Strahan, Printers-Street, London * * * * * * * * * * * * * * Terminology oxy-muriatic acid = chlorine (proposed as an element in 1815: see Conversation XIX) “columbium or tantalium” = niobium and tantalum (the two elements always occur together, and were not recognized as separate until much later in the 19th century) phosphat of lime = calcium diphosphate _or_ calcium (the element calcium was isolated in 1808, but is named only once in this 1817 edition) glucium = beryllium (Humphry Davy’s name for the element) muriatic acid = hydrochloric acid (still called “muriatic acid” for some commercial uses) muriat of lime = calcium chloride oxymuriate of potash = potassium chlorate muriat of soda = sodium chloride (table salt) carbonic acid = carbon dioxide Note also: simple body, fundamental principle = element fecula = starch (usually spelled “fæcula”) spirit of wine = alcohol philosopher = scientist arts = industry, manufacture, crafts etc. (seldom “fine arts”) Some essential concepts relating to living things--photosynthesis, microorganisms, the cell, proteins--are either unknown or not mentioned. The atom theory had been proposed, but not by Humphry Davy; it is not mentioned in this book.
