Pisa is one of the most beautiful cities I have seen in Italy. The extreme elegance and comfort of the houses, the spacious Quai on the Arno which furnishes a most agreeable promenade, the splendid style of architecture of the _Palazzi_ and public buildings, the cleanliness of the streets, the salubrity of the climate, the mildness of the winter, the profusion and cheapness of all the necessaries of life, and above all the amenity and simplicity of the inhabitants, combine to make Pisa an agreeable and favorite residence. Yet the population having much decreased there appears an air of melancholy stillness about the city and grass may be seen in some of the streets. This decay in population causes lodgings to be very cheap. The most striking object in Pisa is the leaning tower _(Torre cadente)_ and after that the Cathedral, Baptistery, and _Campo Santo_ which are all close to the tower and to each other. Imagine two fine Gothic Churches in a square or place like Lincoln's Inn Fields; a large oblong building nearly at right angles with the churches and inclosing a green grass plot in its quadrangle and a leaning tower of cylindrical form facing the churches: and then you will have a complete idea of this part of Pisa. I must not omit to mention that there is a breed of camels here belonging to the Grand Duke; I believe it is the only part of Europe except Turkey where the breed of camels is attempted to be propagated. LEGHORN, 17 Novr. I left Pisa for Leghorn on the morning of the 15th November, and after a drive of two hours in a cabriolet I arrived at the latter place and put up at the _Aquila Nera._ The distance between Pisa and Leghorn is only 10 or 11 miles and a plain with few trees, either planted in corn or in pasturage, forms the landscape between the two cities. Leghorn (Livorno), being a modern city, does not offer anything remarkably interesting to the classical traveller either from its locality or its history. Founded under the auspices of the Medici it has risen rapidly to grandeur and opulence, and has eclipsed Genoa in commerce. It is a remarkably handsome city, the streets being all broad and at right angles; the _Piazze_ are large and the _Piazza Grande_ in particular is magnificent. There is a fine broad street leading from the _Piazza Grande_ to the Port. The Port and Mole are striking objects and considerable commercial bustle prevails there.
