Abstract
IT is well known that the empiric rules of substitution, which have been evolved from the study of the aromatic compounds, may enable a chemist to predict roughly the result of such a process; it is equally well known that not one of these rules is free from exceptions. The absence of any rational theory underlying the process or the lack of novelty in the methods employed may have deterred chemists in recent years from following up what was formerly regarded as one of the most attractive lines of inquiry; but it is quite certain that very little in the way of systematic study, especially of a quantitative character, has been done in this field of research. Yet the process of substitution possesses not merely a theoretical significance; it has a very considerable technical value. The formation of halogen, nitro and sulphonic derivatives of aromatic compounds are among the most familiar technical operations of the colour-maker.
