In 1908, the Enghsh chemist Samuel Henry Clifford Briggs (1880 1935) proposed formulas for complexes that he claimed agreed with experimental data and showed how the afiSnities of the atoms are disposed in the molecule. He did not claim to be proposing a new theory of valence. Like Werner, he thought that a totally comprehensive and satisfactory theory of valence will not be possible until we have a much more complete knowledge of the constitution of molecular compounds, and also of the nature of chemical affinity, than we possess today . He later (1917) reinterpreted his formulas in terms of the electronic theory of valence, differentiated between what he called primary and secondary affinity (similar to Werner s primary and secondary valences), and proposed three different types of chemical combinations.
