    A somewhat remarkable result follows from the work of the Braggs on the structure of crystals. They show that in a crystal of sodium chloride, for example, each Fig. i. Model of Crystal of Sodium Chloride. Black—Na atoms. White—Cl atoms. (Bragg’s “ X-rays and Crystal Structure.”) sodium atom is joined to six chlorine atoms, and each chlorine to six sodium atoms (Fig. i). Hence there is no mole- cule of NaCl in the solid. Further, if it is completely dissociated in solution,
