The Countess del V—-e has just sent me a beautiful bird with the most gorgeous plumage of the brightest scarlet and blue. It is called a huacamaya, and is of the parrot species, but three times as large, being about two feet from the beak to the tip of the tail. It is a superb creature but very wicked, gnawing not only its own pole, but all the doors, and committing great havoc amongst the plants, besides trying to bite every one who approaches it. It pronounces a few words very hoarsely and indistinctly, and has a most harsh, disagreeable cry. In fact it presumes upon its beauty to be as unamiable as possible.

I prefer some beautiful little humming-birds (chupamirtos as they are called here) which have been sent me, and which I am trying to preserve alive, but I fear the cold will kill them, for though we see them occasionally here, hanging by their beaks upon the branches of the flowers, like large butterflies, and shaking their brilliant little wings so rapidly that they seem to emit sparkles of coloured light; still this is not their home; properly speaking, they belong to the tierra caliente. These little birds are of a golden green and purple, and are so tame, that whilst I am writing I have two on my shoulder and one perched on the edge of a glass, diving out its long tongue for sugar and water. Our live stock is considerable: we have Guinea fowls, who always remind me of old maiden ladies in half-mourning, and whose screaming notes match those of the huacamaya; various little green parrots; a scarlet cardinal, one hundred and sixty pigeons in the pigeon-house, and three fierce dogs in conspicuous situations.

I received a very polite letter today from the Señora de Santa Anna, and as it was enclosed in a few lines from Santa Anna himself, I send you his autograph, for I doubt much whether we have seen the last of that illustrious personage, or whether his philosophic retirement will endure for ever.

I have been endeavouring lately to procure permission from Señor Posada, who is shortly to be consecrated archbishop, to visit the convents of nuns in Mexico. Señor C—-o, secretary of state, our particular friend, has been kind enough to interest himself in the matter, though with indifferent hopes of success. A few days ago he sent me his correspondence with Señor Posada, who observes that the vice-queens alone had the privilege of the entree, and seems to hesitate a good deal as to the advisableness of granting a permission which might be considered a precedent for others. However, I think he is too amiable to resist our united entreaties. I hold out as an argument, that C—-n, being the duplicado of the queen herself, my visit is equal to that of the vice-queen, which argument has at least amused him. His consecration is fixed for the 31st of May.

Don Pedro Fonti, the last archbishop named in the time of the Spanish dominion, having renounced the mitre, three illustrious churchmen were proposed to fill the vacant place: this Don Manuel Posada, Don Antonio Campos, and Dr. Don José María de Santiago. The first was chosen by the Mexican government, and was afterwards proclaimed in the Roman Consistory last December, with the approbation of Gregory XVI. They are now only waiting for the pontifical bulls, which are daily expected from Rome; and it is said that the ceremony, which will take place in the cathedral, will be very magnificent.

April 3rd.—Accompanied by the—Minister, we spent yesterday in visiting the Mineria, the Botanic Garden, the Museum, etc., all which leave a certain disagreeable impression on the mind, since, without having the dignity of ruins, they are fine buildings neglected. The Mineria, or School of Mines, the work of the famous architect and sculptor Tolsa, is a magnificent building, a palace whose fine proportions would render it remarkable amongst the finest edifices of any European country. All is on a great scale, its noble rows of pillars, great staircases, large apartments and lofty roofs, but it reminds one of a golden aviary, containing a few common sparrows. Several rich Spaniards contributed more than six hundred thousand dollars to its construction. We were shown through the whole of this admirable building by the director, who occupies a very handsome house attached to it. But however learned the professors may be,—and amongst them is the scientific Señor del Rio, now very old, but a man of great learning and research,—the collection of minerals, the instruments and models, are all miserable and ill kept.

The Botanic Garden, within the palace, is a small ill-kept enclosure, where there still remain some rare plants of the immense collection made in the time of the Spanish government, when great progress was made in all the natural sciences, four hundred thousand dollars having been expended in botanical expeditions alone. Courses of botanical lectures were then given annually by the most learned professors, and the taste for natural history was universal.

El Arbol de las Manitas (the tree of the small hands) was the most curious which we saw in the garden. The flower is of a bright scarlet, in the form of a hand, with five fingers and a thumb; and it is said that there are only three of these trees in the republic. The gardener is an old Italian, who came over with one of the viceroys, and though now one hundred and ten years old, and nearly bent double, possesses all his faculties. The garden is pretty from the age of the trees, and luxuriance of the flowers, but melancholy as a proof of the decay of the science in Mexico. The palace itself, now occupied by the president, formerly belonged to Cortes, and was ceded by his descendants to the government. In exchange they received the ground formerly occupied by the palace of the Aztec kings, and built on it a very splendid edifice, where the state archives are kept, and where the Monte Pio (the office where money is lent on plate, jewels, etc.) now is, the director of which is Don Francisco Tagle, whose apartments within the building are very elegant and spacious.

The Museum within the University, and opposite the palace, in the plaza called del Volador, contains many rare and valuable works, many curious Indian antiquities, but they are ill arranged. On the walls are the portraits of the vice-kings, beginning with Hernan Cortes. We spent a long while here examining these antiquities; but we have seen nothing in Mexico to equal the beauty of the colossal equestrian statue in bronze of Charles IV, placed on a pedestal of Mexican marble, which stands in the court of the University, but formerly adorned the middle of the square. It is a magnificent picture of sculpture, the masterpiece of Tolosa, remarkable for the noble simplicity and purity of its style, and was made at the expense of an ex-viceroy, the Marquis of Branciforte. We also saw the goddess of war lying in a corner of the court, beside the stone of sacrifices, which we had already been shown.

To-day we have been visiting the Academy of painting and sculpture, called the Academy of Fine Arts, of which I unfortunately recollected having read Humboldt's brilliant account, in my forcibly prolonged studies on board the Jason, and that he mentions its having had the most favourable influence in forming the national taste. He tells us that every night, in these spacious halls, well illumined by Argand lamps, hundreds of young men were assembled, some sketching from the plaster-casts, or from life, and others copying designs of furniture, candelabras and other bronze ornaments; and that here all classes, colours, and races, were mingled together; the Indian beside the white boy, and the son of the poorest mechanic beside that of the richest lord. Teaching was gratis, and not limited to landscape and figures, one of the principal objects being to propagate amongst the artists a general taste for elegance and beauty of form, and to enliven the national industry. Plaster-casts, to the amount of forty thousand dollars, were sent out by the King of Spain, and as they possess in the academy various colossal statues of basalt and porphyry, with Aztec hieroglyphics, it would have been curious, as the same learned traveller remarks, to have collected these monuments in the courtyard of the Academy, and compared the remains of Mexican sculpture, monuments of a semi-barbarous people, with the graceful creations of Greece and Rome.
