Homberg, William

In 1702, William Homberg heated borax with iron(n) sulphate and obtained by sublimation a compound he called sedative salt , though it was not a salt but boric acid.94 The boron hydrides, first studied by A. Stock in 1909, have provided a rich source of new chemistry.95 Pliny described a silvery cup, lighter than any known metal, once owned by the emperor Tiberius. Some have speculated that the Romans might have stumbled on aluminium.96 Though alum was known in antiquity, the... 

Homberg (1700 see Vol. Ill, p. 46) had the idea that in finding the force of an alkali (coral, oyster shells, etc.) for an acid account must be taken of the time necessary for the acid to absorb the alkali. William Lewis (see Vol. II, p. 762) connected the powerfulness of acids with their activity as measured by the velocity of their action on bodies ... 

Most of the methods in use for the estimation of glucuronides are based on the reaction of hexuronic acids with naphthoresorcinol to form a colored complex (Tollens reaction). Several procedures have been described, e. g., Maughan, Evelyn, and Browne (62), Hanson, Mills, and Williams (50), and Fishman, Smith, Thompson, Bonner, Kasdon, and Homberger (41).
