Charles II.'s gift of Chelsea College to the Royal Society had proved a gift of greater magnitude than they had been able to deal with, and the building had remained unused since 1669. Nor did their funds allow them to make use of Mr. Howard's donation of a piece of land, though the ever-ready Sir Christopher produced a design for it of some size, on the principle 'that a fair building may be easier carried on by contribution with time, than a sordid one.' At last, in 1681, he proposed the sale of Chelsea College back again to King Charles, and Wren and Evelyn undertook to manage what must have been rather a delicate transaction. During the negotiation Sir Stephen Fox came to Evelyn and proposed that the King should buy it, and build there a hospital for soldiers. The proposal came well from Sir Stephen, who, originally a chorister of Salisbury Cathedral, by the favour and help of Bishop Duppa first, and then by that of the King, and most of all by his own honesty and dexterity, became paymaster to the whole army and acquired an honest and unenvied fortune. The King agreed to the plan, and the matter was arranged by Wren, Evelyn, and Fox, who was a liberal benefactor to the college. The three men went across to Lambeth to their old friend Sancroft and acquainted him with the plan, and received his approval. Wren set instantly to work, and in August 1682 the foundations were being laid; the whole building was not completed until William and Mary's reign; but during all that time Wren's energy and care never flagged, but were extended even to the minutiæ of the regulations, all of which he drew up, for the health, comfort, and economy of the building. As architecture the building has been severely criticised; but when the worst is said, it still remains picturesque, cheerful and spacious, and a beautiful object as seen from the Thames. The Royal Society continued its meetings at Gresham College, which it did not quit until, in 1710, the members purchased a house in Crane Court, which has only very lately been pulled down. The next year saw many of Wren's churches finished. All Hallows the Great, in Thames Street, a plain brick and stone edifice with a strong square tower, was then completed: it, like by far the greater number of the City churches, had been repaired and beautified under the vigorous rule of Laud while Bishop of London. Thomas White, who came into the living a few months only before the Fire, was afterwards as Bishop of Peterborough one of the famous 'Seven Bishops.' At the time when Wren rebuilt the church the living was held by the learned church historian, Dr. William Cave.[183]
