“…Malissa and Jellinek (91) have discussed automation in analytical chemistry. Busev (19) has summarized the work done during the past fifty years in the USSR on the analytical chemistry of rare elements and Feigl has reviewed (38) a number of spot tests that can be based on the formation and reactions of mercuric cyanide. An important review has appeared dealing with the applications of digital computers in analytical chemistry (24), and interesting discussions have appeared dealing with the appraisal of various analytical methods (134) in which the classical methods are compared with some of the modern "instrumental" techniques.…”
