Regent’s Park.—This beautiful park is situated considerably away from the other parks, in a northerly direction from the Marylebone Road. It consists of a nearly circular enclosure of about 470 acres, laid out on the approved principles of landscape gardening; its centre is enriched with lakes, plantations, shrubberies, and beds of flowers. Many of the Metropolitan Volunteer Rifle Corps exercise and drill in this park, in all except the winter months. The park is surrounded by extensive ranges of buildings, forming terraces, variously designated, and decorated with sculpture in agreement with their respective orders of architecture: producing an effect of much grandeur, though, in some instances, of questionable taste. Three or four isolated mansions occupy sites within the park. The outer drive is two miles in circuit; the inner drive is a perfect circle, with two outlets. At Mr. Bishop’s Observatory, near this inner circle, Mr. Hind made most of his important discoveries of asteroids and comets. Near the south-eastern corner of the park the _Colosseum_ stands conspicuous. It is now closed. The Zoological and Botanical Gardens will be described presently. Some distance north of the Colosseum are St. Katharine’s Hospital and Chapel—a very luxurious provision for ‘six poor bachelors and six poor spinsters.’ Near the Colosseum was the once celebrated exhibition called the _Diorama_, which was some years ago converted into a Baptist chapel, at the cost of Sir Morton Peto. Primrose Hill.—This spot now deserves to be ranked among the public parks of London. It is immediately north of the Regent’s Park. The Crown owned part of it, and obtained the rest by purchase from Eton College. The hill-top, the grassy slopes, and the gravelled paths are kept in excellent order; and a stranger should not lose an opportunity of viewing the ‘world of London’ from this spot in early morning. By permission of the authorities, a refreshment-room has been established for visitors; and a ‘Shakspeare Oak’ planted, April 23, 1864, which, however, “came to grief.”
