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 small library; rooms for the librarian, for apparatus, and also another large theatre.  The ground-floor consists of rooms for lectures, the Professor’s offices, laboratory, museum, a spacious cloister 213 feet by 24; rooms for the anatomical school, &c.  In the basement are other apartments for the anatomical schools, for the chemical laboratory, the students’ common room, kitchen, stewards’ room, refreshment rooms, housekeeper’s room, vaults, &c.

At the British Museum a new room, to contain the late king’s library, has been built and fitted up from the designs of Mr. R. Smirke.  It is the largest apartment in this country, its measurement being 300 feet in length, by 30 feet in width, and 30 feet high,
