All the world's prizes are captured by those who have seasoned their energy with the spice of originality- and originality means the habit of clear and fresh thinking. Even the best of us have a tendency to fall into mental ruts, to go plodding on year after year, in the same track, to do things without knowing precisely why. The way to keep alive, the way to be original, the way to be a success, is to talk with brainy people and to read books that make you think. That's the reason The New Science Library is a cure for mental paralysis. It contains the best work of Darwin, Huxley, Spencer, Tyndall and great leaders of modern thought. It will tell you what the famous Darwinian theory is; how the planets are weighed and their motions charted; what radium is; how liquid air is made and usedand ten thousand other interesting things. It is a work to be read and enjoyed, for it is written in a clear and interesting style-not abstruse or technical. The work consists of sixteer superb volumes, handsomely printed and bound.
