The Oxford and Cambridge Club-house, 71, Pall Mall, for members of the two Universities, was designed by Sir Robert Smirke, R.A., and his brother, Mr. Sydney Smirke, 1835-8. The Pall Mall façade is 80 feet in width by 75 in height, and the rear lies over against the court of Marlborough House. The ornamental detail is very rich: as the entrance-portico, with Corinthian columns; the balcony, with its panels of metal foliage; and the ground-story frieze, and arms of Oxford and Cambridge Universities over the portico columns. The upper part of the building has a delicate Corinthian entablature and balustrade; and above the principal windows are bas-reliefs in panels, executed in cement by Nicholl, from designs by Sir R. Smirke, as follows:--Centre panel: Minerva and Apollo presiding on Mount Parnassus; and the River Helicon, surrounded by the Muses. Extreme panels: Homer singing to a warrior, a female, and a youth; Virgil singing his Georgics to a group of peasants. Other four panels: Milton reciting to his daughter; Shakspeare attended by Tragedy and Comedy; Newton explaining his system; Bacon, his philosophy. Beneath the ground-floor is a basement of offices, and an entresol or mezzanine of chambers. The principal apartments are tastefully decorated; the drawing-room is panelled with _papier mâché_; and the libraries are filled with book-cases of beautifully-marked Russian birchwood. From the back library is a view of Marlborough House and its gardens. THE GUARDS' CLUB. Was formerly housed in St. James's-street, next Crockford's, north; but, in 1850, they removed to Pall Mall, No. 70. The new Club-house was designed for them by Henry Harrison, and remarkable for its compactness and convenience, although its size and external appearance indicate no more than a private house. The architect has adopted some portion of a design of Sansovino's in the lower part or basement. THE ARMY AND NAVY CLUB.
