A CONNECTED history of the work of the Geological Survey of Great Britain has long been overdue. It is true that many details can be gathered from the lives of Edward Forbes, Murchi-son and Ramsay, from Geikie's "Long Life's Work", and from the registers of the Royal School of Mines and the Royal College of Science. But what was wanted was an impersonal account of the service and its work, written from the point of view of the service itself ; and that has now been furnished by Sir John Flett in "The First Hundred Years of the Geological Survey of Great Britain"*. It was the last act of his thirty-five years' service, during fifteen of which he was director, and for another ten assistant to the director for Scotland. It marks the centenary in 1935 of the Survey, and the opening of the new Geological Museum at Kensington by H.R.H. the Duke of York, now His Majesty King George VI.
