The contributions of the Society to the æsthetic studies of the time also deserve notice. The excellent design to publish _Select Specimens of Antient Sculpture preserved in the several Collections of Great Britain_ was carried into effect by Messrs. Payne Knight and Mr. Towneley, 2 vols. folio, 1809-1835. Then followed Mr. Penrose's _Investigations into the Principles of Athenian Architecture_, printed in 1851. About the year 1820, those admirable monuments of Grecian art, called the Bronzes of Siris, were discovered on the banks of that river, and were brought to this country by the Chevalier Brondsted. The Dilettanti Society immediately organized a subscription of 800_l._, and the Trustees of the British Museum completed the purchase by the additional sum of 200_l._ It was mainly through the influence and patronage of the Dilettanti Society that the Royal Academy obtained a Charter. In 1774, the interest of 4000_l._ three per cents. was appropriated by the former for the purpose of sending two students, recommended by the Royal Academy, to study in Italy or Greece for three years. In 1835 appeared a Second Volume on Ancient Sculpture. The Society at this time included, among a list of sixty-four names of the noble and learned, those of Sir William Gell, Mr. Towneley, Richard Westmacott, Henry Hallam, the Duke of Bedford, Sir M. A. Shee, P.R.A., Henry T. Hope; and Lord Prudhoe, afterwards Duke of Northumberland. That a Society possessing so much wealth and social importance as the Dilettanti should not have built for themselves a mansion is surprising. In 1747 they obtained a plot of ground in Cavendish Square, for this purpose; but in 1760, they disposed of the property. Between 1761 and 1764 the project of an edifice in Piccadilly, on the model of the Temple of Pola, was agitated by the Committee; two sites were proposed, one between Devonshire and Bath Houses, the other on the west side of Cambridge House. This scheme was also abandoned. Meanwhile the Society were accustomed to meet at the Thatched House Tavern, the large room of which was hung with portraits of the Dilettanti. Sir Joshua Reynolds, who was a member, painted for the Society three capital pictures:--1. A group in the manner of Paul Veronese, containing the portraits of the Duke of Leeds, Lord Dundas, Constantine Lord Mulgrave, Lord Seaforth, the Hon. Charles Greville, Charles Crowle, Esq., and Sir Joseph Banks. 2. A group in the manner of the same master, containing portraits of Sir William Hamilton, Sir Watkin W. Wynne, Richard Thomson, Esq., Sir John Taylor, Payne Galway, Esq., John Smythe, Esq., and Spencer S. Stanhope, Esq. 3. Head of Sir Joshua, dressed in a loose robe, and in his own hair. The earlier portraits are by Hudson, Reynolds's master.
