The Silent Worldby J Y Cousteau By the famous Jacques Yves Cousteau, who taught so many so much about the underwater world. This book tells of his first experiments with the 'iron lung' which revolutionised scuba diving. It also tells of Cousteau's dives in various locations around the world. It's great stuff. Not least because of the wonderful old photographs including one of the Cousteau family on their 'usual Sunday afternoon under water excursion'. Hardback in
