ARGENTUM VIVUM, Age 3500 There is evidence t o indicate t h a t the metal Mercury was known as early as 1600 B.c. Anthropologists have discovered amulets, containing what appeared t o be Mercury, entombed with Egyptian mummies. During t h e R o m a n era, the fluid m e t a l was called argentum vivum, or living silver. Since the time of t h e ancients, mercury salts h a v e achieved a n ever-increasing importance. Metallurgy, chemistry, medicine, temperature recording, a n d electrical conversion are a few of the categories in which Mercury plays an important rôle today. T h e wide variety of analytical and industrial uses of mercury 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. T h e Merck label, which conforms t o A.C.S. methods of stating m a x i m u m impurities, always has been the chemist's assurance of uniformly high quality.
