Not illustrated. 1907 Excerpt: ... of the bases in the other column are equivalent, in that these are the weights (according to Richter) which severally neutralize one and the same weight of any base, and one and the same weight of any acid, to form neutral salts. In 1803, Richter adopted Fischer's way of presenting the results of the analyses of neutral salts, and gave a table of the equivalent weights of eighteen acids and thirty bases.1 The ninth part of Richters Neurn Gegenntdnde is concerned with determinations of the weights of fifteen metals which dissolve in 1000 parts of each of the acids, sulphuric, hydrochloric and nitric, to form neutral salts. He concluded that the weights of the metals were in arithmetical progression, and he used this hypothesis to correct his experimental results. Richter supposed that the metals were first oxidized, and the metallic earths were then dissolved. He called the process of oxidation die Lebensluftstoffung der Metalle; and he said that the weight of Lebensluftstoff which combines with those weights of metals that saturate a constant weight of an acid is itself constant. This is equivalent to saying, if we use the language of to-day, that those weights of various bases which saturate a constant weight of an acid contain the same weight of oxygen. The following tables are taken from Part IX, pp. 126, 127 (1798) of Richter's Neurn Gegenstande. (See next page.) Richter was constantly seeking for regularities in the proportions wherein substances react, and endeavouring to express tIn the article "Neutralitat" in Richter's edition of Bourguet's Chemical Dictionary. his results in a general form wherefrom he could deduce the quantitative course of other reactions. As examples of Richter's methods of experiment and calculation, I ive his deter...
