In the _Regent's Park_ a new Terrace and other buildings, are in progress; the great Colosseum is nearly finished, and the _Zoological Gardens_ have excited unusual popularity. No less than 130,000 visiters have been admitted to view the gardens and the vivarium within the year 1828. On the east side of the Park is a mass of buildings appropriated to _St. Katherine's Hospital_, consisting of a chapel in the centre, with a group of dwellings on each side, and a detached mansion for the master. South of this is a series of buildings, called _Cumberland Terrace_, raised from the designs of Mr. Nash, which is abundantly adorned with columns, arches, statues, and basso-relievo. The _Colosseum_, in the same Park, is a building of great dimensions, and novel appropriation, and therefore calculated to excite very popular attention. Near this is the _Diorama_, an edifice of singular construction, destined for the public display of two pictures. A new line of communication from this Park to Pall Mall has been completed within the last few years, by a wide and handsome road called _Regent Street_. _London University_--The situation of the first University founded in this immense city is most peculiarly favourable, being equally removed from the busy and confined part of the metropolis, and from the fashionable and idle; whilst it is not inconveniently remote from either extremity. The building was commenced on the 30th of April, 1827, when the Duke of Sussex laid the first stone, in the presence of a large concourse of noblemen and gentlemen. The design is by William Wilkins, Esq., R.A., who has evinced in the principal elevation and general character of the edifice considerable taste and science. When completed, it is intended to consist of a central part, and two wings projecting at right angles from the extremities of the former. The first portion only of this is at present finished. It extends from north to south 430 feet, with a depth, from east to west, including the two semicircular theatres, of about 200 feet. The elevation is at once classical and chaste, having a bold and rich portico in the centre, elevated on a plinth, to the height of the first story (19 feet,) and is approached by numerous steps, which are arranged to produce a fine effect. Twelve Corinthian columns support a flattened pediment, in the tympanum of which is to be a composition in basso-relievo, analogous to science and literature. Behind this pediment is a cupola, finished by a lantern light, in imitation of a peripteral temple, crowning and ornamenting a grand octagonal vestibule, or saloon. North of this is the museum of natural history, 118 feet by 50, and 23 feet in height, opening to the museum of anatomy, which latter communicates with two rooms for professors, and to one of the large theatres, or lecture-rooms. East of the vestibule is a large hall, and to the south is the great library, corresponding in size, &c. with the museum of natural history; the
