Lo! was Charles Forts third book. In it Fort examines a multitude of scientific anomalies. Fort is widely credited to have coined the now-popular term teleportation in this book, and here he ties his previous statements on what he referred to as the Super-Sargasso Sea into his beliefs on teleportation. He would later expand this theory to include purported mental and psychic phenomena in his fourth and final book, Wild Talents.
