Abstract
IT is over forty years since the late Dr. Peter Griess placed at the disposal of chemists a reaction which has since proved of such importance, both scientifically and technically, that a large literature is now in existence dealing with the class of compounds known as azo- and diazo-compounds. From the industrial side, the most important development has been the manufacture of a group of colouring-matters which are now turned out on a colossal scale, and which are so numerous in individual members, that in the last edition of the “Tabellarische Übersicht” of Schultz and Julius (1897) no less than two hundred and seventy-three distinct technical products of this class were catalogued. The present little work is one of the useful “Aide-Mémoiré” series from the “Encyclopédic Scientifique,” published under the direction of M. Léauté of the Institute. It is fairly brought down to date, and contains in a handy and portable form a tabular list of the colouring-matters in question, including also the nitro- and azoxy-compounds which find place in technology. The little volume will be found valuable by all engaged in this department of chemical industry.
