The British Museum is an enormous building, light and airy. In it, free to the public, is an unsurpassed collection of preserved animals, which can better be imagined than described. How wide is the field to which one is introduced, in the works of art or places of entertainment, in this vast metropolis! Museums and galleries abound. Accessible to the public, they are practically free, and better than can be found elsewhere in the world. How abundant are the means of travel. The cab system is here at its perfection. The low prices are regulated by law. It costs one passenger a shilling, and two passengers a shilling and sixpence, to go a reasonable distance,--farther than from the Boston North End depots to those at the other part of the city. Cabs are plenty and are to be found standing in the centre of all principal thoroughfares. It is the law also that a tariff-card, in readable type, shall be put up inside of every cab. Omnibuses abound, always with seats on the top as well as inside. The horse-cars, or trams, are heavier than ours, and not so handsome, but they are clean and well managed. Like the omnibuses, they have seats on top, where the travellers sit back to back. Then there is the underground railway. This runs almost around the entire city, and has a double track. Steam trains, of many carriages, are constantly passing both ways. At convenient points are stations where passengers descend and return by wide stairways through well-lighted and spacious trainhouses. This road is in all respects a great success. Perhaps half of it is through tunnels, but much of it is open to the sky, and the cars are lighted artificially. So frequent are the trains that one goes to the station at random, as he would to an omnibus, sure of not having long to wait. We have spoken of the oft-running and well-patronized boats on the river. London is perfectly supplied with facilities for transit. Not for a moment would the over-crowded horse-cars, often seen here in our Boston be tolerated. We do not remember once standing in any public conveyance in England or on the Continent.
