hitherto known only indirectly by means of X-rays, stood outlined boldly on a fluorescent screen, showing nine atoms in their correct positions in the space lattice, a cube, with one atom in each corner and one in the center. The atoms in the crystal lattice of the tungsten appeared on the fluorescent screen as points of light, arranged in geometric pattern. Against this crystal cube of light the bombarding molecules
