one hundred and forty thousand persons.

On the north-side of the city, near the suburbs, is a public walk, which forms a large square, having a basin in the middle, and where eight walks terminate.
