When Flamstead had completed his catalogue, he proposed to publish it, and prince Greorge of Denmark, knowing that Flamstead had expended on his instruments two thousand pounds more than his salary, offered to pay for the printing. A committee, consisting of Newton, Sir Christopher Wren, Dr. Arbuthnot, Dr. Gregory, and Sir. Roberts, were appointed to superintend this publication.

He was summoned before the Royal Society to answer whether he
