S O D I U M — t h e water-splitting metal t h a t Davey discovered in 1807, today is a prime industrial and laboratory servant. Our world is surrounded by products t h a t employ sodium and its compounds in their manufacture. The gulfa-drugs, fluorescent lighting, and plastics are just a few of these essentials t o modern everyday living. The variety of analytical and industrial uses of sodium compounds demands chemicals of maximum purity and dependability. Merck & Co., Inc., for almost four generations, has set the pace in production of fine laboratory chemicals. The Merck label, which conforms to A. C. S. methods of stating maximum impurities, always has been the chemist's assurance of uniformly high quality.
