One of the earliest appointments made at the Restoration was that of Dr. Bruno Ryves[85] to be Dean of Windsor and Registrar of the Garter. In the August of 1660, Christopher Wren went to Windsor, and solemnly delivered to the Dean the three registers and the note books of the Order of the Garter, which Dean Wren had, with so much difficulty, recovered and hidden carefully until, at his death, he transferred the charge to his son. Dean Ryves gave a written acknowledgment to Christopher that he had safely received the books, and the service his father had done in preserving them was fully admitted. Gresham College had been cleansed and set in order after the Restoration, and Christopher resumed his lectures there, which were largely attended. After one of these lectures given in November, Lord Brouncker, Mr. Robert Boyle, Dr. Goddard, Dr. Petty, Dr. Wilkins, Sir Robert Moray and others withdrew with Wren to his room, where they discussed a project for a philosophical College or Society. It was not an entirely new idea, for it had been a favourite scheme of Evelyn's, also of the poet Cowley's.[86] It was not a matter to be arranged in one sitting, and accordingly they settled to meet weekly in Wren's rooms after his lectures, and agreed that for incidental expenses each should pay down ten shillings and subscribe a shilling weekly. A list was made of between thirty and forty probable members, among them those previously mentioned, and Christopher's old friend Sir C. Scarborough, Dr. Seth Ward, Matthew Wren, Cowley, Sir Kenelme Digby, Mr. Evelyn and others. Sir Robert Moray undertook to explain the project to King Charles, and brought back a gracious message that he well approved of it, and would be ready to give it every encouragement. One of the first orders of the Society was that Wren should at the next meeting of the Society bring in his account of the pendulum experiment, with his explanation of it: this experiment related to 'the determination of a standard measure of length by the vibration of a pendulum.'[87] There followed experiments for the improvement of shipping, in which Wren worked with Dr. Petty and Dr. Goddard. It was a question to what mechanical powers sailing, especially when against the wind, was reducible; 'he showed it to be a wedge; and he demonstrated how a transient force upon an oblique plane would cause the motion of the plane against the first mover. He made an instrument that mechanically produced the same effect and showed the reason of sailing to all winds.' But to give all Christopher's experiments would be to write over again the already well-told history of the Royal Society. It had few more assiduous members. [_SAVILIAN PROFESSORSHIP._]
